At least one power cord must be used for operation of the HP MCS G2. The second cord can be
connected to a redundant AC power bus to improve system availability. In this case, the transfer
switch assembly of the HP MCS G2 provides switchover to the active power bus in the event of power
source failures or accidentally tripped circuit breakers.
Note
The power cords are 4.5 meters (14.7 feet) long. After the cords are
connected to the HP MCS G2 and routed down the rear of the cooling
unit, approximately 2.5 meters (8.2 feet) will be left to connect to the
power source.
When using only a single (primary) source for power, the AC power cord is connected to the left-most
C20 receptacle (when viewed from the rear of the cabinet), as shown in figure 14.
