Installing The Cable Management Bracket; Installing The Releasable Cable Ties For The Infiniband Cables - HP Cluster Platform Hardware Kits v2010 Installation Manual

3 Installing the Cable Management Bracket

The location of the cable management bracket depends on the rack position occupied by the HP
BladeSystem c-Class enclosure. The InfiniBand switch might be installed in any or all of the
interconnect module bays identified in
3.1 Installing the Cable Management Bracket
Use the following procedure to install the HP BladeSystem c-Class enclosure cable management
bracket:
Caution:
When performing the installation procedure, extend only one c-Class enclosure no more than a
few inches from the rack at any time. Ensure that the rack is stable before you begin the installation
procedure.
Note:
One cable management kit is required for each InfiniBand switch installed in the rear of the c-Class
enclosure.
1. Starting from the lowest bracket location, and using the fastener locations that you identified
and marked in
2. Hook the bracket onto the square cutouts in the rack column.
3. Fasten the bracket to the rear rack columns by using two M6 pan-head screws and tighten
them to the specified torque.
4. If more than one bracket is required, repeat Step 1.
5. Slide the c-Class enclosure back into the rack and secure it at the front of the rack as specified
in the installation instructions for the enclosure.
6. If necessary, attach the second bracket once the first switch (lowest switch in the c7000
enclosure) is cabled and tie-wrapped.
Note:
HP recommends that you only install the cable management bracket for the lowest InfiniBand switch
in the c-Class enclosure and complete the cable installation. Doing so makes it easier to install the
releasable cable ties for each of the InfiniBand cables. Once the releasable cable ties are installed
for the InfiniBand cables coming from the switch installed in the lowest interconnect module bay,
you must install the next cable management bracket and releasable cable ties for the next InfiniBand
switch. It is necessary to complete the installation for the lowest bracket first because there is not
enough space between the two brackets to secure the releasable cable ties for the lower bracket
when two or more brackets must be installed.
