INTRODUCTION
The LNES24 is a 24-port Fast Ethernet switch. The 10BASE-T/100BASE-TX
ports deliver dedicated 10/100 Mbps links to each attached LAN segment – all
with conventional cabling and adapters.
Auto-negotiation is used to select the optimal communication mode for
each connection. Auto-sensing is used to select the optimal transmission
speed for each connection. With store-and-forward switching and flow
control, maximum data integrity is always maintained, even under heavy
loading. Easy installation and reliability make this plug-and-play switch an
ideal choice for smooth Fast Ethernet integration.
Features and Benefits
•
Auto-negotiation of half or full duplex, and auto-sensing of
transmission speed, on all ports
•
Auto configuration for MDI/MDI-X cable connection allows
connections to servers, workstations, hubs or switches to be made
with straight-through cabling
•
ANSI/IEEE 802.3u compliance ensures compatibility with
standards-based hubs, switches and cards from any vendor
•
•
Store-and-forward switching ensures error-free transmission
Half- and full-duplex flow control prevents packets from being
dropped under heavy loading

Make sure twisted-pair cable is always routed away from power lines,
fluorescent lighting fixtures and other sources of electrical
interference such as radios, transmitters, etc.
Make sure that a properly grounded power outlet is within 2.44 meters
(8 feet) of the switch and is powered from an independent circuit
breaker. As with any equipment, using a filter or surge suppressor is
recommended.
Instructions
1. Positioning the Switch: For desktop or shelf mounting, attach the
four adhesive foot pads to the bottom of the switch. For rack- mounting,
attach the mounting brackets on both sides of the screws provided, and
install the switch in the rack.
2. Applying Power: Plug one end of the power adapter into the power
receptacle at back of the switch, and the other end into an appropriate
electrical outlet. Check the Power LED to be sure power is on.
Note: It is not necessary to power off the switch before connecting or
disconnecting any UTP cables, as these actions will not disrupt
the operation of other devices attached to the switch.
3. Connecting PCs: Connect each PC to an RJ-45 port on the switch
using Category 5 or 5e shielded or unshielded twisted-pair (UTP or
STP) cable, maximum length 100 meters (328 ft). LNES24 will support
up to 24 PCs. All ports on the switch support automatic MDI/MDI-X
operation, so you can use straight-through cables for all network
connections to PCs or servers, or to other switches or hubs.
Note: If an attached device does not support auto-negotiation, the data
rate will be sensed automatically and the communication mode
will default to half duplex.

4. Cascading Switches and Other Network Devices: All the
ports on the switch support automatic MDI/MDI-X configuration for cable
connections. This allows you to use straight-through cable to connect
to other switches or hubs from any port on the switch. No crossover
cables or other device settings are needed. See the Cable
Specifications.
Caution: Do not plug a phone jack connector into any RJ-45 port. This
the switch. Instead, use only twisted-pair cables
with RJ-45 connectors that conform with FCC standards.

TROUBLESHOOTING
Diagnosing Switch Indicators
1. Symptom
Power LED does not light after power on.
Probable Causes
o
AC power cord may be defective.
Possible Solutions
o
o
o
Check for loose connections.
Check the power outlet by using it for another device.
Replace the AC power cord.
2. Symptom
Link LED does not light after connection is made.
Probable Causes
o
Switch port, network card or cable may be defective.
Possible Solutions
o
Check that the switch and attached device are both powered
on.
o
o
Be sure the network cable is connected to both devices.
Verify that Category 5 or better cable is used for 10/100
Mbps connections and that the length of any cable does not
exceed 100 meters (328 feet).
o
o
Check the network card and cable connections for defects.
Replace the defective card or cable if necessary.

Caution:
DO NOT plug a phone jack connector into any RJ-45 port.
Use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for
RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps
connections or 100-ohm Category 5 or better cable for 100 Mbps
connections. Also be sure that the length of any twisted-pair connection
does not exceed 100 meters (328 feet).
Because all ports on this switch support automatic MDI/MDI-X
operation, you can use straight-through cables for all network connections
to PCs or servers, or to other switches or hubs. In straight-through cable,
pins 1, 2, 3, and 6, at one end of the cable, are connected straight through
to pins 1, 2, 3 and 6 at the other end of the cable.
