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 latches cannot be pressed inwards. Bezel Installation: Align the bezel in front of the chassis and push forward. The latches are 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. 16 Chapter 2 Identifying Hardware Components

Key Lock and Latches
Figure 2-1 shows the xStack Storage Array’s front bezel with key lock and two latches.
This
bezel can be locked in place to protect the system from unauthorized drive access and
removal.
Bezel Removal: Simply press inwards (as the arrows reveal) on the two latches shown in Figure
2-1.
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 latches cannot be pressed inwards.

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.
