Dell MD1280 manual Replacing chassis, Replacing rack rails

Replacing chassis

Replacing the chassis is required when non-FRU devices must be replaced. Replacing a chassis requires a scheduled maintenance window when the system is unavailable. The replacement chassis comes without any FRUs, and therefore all cards and DDICs must be transferred to the new chassis.

About this task

To replace a chassis, complete the following tasks:

Steps

1.Remove the Hold Down Brackets (HDBs).

a.Remove the fixing screws from the rear of the enclosure.

b.Remove the HDBs from the rear of the rack.

2.Remove all DDICs from the enclosure and place on a static free mat or bench. Note the slot position of each DDIC as you remove it, the DDICs must be reinstalled in the same slot position as in the original chassis.

3.Remove the enclosure from the rack rails.

WARNING: Do not attempt to lift the enclosure without any assistance. If installed above the lower 20U of a rack, a customer‐provided mechanical lift must be used to avoid injury.

4.Install the replacement chassis in the rack.

5.Install the HDBs.

6.Move all the back‐panel parts (EMMs, fans, and PSUs) from the original chassis to the racked replacement.

7.Move the front panel bezel from drive drawer 0 from the original chassis onto the racked replacement.

8.Install the DDICs into the replacement.

9.Turn on the enclosure as described in the Post-replacement tasks section in this document.

10.An update to the electronically stored product ID and Service Tag must be applied. Contact your service provider.

11.Swap the bezel on drive drawer 0 of the failed chassis with the bezel on drive drawer 0 of the new chassis before loading back into the rack.

12.Service Tag is not included in the replacement chassis. Remove the Service Tag label from the old chassis and adhere it to the replacement chassis. Alternatively, mark the replacement chassis with the Service Tag information or print a new tag.
