Fully redundant end-to-end architecture maximizing server availability from the network
Support for IGMP snooping for multicasting
Support for UFD for network path resiliency. It works in conjunction with NIC teaming functionality
that is supported on the blade servers. This feature tracks the link state on uplink ports. When an
uplink port goes down or is in STP blocking state, this feature will enable the switch to auto disable
the downlinks which are connected to the blade server NICs. This enables NIC teaming software to
detect link failure on the primary NIC port and fail over to the secondary NIC in the team. As a
result, the secondary path is enabled for continued blade server access.
When used in conjunction with UFD, NIC teams on the blade server must be configured for switch
redundancy. That is, the team will span ports on both Switch 1 and Switch 2. See the HP network
adapter teaming: load balancing in ProLiant servers running Microsoft Windows operating systems

Switch architecture
The HP c-Class BladeSystem provides Ethernet switching technology for network cable reduction.
The switch does not affect or determine NIC enumeration and the associated mapping of NIC interfaces
to switch ports. The numbering of the NICs on the server (for example, NIC 1, NIC 2, NIC 3) is
determined by the server type, the server operating system, and what NICs are enabled on the server.
Port Mapping
For detailed port mapping information, see the HP BladeSystem enclosure installation poster or the HP
BladeSystem enclosure setup and installation guide on the HP website
Dual switches
In a dual switch configuration, two switches in the server blade enclosure provide switch redundancy and
redundant paths to the network ports on the server blades. Each switch has five external Gigabit Ethernet
ports and sixteen internal Gigabit Ethernet ports providing connectivity to the blade servers within the
enclosure.
Each pair of switches consolidates up to thirty-two Gigabit Ethernet signals into one-to-ten Gigabit ports
(on the back of the enclosure).
Redundant crosslinks
In a dual switch configuration, the two switches are connected through redundant Gigabit crosslinks.
These two crosslinks provide an aggregate throughput of 2 Gb/s for traffic between the switches.
These crosslinks are disabled by default. The crosslinks must be enabled for use.
Introduction 9
Redundant paths to server bays
In a dual switch configuration, redundant Ethernet signals from each blade server are routed through the
enclosure backplane to separate switches within the enclosure. This configuration provides redundant
paths to each server bay.
Redundant Ethernet signals from each blade server are routed through the enclosure backplane to
separate switches within the enclosure. However, specific switch port to server mapping varies depending
on which type of server blade is installed.
On a heavily used system, using a single uplink port for 32 Ethernet signals causes a traffic bottleneck.
For optimum performance, HP recommends using at least one uplink port per switch.
Supported technologies
Layer 2 switching
The switch uses Gigabit Layer 2 switching technology. Layer 2 refers to the Data Link layer of the OSI
model, which is concerned with moving data packets across a network by enforcing CSMA/CD. This
layer performs:
•
•
•
•
•
Ethernet packet framing
MAC addressing
Physical medium transmission error detection
Medium allocation (collision avoidance)
Contention resolution (collision handling)
Layer 2 switching technology allows the switch to look into data packets and redirect them based on the
destination MAC address. This reduces traffic congestion on the network because packets, instead of
being transmitted to all ports, are transmitted to the destination port only.
Layer 3 switching
In addition to Layer 2 features, the switch also supports Layer 3 switching. Layer 3 switching features
include:
•
•
•
•
IP forwarding
Static routing
Dynamic routing based on RIP V1/V2 or OSPF protocols
High availability VRRP
Layer 3 switching provides more power, flexibility, and security capabilities to network administrators.
Network traffic is managed much more efficiently and broadcast traffic between servers remains within
the enclosure. Security features provide added protection for switch configuration data, while packet
filtering helps secure and segment sensitive traffic or network access.
IEEE 802.1 Q-based VLAN
The switch provides support for a total of 255 IEEE 802.1Q VLANs for server grouping and isolation. A
VLAN is a network segment configured according to a logical scheme rather than a physical layout.
VLANs are used to combine any collection of LAN segments into an autonomous user group that appears
as a single LAN.
Introduction 10
VLANs also logically segment the physical network into different broadcast domains so that packets are
forwarded only between ports within the VLAN. This technology enhances performance by conserving
bandwidth and improves security by limiting traffic to specific domains. For example, isolate the server
blade iLO ports from the rest of the NICs. The iLO ports on Switch 2 are assigned to their own VLAN and
go to a dedicated uplink or share an uplink using VLAN tagging.
