HP StorageWorks Disk System 2120 8
Components of the Disk System
Front Panel
The disk modules can be accessed from the front of the disk system. It can accept up
to 4 low profile disk drives. If your storage system contains less than 4 disk modules,
the remaining empty slots contain filler panels. These filler panels (part number
A6198-60002) ensure that the proper cooling is maintained within the storage system.
Remove filler panels only when a disk module is added to the system.
Disk Module LEDs
Each disk module has two LEDs: an amber LED on the top (see Figure 1) and a green
LED on the bottom. The amber LED is not operational. The green LED provides disk
module status information as listed in Table 6.
