This model incorporates one BCU, one RP, and two POWs; 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 four additional RPs, and two
POWs for redundancy can be installed as options, independently of one another.
Since one RP can handle up to two NIFs, a total of ten 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.
The front view when PS is mounted with an AC input unit is shown in Figure
2-35, the front appearance view of GR2000-10H (AC input), and the rear view in
Figure 2-36, the rear appearance view of GR200-10H(AC input).
