Chapter 2—Site Requirements Physical Requirements
February 2019 Site Preparation Guide—Spectra T950B Library
21
Data center floors may require reinforcement to hold the library’s weight.
Check your site’s flooring for load-bearing specifications.
Weight-Distribution Plates If you would like to install the library on
weight-distributing plates, Spectra Logic recommends steel plates with the
minimum dimensions of 36 x 30 x 0.25 inches (91.4 x 76.2 x 0.6 cm). Plates
should be placed under the feet at the front and back of each frame
junction and under the outer feet of the right-most and left-most frames of
a multi-frame library.
Note: After determining the positions for the plates, attach them to the
floor to prevent them from moving as you roll the frames into place.
Flooring Type The floor where the library is to be installed must be level, and
must be hard flooring, such as cement or tile—do not install the library on
carpeting. This requirement is particularly important when installing a multi-
frame library, because all frames must be precisely aligned. Carpeting also
increases the risk of static discharge when operating the library.
A small amount of floor unevenness can be compensated for using the
levelers on each library frame.
Space Requirements
Library Frames Placement
The bulk TAP, if present, must always be the left-most frame as viewed
from the front of the library. The main frame must be positioned as the
left-most frame or the frame immediately to the right of the bulk TAP. Up
to four drive expansion frames can be located immediately to the right of
the main frame. Media frames can be located to the right of the main frame
and any drive frames. A maximum of eight frames is allowed.
Spectra Logic is not responsible for damage caused to the library or its
surroundings if the floor is not adequately reinforced. Inadequate floor
reinforcement can allow the library to sag, causing misalignment of the frames and
robotic motion failures.
The library must be installed on a level, hard-surfaced floor such as cement or tile.
