GR2000 Installation Guide
GR2000-20H
This model incorporates one BCU, one RP, and three POWs; the BCU consists of
one RM physically packaged in one RM-CPU module and one RM-IO module, and
one CSW physically packaged in one master CSW module (CSW-M) and one sub
CSW module (CSW-S). One BCU for redundancy, up to nine additional RPs, and
three POWs for redundancy can be installed as options, independently of one
another. Since one RP can handle up to two NIFs, a total of twenty NIFs can be
installed on this model. The BCU redundancy is made available by mounting the
optional RM-CPU, RM-IO, CSW-M, and CSW-S modules in the RM-CPU1,
RM-IO1, CSW-1M, and CSW-1S slots; otherwise, only the base RM-CPU, RM-IO,
CSW-M, and CSW-S modules are mounted in the RM-CPU0, RM-IO0, CSW-0M,
and CSW-0S slots.
