Active And Standby Designations - Alcatel-Lucent 7710 SR Configuration Manual

Active and Standby Designations

Typically, the first CFM installed in a 7710 SR-Series chassis assumes the role as active,
regardless of being inserted in Slot A or B. The next CFM installed in the same chassis then
assumes the role as the standby CFM. If two CFMs are inserted simultaneously (or almost
simultaneously) and are booting at the same time, then preference is given to the CFM installed in
Slot A.
If only one CFM is installed in a 7710 SR-Series router, then
regardless of the slot it is installed in.
To visually determine the active and standby designations, the MS/CTL LED on the faceplate is lit
green (steady) to indicate the active designation. The MS/CTL LED on the second CFM faceplate
is flashing greeen to indicate the standby designation.
The following output shows that the CFM installed in Slot A is acting as the active CFM and the
CFM installed in Slot B is acting as the standby.
