Active and Standby Designations
Typically, the first CPM card installed in a 7950 XRS chassis assumes the role as active,
regardless of being inserted in Slot A or B. The next CPM installed in the same chassis then
assumes the role as the standby CPM. If two CPM are inserted simultaneously (or almost
simultaneously) and are booting at the same time, then preference is given to the CPM installed in
Slot A.
If only one CPM is installed in a redundant router device, then
it
becomes the active CPM
regardless of the slot it is installed in.
StatusThe Status LED on the second CPM faceplate is lit amber to indicate the standby
designation. To visually determine the active and standby designations, see the LED displays on
the CPM front panel as shown in
Figure 11: CPM LEDs
