Hub Installation
 To install LRSI-F-14:
1. Insert the LRSI-F-14 module into the upper section of the LRS-24F chassis
above the ASMi-52CD module, or into the back section of LRS-24B.
2. Fasten the screws to secure the module to the LRS-24 frame for proper
grounding of the module panel.
Connecting the LRSI-F-14 Module
Table F-3 lists the pinout of the DCE-1/DCE-2 connector of the LRSI-F-14
interface module.
Table F-3. DCE-1/DCE-2 Connector Pinout
Pin ID Function Direction
1 Tx+ Transmit – positive lead Output
2 Tx– Transmit – negative lead Output
3 Rx+ Receive – positive lead Input
4, 5 – Not connected –
6 Rx– Receive – negative lead Input
7, 8 – Not connected –
When connecting LRSI-F-14 to the LAN, use a cross cable for connection to a port
that does not implement the crossover function internally. Otherwise, use a
straight cable.
Hubs usually do implement the crossover function internally while NICs and other
devices do not.
LED Indicators
Table F-4 lists the IR-ETH/QN rear panel LED indicators and describes their
functions.
