Installing and removing the SAN32C-6 switch cooling duct assembly

Use this procedure if you need to install or remove the switch cooling duct of the FlashSystem 9500R racked system. This ducting system is supplied free of charge on the initial order of the 8977-T32 only as part of an FlashSystem 9500R, there is no mechanism to order it independently outside of an FlashSystem 9500R.

Before you begin

The Fibre Channel switches in the FlashSystem 9500R racked system provide a dual-redundant Fibre Channel fabric to the control enclosures in the rack. If the system is to remain online, power down or service one switch at a time. Ensure that the other switch remains connected to control enclosures and power supplies.

FlashSystem 9500R racked system contains two rear mounted switches. Each switch is installed in position 38 of the rack, and the second is installed in position 40.

1. At the rear of the rack, route a power cable from the upper outlet of the left PDU, up the rack, through the upper left cableway of the rack, to the front of the rack where the switches will be installed. If a second power supply is installed in the switch, also, route a second power cable from the upper outlet of the right PDU, through the upper right cableway of the rack, to the front of the rack where the switches will be installed. Figure 2 shows suitable routes. Do not plug the connectors into the outlets yet.

   Tip: If you are installing a pair of switches, also install one or two power cables for the second switch.

2. Install caged nuts [7] behind the upper and lower screw holes of the 1U rack position where the switch is to be mounted.
3. Install two rear brackets [3] onto the outside of the rack, pointing inwards, and secure each with two M5 screws [8] into the caged nuts [7] at the rear of the rack.
4. Attach one air duct rail assembly onto each side of the switch using the 16 provided M4 screws [6].
5. Insert the switch and rail assembly into the front of the rack, locating the rear end of the rail into the rear brackets [3].
6. Secure the front of the rails to the rack with a pair of M5 screws [8].
7. At the front of the rack, locate the sliding cable door inside the front of the right rail and install the right power cable:
   1. Loosen the thumbnut then slide the door open by pulling the end of the door outward from the rack.
   2. Feed the power cable through the cable doorway and connect to the right power supply of the switch.
   3. Press the door closed so that the cable is snug in the doorway, then tighten the thumbnut - do not overtighten.
8. If a second PSU is installed in the switch, install the left power cable through the left rail and connect to the left power supply inlet of the switch.

   Tip: If you are installing a pair of switches, repeat the above steps to also assemble and install the second switch.

9. Slide the bottom cover [5] onto the lower ledge of the air duct rail [2]. When fitted correctly, the raised edge tabs of the bottom cover are above the ledge and the flat tabs are below the ledge.
10. Slide the top cover bezel assembly [4] onto the upper ledge of the air duct rail [2]. When fitted correctly, the flat edge tabs of the top cover are above the ledge and the middle tabs are below the ledge.
11. Secure the top cover using the two thumbnuts on the front of the top cover [4] - turn them clockwise to screw them into the front of the rail. Do not overtighten them.
