Chapter 4: Subsystem Connection and Operation
BBU: If used, make sure the optional BBU has been installed correctly in the
Hard drives: Hard drives have been correctly installed in the drive trays.
Drive trays: All the drive trays, whether or not they contain a hard drive, have been installed into the subsystem.
DIP switch settings: All the appropriate DIP switch settings have been made. The hub has been enabled/disabled (as required) and the channel speed has been properly configured.
Cable connections: The subsystem has been correctly connected to host computer(s), external networking devices, expansion enclosures, and/or cascaded subsystems.
Power cords: The power cords have been connected to the PSUs on the subsystem and plugged into the main power source.
Ambient temperature: All the subsystem components have been acclimated to the surrounding temperature.
4.5.2Power On Procedure
When powering on the subsystem, please follow these steps:
Step 1. Power on the Fibre Channel connection devices.
These devices include the FC switches and any other such device that have been connected to the subsystems. Please refer to the documentation that came with your networking devices to see their power on procedure.
Step 2. Power on the cascaded subsystems or the expansion JBODs that are not connected directly to the host computers.
Step 3. Power on the subsystem.
The subsystems should be powered on before the host computers. Turn the power switch on. (See Figure
(1)power switch that controls all PSUs is shielded by an anti- tamper plastic cover.
