NTRODUCTION
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
Plug-and-play

NSTALLING THE SWITCH
Before installing the switch, verify that you have all the items listed under “Package Contents.” Note that the switch can be installed on any suitably large flat surface or in a standard EIA 19-inch rack.
Package Contents
The Switch 10/100 includes:
LNES24 Fast Ethernet Switch
Four rubber foot pads
Rack-mount bracket kit
Appropriate AC power cord
This User Guide
Selecting a Site
Be sure to follow the site selection guidelines below when choosing a location:
Select a suitable location for the switch: o It should be accessible for installing, cabling and maintaining the
switch.
o The temperature and humidity should be within the ranges listed
in the specifications.
o The status LEDs should be clearly visible.
o There should be adequate space (approximately two inches) on all
sides for proper air flow.
4
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.
5
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.

ROUBLESHOOTING
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 Check for loose connections. o Check the power outlet by using it for another device. o 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 Be sure the network cable is connected to both devices. o 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 Check the network card and cable connections for defects. o 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.
