Please read the following safety information carefully before installing the Switch: WARNING: Installation and removal of the unit must be carried out by qualified personnel only. • This guide is intended for use by network administrators who are responsible for setting up and installing network equipment; consequently it assumes a basic working knowledge of LANs (Local Area Networks). • The unit must be connected to an earthed (grounded) outlet to comply with international safety standards.
France and Peru only This unit cannot be powered from IT. supplies. If your supplies are of IT type, this unit must be powered by 230 V (2P+T) via an isolation transformer ratio 1:1, with the secondary connection point labelled Neutral, connected directly to earth (ground). †Impédance à la terre Power Cord Set U.S.A. and Canada The cord set must be UL-approved and CSA certified. The minimum specifications for the flexible cord are: - No. 18 AWG - not longer than 2 meters, or 16 AWG.
Warnings and Cautionary Messages Warning: This product does not contain any serviceable user parts. Warning: Installation and removal of the unit must be carried out by qualified personnel only. Warning: When connecting this device to a power outlet, connect the field ground lead on the tri-pole power plug to a valid earth ground line to prevent electrical hazards. Caution: Wear an anti-static wrist strap or take other suitable measures to prevent electrostatic discharge when handling this equipment.

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.
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: Port and Switch Status LEDs LED Condition Status Power On Green The switch is receiving power. On The port has established a valid network connection. Flashing Traffic is passing through the port.
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.
• • 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.
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.
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 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.
