Once all the components have been installed in the EonStor subsystem and the host
channels have been connected to the host and the expansion cables have been connected
to the JBODs, the subsystem can be powered on.
4.3.1 Check List
BEFORE
powering on the ES U16U subsystem, please check the following:
Memory Modules –
If new memory modules were installed, make sure that they
have been correctly installed on the controller boards.
BBU Modules
–If installed, make sure the BBU Modules and the battery
charger board have been installed correctly.
Hard Drives –
Hard Drives have been correctly installed on the drive trays.
Drive Trays

ALL
the drive trays, whether or not they have a hard drive, have
been installed into the subsystem.
Cable Connections –
The host ports on the subsystem have been correctly
connected to a host computer.
Power Cables –
The power cables have been connected to the PSU modules on
the subsystem and plugged into the mains.
Ambient Temperature
– All the subsystem components have been acclimated to
the surrounding temperature.
4.3.2 Power On S equence
When powering on the ES U16U subsystem, please follow these steps.
1.
Power on external storage devices
If a six channel ES U16U subsystem has been connected to an external SCSI-320
storage device as shown in
Figure 4-3
, the external storage device should be
powered on first.
2.
Power on the EonStor subsystem
The ES U16U should be powered on before the host computers. The power on
procedure for the ES U16U subsystem is described below.
