The Cable Tray (the installation kit is supplied with the chassis) should
be installed on the top of the chassis front to enable convenient routing
of cables connecting to power source(s), outdoor unit(s) and other
equipment.
To enable power source and/or Power Interface Unit 1+1 redundancy
two PIU modules can be installed in the designated slots. If a single PIU
module is used, it can be inserted into either one of the two available
slots.
The number of installed PSU modules depends on the specific
configuration (number of AUs) and NPU redundancy scheme (refer to
Table 2-8 and Table 2-9 on page 2-18). If less than 4 PSU modules are
used, they can be installed in any of the designated slots.
The NPU should be installed in slot number 5 (slot numbers are marked
on the Cable Guide). Slot 6 is reserved for a future redundant NPU.
Slots 1-4 and 7-9 can hold up to six AU-IDU modules.
Unused slots should remain covered until required.
