Tab Mount Cable Management Bracket Installation Guide

6. After aligning the strap, tighten the screw to it
s specified torque.
Repeat the installation procedure for subsequent bracket kits, using a marker pen
or masking tape to transfer the correct horizontal location of the strap to each
bracket.
When all brackets are installed, consult the ca
bling instructions for your cluster
model before starting the cabling procedu
re described in Section 2.2. (See
Section 1.2 for the location of the cluste
r documentation.)
2.2 Securing Cables Using the Straps
Use the following procedure to secure a cable:
1. Connect the cable to the port in the PCI adapter and secure it mechanically by
its clips, screws, or clamps.
2. Route the cable over the strap, loop the strap through its D-ring, and secure
the strap by its hook-and-loop closure. Ensure that the cable is clamped tightly
by the strap and that it cannot move.
3. If your cluster model requires two
fabric straps for cable management, route
the cable over the second strap an
d follow the procedure in step 2.
4. Verify that the cable is square and level with the port, with no strain on
the connector. This step is important to prevent possible electromagnetic
interference, which can leak past the EMI seals if the port and connector are
not correctly aligned and secured.
5. Route the cable bundles down the side of the rack by attaching the snap-on
straps as required. Use the mounting holes identified by callout 4 in Figure 1-1
and Figure 2-3. The vertical routing of the cable bundles depends on the
specific configuration.
2.3 Removing the Server for Servicing
Bring the component to an appropriate state for removal, and put the rack cabinet
into a safe and stable state for component removal. You must ensure that you can
reach the component easily and handle it safely. Remove the server as follows:
1. Switch off the power supp
ly from the rack’s power distribution unit and
disconnect the server’s
power cable.
2. Disconnect and remove each network cable until all networking ports are
unplugged.
3. Unstrap the cable and remove its connector from the PCI card port. When
disconnecting the cable, ensure that you do not bend it more than the
recommended bend radius. The cable specifications are provided in the
documentation for your cluster type.
4. Unlock and slide the s
erver all the way out of the rack, as described in the
documentation for t
he server rack kit.
