ClearCube R Series Pentium 4 - Manual (Page 72)

62 • Cage and Blade Installation ClearCube Product Manual and Installation Guide
NOTE: With a Blade Switching BackPack as Primary, no other Cages in the Control
Chain can serve as Secondary, because Secondary mode is not supported
on the RMC.
Remote Management Card Configuration
Control Chain Auto-Negotiation
Two types of Remote Management Cards may be present in your network:
• RMC
• RMM
The RMC in Blade Switching (BSBP) and Direct Connect (DCBP) BackPacks is not
capable of auto-negotiation. A BCBP or DCBP with an RMC installed is always the
Primary in the Control Chain. RMCs can be installed only in BCBPs and DCBPs and
RMMs can only be installed in R4300 BackPacks. A BSBP without an RMC installed
can perform C/Port Switching, Admin Switching, and Sparing under the control of an
RMC or an RMM.
