sideways to allow the strap to be held in a position that will not interfere with the removal of the number

Colocating Cisco Units in the Same Rack
Different Cisco units, for example, MGX 8220 shelf, BPX switch, and ESP, can be colocated 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 the MGX 8220 shelf is used in a dedicated rack.
Some examples of multisystem configurations are shown in Figure 7-8. The configuration on the left
includes a BPX switch, redundant ESPs and two MGX 8220 shelves. The configuration on the right
includes a BPX switch and three MGX 8220 shelves.
In multisystem 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.
