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

Front Panel LEDs  
The front panel of the switch provides a link status LED for each RJ-45  
port. In addition, the front panel also contains status LEDs for  
“at-a-glance” system monitoring. The following table details the functions  
of the various indicators:

INSTALLING 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
o
The status LEDs should be clearly visible.  
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.

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.
