Attention: To avoid potential equipment damage during transport and subsequent loss of data,
see Procedure: Transporting a 5U 92-drive expansion enclosure. The procedure describes what to
do for the following situations.
• When you are powering off a 92F, 92G, or an A9F 5U expansion enclosure because you intend to
transport it to another location
• When you intend to move a rack that contains a 92F, 92G, or an A9F 5U expansion enclosure
The procedure describes how to remove each drive from the 5U enclosure and transport the
enclosure. Removing the drives prevents damage to the drives and makes the lighter enclosure
easier to move.
Warning: Some racks will not provide sufficient space to close the rear door. 2077-92G, 2077-
A9G and 2078-92G, 2078-A9G model enclosures need 968 mm from the rack front post to the
back of the cable management arm (CMA). In addition, allow 905 mm from the front post to the
back of the enclosure. To allow space for the power cables, provide 60 - 70 mm from the back of
the enclosure.
Figure 84 on page 93 shows the rack space requirements for the 5U ( 2077/2078-24G or 2077/2078-
AFG , 2077-92G, 2077-A9G and 2078-92G, 2078-A9G ) expansion enclosures.
