4.1 Expansion Array Front Panel Components The front of the DSN-5000-10 expansion array enclosure has the following components (see Figure 4-1):  LEDs - four enclosure LEDs at the right side of the front panel provide status information about the DSN-5000 series primary array enclosure. For a description of these LEDs, see Table 4-1.  Drive slots - the front panel provides access to 12 drive slots. The drive slots are arranged in four columns of 3 slots.  Drive carriers - drives are mounted on a drive carrier. Drive carriers have a push-button lever for installing and removing drives, and three status LEDs (see Figure 4-2 and Table 4-2). Each carrier has a corresponding drive slot number (see Figure 4-3). Filler panels must be installed in all drive slots that are not occupied by a drive.

Enclosure LEDs Color Green Amber Green Blue Description ON = DSN-5000-10 expansion array is powered on. OFF = power is not being received. ON = a fault occurred with the power supply, fan, over temperature, internal module, or controllers. OFF = normal operation. ON = normal operation. OFF = normal while DSN-5000-10 expansion array is booting. After initialization, this status indicates a problem with the DSN-5000-10 expansion array. Blink = DSN-5000-10 expansion array is trying to identify the physical location of a drive using the xStack Storage Management Center. OFF = no intent of identification is being performed. 26 Chapter 4 DSN-5000 Expansion Array Layout and Installation
