Managing Power Cords - Quantum Scalar i500 User Manual

Managing Power Cords

Power cord management is important especially for the larger, expanded library configurations. A 41U
library with redundant power, the maximum configuration, may contain as many as 10 power supply units
with 10 power cords to manage.
To organize power cords on the rear of the library, mount a black hook-and-loop fastener to each module
and then secure the power cords with the fastener.
Power cords and power cord hook-and-loop fasteners that are shipped with the library are black in color.
You can apply the following procedure to any library that contains at least one expansion module.
To secure a power cord to the library frame:
1 Facing the rear of the library, locate a specific hole that is drilled into the back of the expansion module
for the hook-and-loop fastener. This hole is located on the rear of the library, about three inches from
the top of the expansion module near the right side of the library chassis. Refer to the illustration below
to locate this hole.
If your module chassis does not have the drilled hole, use an M5 thumbscrew
Note
to attach the black hook-and-loop fastener to the nearest available M5
threaded hole on the lower right of any module chassis.
2 Insert a push rivet into the rivet hole on the black hook-and-loop fastener. The head of the rivet should
be on the same side of the fastener as the plastic loop.
3 Firmly press the push rivet through the hole in the expansion module described above. The hook-and-
loop fastener should now be secured to the library chassis.
4 Plug the power cord into a power supply unit closest to the hook-and-loop fastener.
5 Determine how much cord length you need to reach and easily plug into the AC power source. Do not
plug the cord into power source until you are ready to power on the library.
6 If there is excess power cord, loop the excess cord into a bundle in the shape of a figure-eight. The
bundle should be small enough to hold comfortably with one hand, or about eight inches in length.
7 Wrap the bundle with the hook-and-loop fastener. Thread the strap through the plastic loop and tighten
the strap around the bundled cord. Secure the strap by pressing it down.
The power cord is now secured to the expansion module. Repeat these steps to secure other power cords,
if necessary. Bundle adjacent power cords together using the same hook-and-loop fastener.
Once complete, power cord management for a 41U library should look similar to
