4.4.3 Installing the Cabling Clamps
If line boards are installed in slots 1 and 2 of the chassis (the topmost slots) or the number of
cables connected to the interconnect exceeds 128 and the interconnect is installed in a standard
600mm wide cabinet, additional cabling clamps are required, as shown in
Figure 4-13 , which
shows the cable clamp installation on the rack's rear right column.

Note:
The following procedure is optional and only necessary in older configurations when the two
upper rows of the interconnect are used and when the cables connected to the interconnect exceed
128 and the interconnect is installed in a standard 600mm cabinet. A newer 800mm wide cabinet
is now used in large InfiniBand configurations eliminating the need to use this procedure.
Use the following procedure to install the four clamps:
1. Identify locations U21 and U23, identified by callout 1 in Figure 4-13 on the inner side of
both rear rack columns. Mark these locations with a pen or masking tape.
2. Clip an M6 cage nut in the back of each location, indicated by callout 2 in Figure 4-13 . Use
a total of eight nuts, two per clamp.
3. Insert an M6 x 10mm machine screw, indicated by callout 2 in Figure 4-13 , through each of
the cable clamp's square mounting washers. Use two washers per clamp.
4. Secure the cable clamp to the rack columns by using a #2 cross-point (Phillips or Posidrive)
screwdriver.
