You can install up to 16 InfiniBand cables in the HP BLc 4X DDR InfiniBand Gen 2 Switch. It is

not necessary to install the InfiniBand cables in any particular order. However, for the sake of

consistency, begin installing the InfiniBand cables in port 1 and continue installing the cables up

to port 16.

2.2.1 Removing an InfiniBand Cable from the HP BLc 4X DDR InfiniBand Gen 2

Switch

To remove an InfiniBand cable from the HP BLc 4X DDR InfiniBand Gen 2 Switch, pull the QSFP

connector release tab (see callout 2 in Figure 2-3) which releases the connector while using your

other hand to remove the connector from the switch port.

To completely remove the cable, it might be necessary to remove a releasable cable tie on the HP

c-Class blade cable management bracket.

If it is necessary to remove a releasable cable tie from the cable management bracket to fully

release a QSFP InfiniBand connector from the switch, reverse the installation procedure

documented in the HP Cluster Platform c-Class Blade Cable Management Bracket Installation Guide

(see Section 2.3).

2.3 InfiniBand Cable Management Bracket

Once the InfiniBand cables are installed in the HP BLc 4X DDR InfiniBand Gen 2 Switch they

will require additional support and strain relief. To provide support and strain relief for the

InfiniBand cables, you must install a cable management bracket. For more information on the

cable management bracket for the HP BLc 4X DDR InfiniBand Gen 2 Switch, see the HP Cluster

Platform c–Class Blade Cable Management Bracket Installation Guide on the High Performance
