Linksys EtherFast® II Series  
10/100 Managed 24-Port GigaSwitch  
The RJ-45 Ports  
Installing the GigaSwitch  
The 10/100 Managed 24-Port GigaSwitch is equipped with twenty-four auto-  
sensing RJ-45 ports. These RJ-45 ports support network speeds of either  
10Mbps or 100Mbps, and can operate in half- and full-duplex modes. Auto-  
sensing technology enables each port to automatically detect the speed of the  
device connected to it (10Mbps or 100Mbps), and adjust its speed and duplex  
accordingly.  
Pre-Installation Considerations  
Fast Ethernet Considerations  
If you will be using the GigaSwitch for Fast Ethernet (100Mbps) applications,  
you must observe the following guidelines:  
To connect a device to a port, you will need to use a network cable. UTP  
Category 3 cable is acceptable for 10BaseT networks, however, if you are  
using 100BaseTX devices you will need to use UTP Category 5 (or better)  
cable. For more information on twisted-pair cabling, refer to the Twisted-Pair  
Cabling section on page 80.  
• The maximum UTP cabling length using Category 3 cable is 328 feet (100  
meters).  
Full-Duplex Considerations  
As previously mentioned, the GigaSwitch provides full-duplex support for its  
RJ-45 ports. Full-duplex operation allows data to be sent and received simul-  
taneously, doubling a ports potential data throughput.  
If you will be using the GigaSwitch in full-duplex mode, the maximum UTP  
cable length using Category 5 cable is 328 feet (100meters).  
Positioning the GigaSwitch  
The Gigabit Expansion Ports  
Before you choose a location for the GigaSwitch, observe the following  
guidelines:  
The 10/100 Managed 24-Port GigaSwitch is equipped with two gigabit  
expansion ports, providing for the installation of one or two expansion mod-  
ules. These ports provide links to high-speed network segments or individual  
workstations at speeds of up to 1000Mbps (Gigabit Ethernet).  
• Keep cabling away from sources of electrical noise, power lines, and  
fluorescent lighting fixtures.  
• Position the GigaSwitch away from water and moisture sources.  
To establish a Gigabit Ethernet connection, you will need to install a SX or  
TX Gigabit expansion module and use fiber optic cabling. for more informa-  
tion on fiber optic cabling, refer to the Fiber Optic Cabling section on page  
79.  
• To ensure adequate air flow around the GigaSwitch, be sure to provide a  
minimum of one inch (25mm) clearance.  
• Do not stack free-standing GigaSwitches more than four units high.  
The Console Port  
The 10/100 Managed 24-Port GigaSwitch is equipped with a serial port  
labeled CONSOLE (located on the rear of the switch) that allows you to con-  
nect to a computer (for configuration purposes) using the provided serial cable.

6. When you finish, press the Esc key. A prompt will ask whether you want  
to upgrade your software now.  
RMON is an abbreviation for the Remote Monitoring MIB (Management  
Information Base). RMON is a system defined by the Internet Engineering  
Task Force (IETF) document RFC 1757, which defines how networks can be  
monitored remotely. RMONs typically consist of two components: an RMON  
probe and a management workstation:  
7. Highlight Yes and press Enter to upgrade the software now. Press the Esc  
key or highlight No and press Enter to not upgrade at this time.  
• The RMON probe is an intelligent device or software agent that continually  
collects statistics about a LAN segment or VLAN. The RMON probe trans-  
fers the collected data to a management workstation on request or when a  
pre-defined threshold is reached.  
• The management workstation collects the statistics that the RMON probe  
gathers The workstation can reside on the same network as the probe, or it  
can have an in-band or out-of-band connection to the probe.  
The GigaSwitch provides RMON capabilities that allow network administra-  
tors to set parameters and view statistical counters defined in MIB-II, Bridge  
MIB, and RMON MIB. RMON activities are performed at a Network  
Management Station running an SNMP network management application  
with graphical user interface.  
SNMP Agent and MIB-2 (RFC1213)  
The SNMP Agent running on the switch manager CPU is responsible  
for:  
• Retrieving MIB counters from various layers of software modules according  
to the SNMP GET/GET NEXT frame messages.  
• Setting MIB variables according to the SNMP SET frame message.  
• Generating an SNMP TRAP frame message to the Network Management  
Station if the threshold of a certain MIB counter is reached or if other trap  
conditions (see next page) are met:

• Warm start  
BRIDGE GROUPS SUPPORTED  
• Cold start  
The GigaSwitch supports the following four groups of Bridge MIB  
(RFC1493):  
• Link up  
• Link down  
• Authentication failure  
• Rising alarm  
• Falling alarm  
• Topology change  
The dot1dBase Group a mandatory group that contains the objects appli-  
cable to all types of bridges.  
The dot1dStp Group contains the objects that denote the bridge's state,  
with respect to the Spanning Tree Protocol. If a node does not implement  
the Spanning Tree Protocol, this group will not be implemented. This group  
is applicable to any transparent only, source route, or SRT bridge that imple-  
ments the Spanning Tree Protocol.  
MIB-2 defines a set of manageable objects in various layers of the TCP/IP  
protocol suites. MIB-2 covers all manageable objects from layer 1 to layer 4  
and, as a result, is the major SNMP MIB supported by all vendors in the net-  
working industry. The GigaSwitch supports a complete implementation of  
SNMP Agent and MIB-2.  
The dot1dTp Group contains objects that describe the entity's transparent  
bridging status. This group is applicable to transparent operation only and  
SRT bridges.  
RMON MIB (RFC 1757) and Bridge MIB (RFC 1493)  
The GigaSwitch provides hardware-based RMON counters in the switch  
chipset. The switch manager CPU polls these counters periodically to collect  
the statistics in a format that complies with the RMON MIB definition.  
The dot1dStatic Group contains objects that describe the entity's destina-  
tion-address filtering status. This group is applicable to any type of bridge  
which performs destination-address filtering.  
RMON GROUPS SUPPORTED  
The GigaSwitch supports the following RMON MIB groups defined in  
RFC1757:  
• RMON Statistics Group maintains utilization and error statistics for the  
switch port being monitored.  
• RMON History Group gathers and stores periodic statistical samples from  
the previous Statistics Group.  
• RMON Alarm Group allows a network administrator to define alarm  
thresholds for any MIB variable. An alarm can be associated with Low  
Threshold, High Threshold, or both. A trigger can trigger an alarm when the  
value of a specific MIB variable exceeds a threshold, falls below a thresh-  
old, or exceeds or falls below a threshold.  
• RMON Event Group allows a network administrator to define actions  
based on alarms. SNMP Traps are generated when RMON Alarms are trig-  
gered. The action taken in the Network Management Station depends on the  
specific network management application.

