LEDs and What They Mean
The following tables outline how the Switch, Uplink Module and PIC LEDs
report faults and operational activities. Uplink Modules, NSMs, and PICs are
expansion options and can be purchased separately. Contact an authorised
Allied Telesis distributer or reseller, or visit from www.alliedtelesis.com for
more information on purchasing expansion options.
Switch LEDs
These LEDs are on the front or rear panels of Rapier Switches.
