Figure 27 Example Rack Installation: ETERNUS AX4100, ETERNUS HX6100
• When determining the rack-mounting layout of each shelf and power distribution unit, consider the length
of each cord. For example, if the ETERNUS AX/HX is installed at the top of a 2000 mm rack and a 4 m power
cord is used, the surplus length of the power cord at the bottom of a rack should be about 2 m.
• If the ETERNUS AX/HX is installed at the bottom of a rack, a space for the surplus of cables may not be avail-
able in some racks, preventing the ETERNUS AX/HX from being pulled out when maintenance work is
required. In this case, secure a space of 1U or more at the bottom when installing the ETERNUS AX/HX.
• If drive shelves are to be added in the future, securing sufficient space for power distribution units in the bot-
tom of the rack is recommended.
• If devices are installed above and below the ETERNUS AX/HX and there is a difference in depth of 100 mm or
more, leave a space of 1U above the ETERNUS AX/HX so the rear of the unit can be easily accessed.