About Gigabit Ethernet  
Appendix  
Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times  
faster than 100Mbps Fast Ethernet, but it still integrates seamlessly with  
100Mbps Fast Ethernet hardware. Users can connect Gigabit Ethernet hard-  
ware with either fiber optic cabling or copper Category 5 cabling, with fiber  
optics more suited for network backbones. As the new Gigabit standard grad-  
ually integrates into existing networks, current computer applications will  
enjoy faster access time for network data, hardware, and Internet connections.  
About Fast Ethernet  
As the demand for desktop video, multimedia development, imaging, and  
other speed-intensive applications continues to rise, the need for high per-  
formance, fault tolerant LAN technology will become more critical.  
Standard Ethernet, which has been the most popular networking technology  
to date with a maximum data throughput of 10Mbps (Megabits per second),  
is becoming insufficient to handle the latest video, multimedia, and other  
speed-intensive client/server LAN applications.  
Fiber Optic Cabling  
Among the solutions to the problem of network speed, Fast Ethernet has  
emerged as the most viable and economical. Capable of sending and receiv-  
ing data at 100Mbps, it is more than fast enough to handle even the most  
demanding video and other real-time applications.  
Fiber optic cabling is made from flexible, optically efficient strands of glass  
and coated with a layer of rubber tubing, fiber optics use photons of light  
instead of electrons to send and receive data. Although fiber is physically  
capable of carrying tetrabits of data per second, the signaling hardware cur-  
rently on the market can handle no more than a few gigabits of data per sec-  
ond.  
Although there are a number of different competing Fast Ethernet implemen-  
tations, 100BaseTX is by far the most popular. Operating on two pairs of  
Category 5 unshielded twisted-pair (UTP) cabling, 100BaseTX supports high  
speed signaling and is relatively inexpensive. Because it uses four wires for  
data transmission and the same packet format, packet length, error control,  
and management information as 10BaseT, 100BaseTX can be made to com-  
municate with slower 10BaseT equipment when routed through a switch.  
Fiber cables come in different with two main connector types. The most com-  
monly used fiber optic cable is multi-mode fiber cable (MMF), with a 62.5  
micron fiber optic core. Single-mode fiber cabling is somewhat more effi-  
cient than multi-mode but far more expensive, due to its smaller optic core  
that helps retain the intensity of traveling light signals. A fiber connection  
always require two fiber cables: one transmits data, and the other receives it.  
This backwards compatibility is one of 100BaseTX's major advantages over  
other forms of Fast Ethernet; it allows critical, speed-dependent network seg-  
ments to be upgraded to 100BaseTX speeds as needed without re-wiring,  
refitting, and retraining an entire site. Networks can now mix both slow and  
fast network segments for different users or departments. Publishing, R&D,  
video, multimedia, or accounting departments can enjoy a 100Mbps pace,  
while other corporate segments can operate at slower and more affordable  
10Mbps speeds.  
Each fiber optic cable is tipped with a connector that fits into a fiber port on  
a network adapter, hub, or switch. In the U. S., most cables use a square SC  
connector that slides and locks into place when plugged into a port or con-  
nected to another cable. In Europe, the round ST connector is more prevalent.

Crimping Your Own Network Cables  
Twisted-Pair Cabling  
There are different grades, or categories, of twisted-pair cabling. Category 5  
is the most reliable and is highly recommended. Category 3 is a good second  
choice. Straight-through cables are used for connecting computers to a hub.  
Crossover cables are used for connecting a hub to another hub (there is an  
exception: some hubs have a built-in uplink port that is crossed internally,  
which allows you to link or connect hubs together with a straight-through  
cable instead).  
You can buy pre-made Category 5  
cabling, or cut and crimp your own.  
Category 5 cables can be purchased  
or crimped as either straight-through  
or crossover cables. A Category 5  
cable has 8 thin, color-coded wires  
inside that run from one end of the  
cable to the other. All 8 wires are  
used. In a straight-through cable,  
wires 1, 2, 3, and 6 at one end of the  
cable are also wires 1, 2, 3, and 6 at  
the other end. In a crossover cable,  
the order of the wires change from  
one end to the other: wire 1 becomes  
3, and 2 becomes 6. See the diagrams  
on the next page for  
more detailed informa-  
tion on straight-through  
and crossover cabling.  
To determine which wire is wire number 1, hold the  
cable so that the end of the plastic RJ-45 tip (the part  
that goes into a wall jack first) is facing away from  
you. Face the clip down so that the copper side faces up  
(the springy clip will now be parallel to the  
floor).When looking down on the copper side, wire 1  
will be on the far left.
