When configured for side-by-side redundancy, The XGLC is referenced only by the upper slot number (17 through 23,
26 through 33); the lower slot number is not recognized. All other configuration commands work as if the side-by-side

Halting Cards
Packet processing cards or line cards that are in either the active or standby modes can be halted. Halting these cards