IMPORTANT: The greater the number of VLANs, the greater the switch CPU utilization. For
maximum switch performance, HP recommends being judicious when configuring the number
of VLANs.
NOTE: VLAN 4095 is reserved for future functionality.
Spanning Tree Protocol
The switch supports IEEE 802.1D STP, which allows the blocking of links that form loops between switches
in a network. When multiple links between switches are detected, a primary link is established.
Duplicated links are blocked from use and become standby links. If the primary link fails, the standby link
is activated.
In addition, the switch provides a spanning tree domain per VLAN. The switch is compatible with Cisco®
PVST+ and Cisco PVST, when the other device is configured as untagged or configured to use 802.1q
tagging. Sixteen spanning tree domains are supported per switch.
NOTE: STP 16 is reserved for future functionality.
The switch also provides IEEE 802.1s-based MSTP and IEEE 802.1w-based RSTP.
SNMP
The switch is configured and monitored remotely from an SNMP-based network management station. The
switch supports industry-standard SNMP MIBs and proprietary HP enterprise switch MIBs for fault
detection and monitoring of switch functionality. In addition, the switch supports various environmental
traps such as temperature and fan failure traps.
To secure the management interface, the switch administrator configures community strings with two levels
of access: Read and Read/Write. Access to the switch is also restricted to only management stations that
are members of a specific IP network. This is achieved by configuring the address/mask of that specific
network as a restricted management network address/mask.
Port mirroring
The switch allows mirroring of one or multiple ports (source ports) to another port (destination port) for
network monitoring and troubleshooting purposes. This technology offers a way for network packet
analyzers to view the traffic moving through the switch by providing a copy of the traffic that is currently
being passed through any other port. The packets are sent to a network packet analyzer or other
monitoring device attached to the mirror port.
Port trunking and load balancing
The switch supports EtherChannel compatible IEEE 802.3ad (without LACP) port trunking allowing several
ports to be grouped together and act as a single logical link called a trunk. This feature provides a
Introduction 11
bandwidth that is a multiple of the bandwidth of a single link. It also improves reliability since load
balancing is automatically applied to the ports in the trunked group. A link failure within the group causes
the network traffic to be directed to the remaining links in the group.
TFTP support
TFTP support allows the switch firmware to be upgraded by downloading a new firmware file from a TFTP
server to the switch. Firmware images of the switch are also uploaded to a TFTP server, a configuration
file is downloaded into a switch from a TFTP server, and configuration settings are saved to the TFTP
server.
Store and forward switching scheme
The switch provides a store and forward switching scheme that allows each packet to be buffered (stored)
before it is forwarded to its destination. While this method creates latency, it improves reliability in a
heavily used switch. Packets that cannot be forwarded are saved immediately, rather than dropped, so
that packets behind them are less likely to be dropped in periods of heavy usage.
BOOTP
By default, the switch is configured to obtain an IP address from a BOOTP server during the boot process.
The IP settings are also manually configured by means of the serial interface. The IP settings are
configurable from the browser-based interface, but because the connection is based on an IP address for
these interfaces, users will have to reconnect with the newly assigned IP address.
NTP
The switch maintains the current date and time. This information displays on the management interfaces
and is used to record the date and time of switch events. Current date and time information are manually
set on the switch or are obtained through NTP. NTP allows the switch to send a request to a primary NTP
server in each polling period asking for GMT.
RADIUS
The switch supports the RADIUS method to authenticate and authorize remote administrators for managing
the switch. This method is based on a client/server model. The RAS, the switch, is a client to the back-end
database server. A remote user (the remote administrator) interacts only with the RAS, not the back-end
server and database.
RADIUS authentication consists of:
•
•
•
A protocol with a frame format that utilizes UDP over IP, based on RFC 2138 and 2866
A centralized server that stores all the user authorization information
A client, in this case, the switch
The switch, acting as the RADIUS client, communicates to the RADIUS server to authenticate and authorize
a remote administrator using the protocol definitions specified in RFC 2138 and 2866. Transactions
between the client and the RADIUS server are authenticated using a shared key that is not sent over the
network. In addition, the remote administrator passwords are sent encrypted between the RADIUS client
(the switch) and the back-end RADIUS server.
