Preparing the Rack (System or Expansion)
1.Find the two support rails (5 in Figure 1 on page 4) that are supplied with the 2104.
2.The 2104 Model DU3 is three Electronics Industries Association (EIA) units high. Using the preinstallation planning information, or other relevant information, determine where you are going to locate the 2104 Model DU3 in the rack.
Notes:
v If you are installing the 2104 Model DU3 into an empty rack, install it into the lowest available position so that the rack does not become unstable.
vIf you are installing more than one 2104 Model DU3 into the rack, start at the lowest available position, and work upward.
vYou might need to remove the rack power distribution unit before you install the support rails (see the Installation and Service Guide, or equivalent, for the rack).
3.Refer to the EIA markings on the rack and decide where you are going to install the support rails. If appropriate, allow for possible future installation of other disk enclosures.
