HP 16/18-Port Cable Management Kit Installation Guide Abstract This document describes how to attach the HP 16–Port or 18–Port Cable Management Kit to an HP rack. The cable management bracket is designed to align and support the cables that lead from an HP BladeSystem c-Class enclosure's 16–port or 18–port InfiniBand switch mounted in the rear of the chassis to another c-Class InfiniBand switch or an InfiniBand interconnect installed in an adjacent rack.

• ◦ Marker pen or masking tape ◦ Diagonal cutting pliers Resources: Cables of the type used by the HP BladeSystem c-Class InfiniBand switch. 1.6 Prerequisites Before you begin to mount the bracket: • Follow the usual cable-handling precautions for InfiniBand cables, see the InfiniBand switch manual that came with your switch. • Ensure you know how to plug in the InfiniBand cables, as described in the InfiniBand switch manual that came with your switch.
2 Aligning the Bracket Figure 2 shows the correct orientation of the cable management bracket which you must install before connecting the cables to the InfiniBand switch module. During the cabling procedure, the bracket provides strain relief for the InfiniBand ports, and maintains the correct minimum cable bend radius. Figure 2 Bracket Orientation 1 2 The following list describes the callouts shown in Figure 2: 1. Mounting hook installed in one of the mounting holes in the rack's rear left column 2.
1. 2. 3. 4. The U location that aligns with the top of the HP BladeSystem c7000 enclosure. Each c7000 enclosure is 10U high.
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 Table 2. 3.

Figure 5 InfiniBand Cable Secured with a Releasable Cable Tie 1 2 Caution: The releasable cable tie should only be hand tight. Do not use a cable tie installation tool and do not over tighten the releasable cable tie or it might damage the InfiniBand cable. 4. Leaving approximately 1/4 inch to 3/8 inch coming out of the buckle, clip the excess from the releasable cable tie.
4 Removing InfiniBand Cables and Switches This chapter describes the procedure to remove a damaged InfiniBand cable or InfiniBand switch for repair. 4.1 Removing a Damaged Cable From the c-Class Cable Management Bracket To remove a damaged cable, follow these steps: 1. Bring the HP BladeSystem c-Class enclosure to an appropriate state for service as described in the HP BladeSystem c7000 Enclosure Maintenance and Service Guide on the HP website: http://h20000.www2.hp.
4. Leave the cables secured in the cable management bracket and carefully set the bracket aside. Caution: Do not bend the InfiniBand cables more than the minimum bend radius recommended by the cable manufacturer. 5. 6. Push the blade handle release button to release the blade handle. Open the blade handle and slide the switch all the way out of the HP BladeSystem c7000 enclosure. 4.