The benefits of using RADIUS are:
•
Authentication of remote administrators
Introduction 12
•
•
•
Identification of the administrator using name/password
Authorization of remote administrators
Determination of the permitted actions and customizing service for individual administrators
TACACS+
The switch supports the TACACS+ method to authenticate, authorize, and account for remote
administrators managing the switch. This method is based on a client/server model. The switch is a client
to the back-end TACACS+ AAA server. A remote user (the remote administrator) interacts only with the
client, and not with the back end AAA server.
The TACACS+ AAA method consists of:
•
•
A protocol with a frame format that utilizes TCP over IP
A centralized AAA server that stores all the user authentication, authorization, and accounting (of
usage) information
•
A NAS or client (in this case, the switch)
The switch, acting as the TACACS+ client or NAS, communicates to the TACACS+ server to authenticate,
authorize, and account for user access. Transactions between the client and the TACACS+ server are
authenticated using a shared key that is not sent over the network. In addition, the remote administrator
passwords are sent encrypted between the TACACS+ client (the switch) and the back-end TACACS+
server.
The switch supports:
•
•
•
Only standard ASCII inbound login authentication. PAP, CHAP, or ARAP login methods are not
supported. One-time password authentication is also not supported.
Authorization privilege levels of only 0, 3, and 6. These map to management levels of user, oper,
and admin, respectively.
The accounting attributes of protocol, start_time, stop_time, and elapsed_time. For BBI users,
accounting stop records are only sent if the user presses the QUIT button.
SSH and SCP
SSH and SCP use secure tunnels to encrypt and secure messages between a remote administrator and the
switch. Telnet does not provide this level of security. The Telnet method of managing a switch does not
provide a secure connection.
SSH is a protocol that enables remote administrators to log securely into the switch over a network to
execute management commands.
SCP is used to copy files securely from one machine to another. SCP uses SSH for encryption of data on
the network. On a switch, SCP is used to download and upload the switch configuration via secure
channels.
XModem
The switch supports XModem for transferring files during direct dial-up communications. XModem sends
blocks of data in 128-byte blocks, and includes an error-detection system called a checksum. When the
data is received, the error detection system ensures that the entire message reached its destination. If not,
the receiving computer sends a request for retransmission of the data.
Introduction 13
IGMP Snooping
The switch supports IGMP Snooping for multicasting. Both Version 1- and Version 2-based IGMP
Snooping are supported. In addition, auto detection of the multicast router port and manual configuration
of the multicast router port is supported. For efficient multicast traffic management, the IGMP Filtering
option is supported.
Jumbo frames
By default, the switch supports jumbo frames up to 9216 bytes, which help reduce server CPU utilization
and increase application throughput. No configuration is required. The switch does not fragment frames
as they exit, or assemble packets into jumbo frames as they enter the switch.
Auto-MDI/MDIX
The switch Ethernet ports are MDI/MDI crossover capable. MDI/MDIX is a type of Ethernet port
connection using twisted pair cabling. The MDI is the component of the MAU that provides the physical
and electrical connection to the cabling medium. An MDIX is a version of MDI that enables connection
between like devices. MDI ports connect to MDIX ports via straight-through twisted pair cabling whereas
both MDI-to-MDI and MDIX-to-MDIX connections use crossover twisted pair cabling. The switch has the
capability to automatically detect the cable selection/type, making the distinction between a straight-
through cable and a crossover cable unimportant.
Auto-negotiation of duplex mode and speed
Auto-negotiation of duplex mode and speed are configured on the switch. Network adapters that support
multiple data speeds, such as Fast Ethernet and Gigabit Ethernet, choose the speed at which they run
through a procedure called auto-negotiation. Auto-negotiation involves probing the capability of the
network using low-level signaling techniques to select compatible Ethernet speeds. Auto-negotiation was
originally developed to make the migration from traditional Ethernet to Fast Ethernet products easier.
Redundant images in firmware
The switch stores up to two different software images, called image1 and image2, as well as boot
software, called boot. When downloading new software, the ability to specify where it is to be placed
(into image1, image2, or boot) is activated.
For example, if the active image is currently loaded into image1, load the new image software into
image2. This allows a test of the new software and the option to revert back to the original image stored
in image1, if needed.
CAUTION: Unlike the firmware that has two images, there is only one image of boot
supported. Upgrading the boot image replaces the original boot image.

Planning the switch configuration
NOTE: Only one port number can be used at a time. SFP transceiver ports have priority over
the RJ-45 ports.
