Removing the front cover with the cover removal tool

Removing the front cover from the 9117-MMB, 9117-MMC, 9179-MHB, or 9179-MHC systems that were shipped before 1 March 2011 requires the use of a cover removal tool.

Systems that were shipped before 1 March 2011 require the use of a cover removal tool to prevent the front fans from being inadvertently removed and prevent an unexpected outage.
Note: The older covers that were shipped before 1 March 2011 can be identified by a single blue stripe (A) on the cover assembly latches. Newer covers that were shipped after 1 March 2011 have two blue stripes (B) on the cover assembly latches. See Figure 1.

Important: Do not remove the cover to view the enclosure serial number. If you need to check the enclosure serial number, use one of the following methods:
  • From the Advanced System Management Interface (ASMI), complete the following steps. This procedure can be performed in the FSP standby mode.
    1. Expand System Information.
    2. Click Vital Product Data in the left column.
    3. From the Vital Product Data panel, click Enclosure VPD (EV) for each enclosure configured.
    4. Click Details to view results.
  • From the Hardware Management Console (HMC), complete the following steps. The server must be powered on to the partition standby mode.
    1. Expand Hardware Information.
    2. Select View Hardware Topology to view the enclosure ID for each enclosure.

To remove the front cover with the cover removal tool, complete the following steps:

  1. Remove the cover removal tool (PN 74Y9219) from the shipping box, if needed.
  2. If necessary, open the front rack door.
  3. Align the cover removal tool (A) with the front cover of the system as shown in the following figure.
    Figure 2. Aligning the cover removal tool

    Note: The top pins of the cover removal tool align with the second hole down from the top of the cover. Pins must be inserted through the hole until the removal tool pins contact the system and cannot be pushed forward any further. There is a gap between the system and the cover removal tool.
  4. Place hands on the cover removal tool as shown in the following figure while pressing the tool against the system.

  5. While keeping forward pressure on the cover removal tool, pull the cover assembly latches to disengage them as shown in the following figure, which releases the retention mechanism.

  6. If the front cover is difficult to remove, the cover might be adhering to the fan assemblies at the top of the system. Apply forward pressure against the cover removal tool and place fingers underneath the edge of the cover near the top corners. Then, pull the cover toward the cover removal tool as shown in the following figure.

  7. After the cover assembly is unlatched and lying against the cover removal tool, remove both from the front of the system as shown in the following figure.

  8. Repeat these steps for all system covers that must be removed.
