Loading the Single Connector Assembly (SCA) Drives Into the System

The SGI 2400 and 2800 use an SCA sled assembly for mounting into the drive bay. Disk

drive modules are aligned vertically at the front of the chassis, as shown in Figure 5-2.

Note that the leftmost disk drive—the system drive—is oriented differently from the

others.

The drive bays in the modules use single-ended, ultra SCSI drives only. The server’s SCSI

drive box enclosure can support other types of drives, depending on how the box is

conﬁgured.

To insert a disk module, follow these steps:

1. If necessary, snap the handle to the open position so that it is centered, as shown in

Figure 5-2.

2. If you are adding a drive, remove the drive ﬁller plate that covers the drive slot you

want to use.

3. Align the new disk module with the drive guide, as shown in Figure 5-2.

4. Gently but ﬁrmly slide the disk module on the guides over the pin.

5. When the disk module is all the way in, snap the handle right to the closed position,

as shown in Figure 5-2. In the case of the system disk module, which is upside

down relative to the other drives, snap the handle left.