The switch ships with a default configuration in which all downlink and uplink ports are enabled and
assigned a default VLAN with a VID equal to 1. This default configuration simplifies the initial setup by
allowing use of a single uplink cable (from any external Ethernet connector) to connect the server blade
enclosure to the network. By default, the X-connect ports (17 and 18) are disabled. Assess the particular
server environment to determine any requirements for other considerations.
The switch does not affect or determine NIC numeration and the associated mapping of NIC interfaces to
switch ports. The numbering of the NICs on the server (for example, NIC 1, NIC 2, NIC 3) is determined
by the server type, the server operating system, and which NICs are enabled on the server.
NOTE: Port 19 is reserved for connection to the Onboard Administrator module for switch
management. This allows a user to enable the functionality of future firmware upgrade
releases.
The Onboard Administrator module controls all port enabling. Enabling is based on matching ports
between the server and the interconnect bay. Before power up, the Onboard Administrator module
verifies that the server NIC option matches the switch bay that is selected and enables all ports for the
NICs installed.
For detailed port mapping information, see the HP BladeSystem enclosure installation poster or the HP
BladeSystem enclosure setup and installation guide on the HP website

Switch security
When planning the switch configuration, secure access to the management interface by:
•
•
•
Creating users with various access levels
Enabling or disabling access to various management interfaces to fit the security policy
Changing default SNMP community strings for read-only and read-write access
User, operator, and administrator access rights
To enable better switch management and user accountability, three levels or classes of user access have
been implemented on the switch. Levels of access to CLI, Web management functions, and screens
increase as needed to perform various switch management tasks. Conceptually, access classes are
defined as:
•
User interaction with the switch is completely passive. Nothing can be changed on the switch. Users
can display information that has no security or privacy implications, such as switch statistics and
current operational state information.
•
Operators can only effect temporary changes on the switch. These changes will be lost when the
switch is rebooted/reset. Operators have access to the switch management features used for daily
switch operations. Because any changes an operator makes are undone by a reset of the switch,
operators cannot severely impact switch operation.
Installing the switch 17
•
Administrators are the only ones that can make permanent changes to the switch configuration,
changes that are persistent across a reboot/reset of the switch. Administrators can access switch
functions to configure and troubleshoot problems on the switch. Because administrators can also
make temporary (operator-level) changes as well, they must be aware of the interactions between
temporary and permanent changes.
Access to switch functions is controlled through the use of unique surnames and passwords. Once
connected to the switch via the local console, Telnet, or SSH, a password prompt appears.
NOTE: It is recommended to change the default switch passwords after initial configuration
and as regularly as required under the network security policies. For more information, see the
HP GbE2c Ethernet Blade Switch for c-Class BladeSystem Command Reference Guide.
The default user name and password for each access level are:
User account
Description and tasks performed
Password
User
The user has no direct responsibility for switch management. He or she user
can view all switch status information and statistics, but cannot make
any configuration changes to the switch.
Operator
The operator manages all functions of the switch. The operator can
reset ports or the entire switch.
By default, the operator account is disabled and has no password.
Administrator
The super user administrator has complete access to all menus,
information, and configuration commands on the switch, including the
ability to change both the user and administrator passwords.
admin
Manually configuring a switch
The switch is configured manually using a command line interface, a browser-based interface, or an
SNMP interface. See the HP GbE2c Ethernet Blade Switch for c-Class BladeSystem Command Reference
Guide for more information on using these management interfaces to configure the switch.
After a switch is configured, back up the configuration as a text file to a TFTP server. The backup
configuration file is then downloaded from the TFTP server to restore the switch back to the original
configuration. This restoration is necessary if one of these conditions apply:
•
•
The switch configuration becomes corrupted during operation.
The switch must be replaced because of a hardware failure.
Configuring multiple switches
Configure multiple switches by using scripted CLI commands through Telnet or by downloading a
configuration file using a TFTP server.
Using scripted CLI commands through Telnet
The CLI, provided with the switch, executes customized configuration scripts on multiple switches. A
configuration script is tailored to one of the multiple switches, and then that configuration can be
deployed to other switches from a central deployment server.
Installing the switch 18
Using a configuration file
If planning for the base configuration of multiple switches in a network to be the same, manually
configure one switch, upload the configuration to a TFTP server, and use that configuration as a base
configuration template file.
Switch IP addresses are acquired by default using BOOTP, therefore, each switch has a unique IP
address. Each switch is remotely accessed from a central deployment server and an individual switch
configuration is downloaded to meet specific network requirements. See the HP GbE2c Ethernet Blade
Switch for c-Class BladeSystem Command Reference Guide for additional information on using a TFTP
server to upload and download configuration files.
