Removing a PCI adapter from a double-wide, generation 2.5 cassette

You can remove a PCI-X double-wide, quad-channel Ultra320 SCSI RAID Controller or PCI-X DDR 1.5 GB cache SAS RAID Adapter from a generation 2.5, double-wide cassette.

This procedure is for use by service providers.

Attention: Do not touch exposed electronic components on the adapter during this procedure or short them with any type of metal object.

Before you begin: Ensure that you have the following tools and parts:

• Phillips screwdriver
• Needle-nose pliers
• Complete cassette-assembly, FRU 44V5205^*
  • The cassette assembly contains extra screws or clips. Some of these parts are left over after the assembly.
• One of the following double-wide adapters:
  • PCI-X double-wide, quad-channel Ultra320 SCSI RAID Controller, FRU 42R6578^*, or later.
  • PCI-X DDR 1.5 GB cache SAS RAID Adapter, FRU 44V5193^*, or later.

The cassette assembly can also be ordered with the double-wide adapter already installed using one of the following FRUs:

• PCI-X double-wide, quad-channel Ultra320 SCSI RAID Controller, FRU 44V4608^*, or later.
• PCI-X DDR 1.5 GB cache SAS RAID Adapter, FRU 44V7627^*, or later.

^*Designed to comply with RoHS requirement

Tip: If you are reassembling an adapter into the cassette, pay close attention to how the pieces come apart.

The following figure shows the PCI-X double-wide, quad-channel Ultra320 SCSI RAID Controller and the main parts that make up the cassette assembly. The PCI-X DDR 1.5 GB cache SAS RAID Adapter looks similar and the same illustrations are used for both adapters. Some steps refer to the adapter tail stock, which is the front end of the adapter with the external connectors. The other end of the adapter is referred to in the steps as the rear of the adapter.

To remove the double-wide adapter from the cassette assembly, do the following steps:

1. Remove the cassette assembly from the I/O expansion unit:
   1. Ensure that the locking arms (A) are down as shown in Figure 2.
   2. Lift on the top of the tail stock brackets to undock the back part of the adapter from the PCI connector on the chassis and detach the tail stock from the openings in the chassis.
   3. Carefully slide the cassette assembly all the way out of the I/O expansion unit. See Figure 2.
   Figure 2. Removing the cassette assembly from the I/O expansion unit

   
2. Raise the locking arms to the full up position and remove the two metal clips from the front of the assembly. See Figure 3
   Figure 3. Removing the two metal clips into the front of the assembly

   
3. Remove the push pin (A) from the top of cassette assembly by the tail stock. See Figure 4.
4. Remove the screw (B) from the bottom of the tail stock. See Figure 4.
5. Remove the screw (C) from the rear of the cassette assembly. See Figure 4.
   Figure 4. Removing the push pin and screws

   
6. Detach the outer arms of the face plate assembly by releasing the plastic locking tabs (A). See Figure 5.
   Figure 5. Detaching the face plate

   
7. Ensure that the locking arms are lowered at the start of this step. Then, detach the tab at the bottom of the cassette assembly from the notches on the face plate and lift on the locking arms. See Figure 6. Use care not to damage the plastic tab.
   Figure 6. Detaching the face plate

   
8. Remove the face plate from the front of the cassette assembly by sliding it down. Ensure that the top of the face plate detaches from the notches on both the front and sides of the cassette assembly. See Figure 7.
   Important:

   • Press in on the black tab (A) to release the metal, bottom, side tab of the face plate. This tab is the same location where you removed a screw in step 4
   • While sliding the face plate downwards, you might need to manipulate the top center rail of the face plate for it to continue to slide freely.

9. Remove the cover:
   1. Slide the cover away from the locking arms until the holes and corresponding tabs detach (B). See Figure 8.
   2. Pull the cover away from the adapter (A). See Figure 8.

10. Remove the small screw that secures the lower, rear arm of the cassette assembly from the rear end of the double-wide adapter. See Figure 9.
    Figure 9. Removing the lower, rear arm of the cassette assembly

    
11. With the levers on the cassette assembly fully extended out, detach all four corners of the cassette assembly from the double-wide adapter:
    1. Remove the top corner of the double-wide adapter tail stock from the notches in the cassette assembly. Then move the double-wide adapter tail stock up to free the bottom of the double-wide adapter tail stock from the cassette assembly. See Figure 10.
       Figure 10. Detaching the corners of the cassette assembly

       
    2. Detach the rear arms of the cassette assembly from the bottom corners of the double-wide adapter. See Figure 11.
       Figure 11. Detaching the rear arms of the cassette assembly

       
12. Pull the double-wide adapter away from the cassette assembly and carefully place it on an ESD protective surface. See Figure 12.
