2.1.1 LEDs
Figure 2-1 reveals several LEDs that provide useful information about the state of the xStack
Storage Array. The Power LED illuminates when the system is powered. The bicolor Boot and
Fault LED will remain clear during bootup and then green if booting is successful. If the boot
process is unsuccessful, or a system fault occurs, then it will turn red.
Each of the fifteen drive bays has two LEDs associated with it, a bicolor drive activity and
fault LED and a drive power LED. Table 2-1 describes the front panel LEDs and their functions.

2.1.2 Key Lock and Latches
Figure 2-1 shows the xStack Storage Array’s front bezel with key lock and one latch. This
bezel can be locked in place to protect the system from unauthorized drive access and
removal.
Bezel Removal: Simply press inwards (as the arrow reveal) on the left latch shown in Figure
2-1 and pull the left side outwards. The bezel will come off easily providing access to the
drive bays behind it. If the key lock is in the locked position, then the latch cannot be pressed
inwards.
Bezel Installation: Align the bezel in front of the chassis with the bezel slightly to the left.
Carefully insert the catch found on the right side of the bezel under the receptacle found on
the right-front of the chassis and push the left side of the bezel to the right and forward until
the latch locks. The latch is spring-loaded and will lock into place. If you wish, you can use
the key lock to prevent drive access by turning it to the locked position.