Installing the switch
Preparing for installation
IMPORTANT: Before installing the switch, make a record of the MAC address (printed on the
MAC address label attached to the switch). This address is needed when configuring the
switch.
Installing the switch
CAUTION: Do not cable the switch until after configuration.
IMPORTANT: Make sure that the server NIC configuration matches the switch bay selected.
NOTE: When installing two switches, there are two switch interconnect ports between
adjacent I/O bays. These ports (17 and 18) are disabled by default. The ports must be
manually enabled to use.
Installing the switch 19
A successful installation is indicated by a green Health LED. If the Health LED is amber or power is not
applied to the switch, see the "Troubleshooting" section of the HP BladeSystem enclosure setup and
installation guide for more information.
Accessing the switch
The switch is accessed remotely using the Ethernet ports or locally using the DB-9 management serial port.
To access the switch remotely:
1.
Assign an IP address. By default, the switch is set up to obtain its IP address from a BOOTP server
existing on the attached network.
2.
3.
From the BOOTP server, use the switch MAC address to obtain the switch IP address.
From a computer connected to the same network, use the IP address to access the switch using a
Web browser or telnet application, which enables access to the switch BBI or CLI. The switch logon
prompt appears.
Installing the switch 20
NOTE: If the switch does not obtain the IP address by means of the BOOTP service, access the
switch locally and configure the IP address manually. After assigning the IP address to the
switch, then access the switch remotely.
To access the switch locally:
1.
Connect the switch DB-9 serial connector, using a null-modem serial cable to a local client device
(such as a laptop computer) with VT100 terminal emulation software.
2.
Open a VT100 terminal emulation session with these settings: 9600 baud rate, eight data bits, no
parity, one stop bit, and no flow control.
Logging on and configuring the switch
To log on to the switch:
1.
login prompt appears.
2.
Enter admin as the default administrator password.
The Main Menu appears and displays all administrator privileges:
See the HP GbE2c Ethernet Blade Switch for c-Class BladeSystem Command Reference Guide for
information on configuring the IP address, changing configuration settings, and monitoring switch
operation using one of the following interfaces:
•
•
Local RS-232 serial console management interface
Remote telnet console management interface
See the HP GbE2c Ethernet Blade Switch for c-Class BladeSystem Browser-based Interface Reference
Guide for information on using the embedded HTML interface to manage the switch from anywhere on
the network using a standard browser, such as Netscape Navigator or Microsoft® Internet Explorer.
describes how to use the MIBs to configure and monitor the switch using a generic SNMP manager, such
as HP OpenView Network Node Manager or HP Systems Insight Manager.
Installing SFP transceivers
Installing the switch 21
CAUTION: Do not install or remove fiber-optic SFP transceivers with cables attached because
of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP
transceiver. Disconnect all cables before removing or installing an SFP transceiver.
Removing and installing an SFP transceiver can shorten the useful life. Do not remove and
insert SFP transceivers more often than is necessary.
1.
Attach an ESD-preventative wrist strap to your wrist and to a bare metal surface on the chassis.
CAUTION: Do not remove the dust plugs from the fiber-optic SFP transceiver or the rubber
plugs from the fiber-optic cable until you are ready to connect the cable. The plugs and caps
protect the SFP transceiver ports and cables from contamination and ambient light.
2.
3.
Remove the dust cap and save for future use.
IMPORTANT: Use only SFP transceivers purchased from HP.
Insert the SFP transceiver.

Replacing an existing switch
CAUTION: Removing the switch from a powered enclosure results in the loss of network
communications between the server blade network ports that are connected through this switch
and the segment of network infrastructure those ports need to communicate.
For continued blade server network communication and services availability before removing
the switch, redirect critical high-availability services or applications to use the redundant
network ports available on those blade servers that are connected through the redundant
switch in the enclosure.
CAUTION: Do not cable the switch until after configuration.
To replace an existing switch:
1.
Save the configuration file to a TFTP server for later retrieval. For more information on saving a
configuration file to a TFTP server, see the HP GbE2c Ethernet Blade Switch for c-Class BladeSystem
Command Reference Guide.
2.
3.
Remove and label the cables.
Remove the switch.
4.
5.
Slide the new switch fully into the interconnect bay. For more installation information, see "Installing
Close the ejector lever and wait for the switch boot up completely.

