Installing a Rack Mount Library

This section explains how to install an M1500 or M2500 in a standard 19-inch
rack.
Determining the
Position of the
Shelves in the Rack
0
Before starting the rack mount installation:
1
Determine the proper position of the shelves in the rack:
• The rack is measured in rack mount units. Each unit is called a “U,”
and is equal to 1.75 inches (44.45 millimeters). When you look at the
rack rails you will notice that the holes are divided into groups of
three, with each group separated by a slightly smaller space. Each
group of three equally spaced holes is one U (see figure 3 ).
• An M1500 uses 4U of vertical space. The M1500 rack mount shelves
must be installed in a full U position (the bottom of the rack mount
shelf must be aligned with the bottom of a U) (see figure 4 ).
• An M2500 uses 13.5U of vertical space. The M2500 rack mount
shelves can be installed in either a full U or a half U position (the
bottom of the rack mount shelf may be aligned with either the bottom
or the middle of a U) (see figure 5 ).
• The StackLink mounting hardware uses 1U of vertical space at the
top of the rack, and either 1U or .5U at the bottom of the rack (see the
Tandberg M-Series StackLink Installation Instructions , PN T6423049, for
more information).
2
Mark the desired shelf position on the rack rails.
Note:
The procedures in this section assume that you have already
unpacked the library. If you have not, do so now, referring to the
Tandberg M1500 Unpacking Instructions (PN T6421035) or Tandberg
M2500 Unpacking Instructions (PN T6423047).
Caution: Take rack stability into account when determining
where to place the library in the rack.
