After installing all hardware components, you must power on the system and
check its status.
About this task
Attention: Do not power on the system with any open bays or slots.
v Every unused drive bay must be occupied by a filler panel.
v Filler plates must be installed in all empty canister bays and host interface card
slots.
Open bays or slots disrupt the internal air flow, causing the drives to receive
insufficient cooling.
Procedure
To power on the system, complete the following steps.
1. Power on all expansion enclosures by plugging the power cords into properly
grounded electrical outlets. There is no power switch.
Note: Each enclosure has two power supply units. To provide power failure
redundancy, connect the two power cords to separate power circuits.
2. Check the LEDs on each expansion canister (see Figure 36).