Serial upgrade of operating system firmware procedure ............................................................................. 40
Introduction
Perform a serial download of the switch operating system firmware, or boot code firmware if upgrading a
switch directly from any existing OS or boot code images.
This procedure requires:
•
•
•
A computer running terminal emulation software
A standard null modem cable with a female DB-9 connector
A switch OS firmware and/or boot code images
Serial upgrade of boot code firmware image
procedure
To perform a serial upgrade of the switch boot code firmware image, usually named
pGbE2c_b_100.bin:
1.
2.
Using the null modem, connect the console port of the switch to the serial port of a PC that supports
XModem/1K XModem.
Start HyperTerminal (part of Microsoft Windows) or equivalent terminal emulation application
(depending on the computer operating system), and set the parameters for the terminal emulation
console:

8.
Be sure that the new switch boot code firmware file is available on the computer. This file can be
downloaded from the CD that is shipped with the switch or from the HP website
Select <Transfer-Send File> from the menu and choose these options in the Send File window:
The Send File window displays progress of the file transfer. The file transfer might take up to seven
minutes.
NOTE: Although slower, XModem also works if 1K MODEM is not used.
9.
After completing the transfer, a message displays how many bytes transferred, followed by another
message displaying the status of image extraction. Do not power cycle the switch during this
process. After extracting the image, it is updated to flash and a message with a progress indicator
displays as shown.
Performing a serial download 39
CAUTION: Do not power off the switch until the message: "Change your baud rate to 9600
bps and power cycle the switch," is displayed, otherwise, the switch will be inoperable.
10. Change the baud rate to 9600 and power off the switch, wait for a few seconds, and power on the
switch.
The switch boots with the new version of the boot code image that was just downloaded.

MIB overview
Management and statistics information is stored in the switch in the MIB. The switch supports several
standard MIBs. Values for MIB objects are retrieved with any SNMP-based network management
software.
In addition to the standard MIBs, the switch also supports its own proprietary enterprise MIB as an
extended MIB. The proprietary MIB is retrieved by specifying the MIB OID at the network manager
station.
MIB values are either read-only or read/write variables.
•
Read-only MIB variables are constants that are programmed into the switch or variables that change
while the switch is in operation. Examples of read-only constants include the number and types of
ports. Examples of read-only variables are the statistics counters, such as the number of errors that
have occurred or how many kilobytes of data have been received and forwarded through a port.
•
Read/write MIB variables are usually related to user-customized configurations. Examples include
the IP address of the switch, Spanning Tree Algorithm parameters, and port status.
SNMP Manager software
Using third-party vendor SNMP software to manage the switch allows access to proprietary enterprise
MIBs for the switch. The MIBs are found in the utilities on the HP website
If the software provides functions to browse or modify MIBs, the MIB values (if the MIB attributes permit
the write operation) are changeable. This process can be quite involved, because the MIB OIDs (available
in the MIB files) must be used and retrieved one by one.
Use an SNMP manager, such as HP OpenView Network Node Manager or HP Systems Insight Manager,
to access the enterprise-specific MIBs. Compile the MIBs into the MIB database and then use a MIB
browser to navigate through them. For detailed information, access the individual descriptions of each
MIB or see the documentation that came with the SNMP manager software.
The switch SNMP agent supports SNMP Version 1. Security is provided through SNMP community strings.
The default community strings are "public" for SNMP GET operation and "private" for SNMP SET
operation.
Users can specify up to two trap hosts for receiving SNMP traps. The agent sends the SNMP trap to the
specified hosts when appropriate. Traps are not sent if there is no host specified.

Grounding methods to prevent electrostatic discharge ................................................................................ 46
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow when setting up the
system or handling parts. A discharge of static electricity from a finger or other conductor may damage
system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the
device.
To prevent electrostatic damage:
•
•
•
•
•
Avoid hand contact by transporting and storing products in static-safe containers.
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
Place parts on a grounded surface before removing them from their containers.
Avoid touching pins, leads, or circuitry.
Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods to prevent electrostatic discharge
Several methods are used for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
•
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm 10 percent resistance in the ground cords.
To provide proper ground, wear the strap snug against the skin.
•
Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet
when standing on conductive floors or dissipating floor mats.
•
•
Use conductive field service tools.
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller
install the part.
For more information on static electricity or assistance with product installation, contact an authorized
reseller.
