Collocating Cisco Units in the Same Rack
Different Cisco units, for example, MGX 8220 shelf, BPX switch, and INS, can be collocated in the
same rack or cabinet. When this is done, however, the inclusion and positioning of MGX 8220
power, cooling, booster, plenum, and spacer modules relative to the MGX 8220 shelf must be the
same as those when MGX 8220 shelf is used in a dedicated rack. Some examples of multi-system
configurations are shown in Figure7-8.
The configuration on the left includes a BPX switch, redundant INS’s and two MGX 8220 shelves.
The center includes a BPX switch and three MGX 8220 shelves. On the right is a six shelf DC
arrangement.
In multi-system racks, the BPX switch, if included, should be mounted at the bottom.
The MGX 8220 shelves including the power, cooling, booster, plenum, and spacer should be
mounted in the proper order at the top to allow for growth.
