Panel LEDs
Note:
The QXS-2400 SSD ships as a RAID chassis (RBOD) only. The QXS-2400 SSD does not
support any additional drive expansions (JBODs).
The rear panel layouts of the 12-, 24-, 48-Drive Expansion Chassis are basically identical. All models
support 6-Gbit/s. Accordingly, the expansion chassis feature a “6 Gb/s” label above each SAS
(ingress/egress) expansion port.
Newer models of these drive expansion chassis feature AC power supplies without power switches, as per
the system shown below. See Power On/Power Off
for more information.
