Removing a TXP-CIP

328
The TXP-CIPs are located to the right of the TXP-F2S SIB card cage, below the TXP-CBs
and Routing Engines.
Each redundant TXP-CIP is hot-removable and hot-insertable. It weighs approximately
5.3 lb (2.4 kg). When the TXP-CIP is removed, the backup TXP-CIP provides redundant
connections to the active host subsystem in the TX Matrix Plus router and the active
LCC-CBs in the T1600 routers.
NOTE: If you are replacing a TXP-CIP in an operational TX Matrix Plus router,
the TX Matrix Plus router and each T1600 router in the routing matrix must
have redundant host subsystems.
