NSTALLING THE
SF/CPM
Install the SF/CPM module before installing IOMs. Install SF/CPMs only in lower slots A or B.
Typically, the first SF/CPM module installed in an 7450 ESS-7 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 only one CPM is installed in the 7450 ESS-7 chassis, it
becomes the active CPM regardless of the slot it is installed in.
When the active CPM is removed for replacement or fails, the standby becomes the active CPM. If
two CPMs are inserted simultaneously (or almost simultaneously) and are booting at the same
time, then preference is given to the CPM installed in Slot A.
NOTE : Each SF/CPM module has two ejector levers which seat and release the card from the
backplane connectors. During installation, the ejector levers must be positioned inward and then
rotated outward to lock into place. The ejector levers must remain in the locked position while the
card is installed in the chassis.
