3.6.5 Management switch: BMC + GW SoC cabling
Start cabling using a 1.0m blue RJ45 cable and insert one end into port 32 of the management switch.
Run the cable through the loop in the OSFP connector as shown in the left hand picture in
Fig. 3.49 and connect
it to the BMC+GW port on IPU-M2000 #16.

Repeat the process for ports 31 to 25 using 1.0m blue cables, and ports 24 to 17 using 1.5m blue cables. When
all cables have been connected, dress the loom down the side of the cabinet and secure the bundle with a Velcro
strip, as shown in the right hand picture in Fig. 3.49 . Using a 1.0m blue cable, connect port 7 of the management
switch to the top RJ45 connector on the ToR Switch ( Fig. 3.50 ).

With the IPU-M2000s numbered from bottom to top, the BMC + GW SoC ports should be connected to the
management switch as given in Table 3.6 .
