Condition

Status

 

 

 

 

 

 

Stack Link

Green

Uplink and downlink operating normally.

 

 

 

Flashing Green

Uplink has failed.

 

 

 

Flashing Amber

Downlink has failed.

 

 

 

Off

No stacking link present.

 

 

 

 

 

Module

Green

An expansion module (LGB6001C) is installed

 

 

 

 

and operating normally.

 

 

 

Amber

An expansion module is installed but has failed.

 

 

 

Off

There is no module installed.

 

 

 

 

 

Stack ID

1-8

Indicates the switch stack ID.

 

 

 

 

The Master unit is numbered 1. (Note that If the

 

 

 

 

master unit fails and a backup unit takes over, the

 

 

 

 

stack IDs do not change.)

 

 

 

 

Slave units are numbered 2-8.

 

 

 

Off

In standalone mode.

 

 

 

 

 

 

OPTIONAL REDUNDANT POWER SUPPLY

The switch supports an optional Redundant Power Supply (RPS), that can supply power to the switch in the event the internal power supply fails.

POWER SUPPLY SOCKET

There are two power sockets on the rear panel of each switch. The standard power socket is for the AC power cord. The socket labeled “RPS” is for the optional Redundant Power Supply (RPS).
