NOTE: Direct Connect BackPacks do not provide Sparing or Admin switching
capabilities, and thus do not have Admin or Spare ports. If you use a Direct
Connect BackPack in a Control Chain, connect the CONTROL IN and
CONTROL OUT ports, and jumper the Spare and Admin daisy chains over
the DCBP.
5. Daisy-chain the ADMIN IN port on one Cage to the ADMIN OUT port on the next
Cage using the yellow daisy-chain cable provided. Connect the remaining ADMIN
OUT port to the Admin C/Port.
6. Daisy-chain the SPARE IN port on one Cage to the SPARE OUT port on the next
Cage using the red daisy-chain cable provided. Connect the remaining SPARE IN
port to the Spare Blade’s C/PORT port.
Mixed-Mode BackPack Cabling
Mixed-mode cabling is the attachment of R4300-equipped Cages to Cages with BSBPs
or DCBPs. The recommended practice is to use one or more R4300s for Primary and
auto-negotiated control. One or more RMMs need to be connected to Ethernet to allow
auto-negotiation and control failover. Figure 29 shows an example of this.
