v A minimum rack opening width of 500 mm (19.69 in.) for a depth of 330 mm (12.99 in.) is needed
behind the installed system for maintenance and service. The depth can extend beyond the rack rear
door. The 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME server node needs at least 254 mm (10 in.)
of depth within the rack from the rear rack mount flange to the frame line. This space is necessary for
cable management.
Note:
Power distribution units (PDUs) should be mounted horizontally in the U space so that the
additional width of the rack can also be used for the 9080-MHE and 9119-MHE or 9080-MME and
9119-MME system cable management. If PDUs are mounted vertically in the side pockets, extra space
is required either 2U below the server drawer or through an extra 127 mm (5 in.) of depth within the
rack from the rear rack mount flange to the frame line.
