2 Maintaining Disk Drives
Each PS6500 array includes 48 hot-swappable disk drives. See the PS Series Release Notes for the latest
information about disk drive support.
You access disk drives from the front of the array after removing the bezel and opening the chassis cover. See
Removing and Installing the Bezel on page 1-8 and Opening and Closing the Chassis Cover on page 1-9.
Disk Drive LEDs
There are several LEDs on a PS6500 array that indicate the status of disk drives:
• On the bottom front of the array, in the center, the disk hardware status LED (circled in Figure 2-1) shows the
overall status of the disk drives. This LED panel is visible with the bezel on.

• When you remove the bezel, a row of 48 LEDs (12 sets of four) is visible at the bottom of the front panel.
These LEDs are on both sides of the hardware status LED panel.

Each LED corresponds to a specific disk drive and shows its activity. From left to right, the first set of LEDs
corresponds to disk drives 0 to 3 (the first column of disk drives), the second set corresponds to disk drives 4 to
7 (the second column of disk drives), and so on.
• Each drive has an LED on the top of the drive, opposite the latch.
