5.3 Power On

Once all the components have been installed in the RAID subsystem, the iSCSI ports have

been connected to the network, power on the network devices, the subsystem, and then

power on the servers/iSCSI initiators.

5.3.1 Check List

Before powering on the RAID subsystem, please check the following:

• Memory Modules – Memory modules have been correctly installed on the controller

boards. You may skip this if you have not changed the pre-installed module.

• BBU Modules – If used, that the BBU modules 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 iSCSI ports on the subsystem have been correctly connected to

the initiator or the Ethernet network.

• Power Cords – The power cords have been connected to the PSU modules on the sub-

system and plugged into main power.

• Ambient Temperature – All the subsystem components have been acclimated to the sur-

rounding temperature.

5.3.2 Power On Procedure

When powering on the RAID subsystem, please follow these steps.

1. Power on the network connection devices.

These devices include the Ethernet switches, iSCSI routers, and any other such devices

that have been connected to the RAID subsystem. Please refer to the documentation that

came with your network device to see the power on procedure.

2. Power on the RAID subsystem.

The RAID subsystem should only be powered on after all the network connection devices

have been powered on first. Consult your network administrators for proper network

configurations. The power on procedure for the RAID subsystem is described below.

3. Power on the initiators.

The servers or iSCSI initiators should be the last devices that are turned on. Please refer

to the documentation that came with your initiator systems to see their own power on

procedures.

5.3.3 Power On Enclosure

To power on the subsystem, turn on the two power switches located on the rear panel of the

subsystem. (See Figure 5.33) Each switch controls a single PSU, therefore make sure that

both switches are turned on. There is no limitation on which PSU should be powered on first.
