This model incorporates one BCU, one RP, and one POW; the BCU consists of one
RM and one CSW, and is physically packaged in one RM-CPU module and one
RM-IO module. One BCU for redundancy, up to two additional RPs, and one POW
for redundancy can be installed as options, independently of one another. Since
one RP can handle up to two NIFs, a total of six NIFs can be installed on this
model. The BCU redundancy is made available by mounting the optional
RM-CPU and RM-IO modules in the RM-CPU1 and RM-IO1 slots; otherwise, only
the base RM-CPU and RM-IO modules are mounted in the RM-CPU0 and RM-IO0
slots. Similarly, the power supply redundancy is made available by mounting the
optional POW in the POW1 slot; otherwise, only the base POW is mounted in the
POW0 slot.
