Note: When you connect cables to the SAS ports on the left side of the node canister, each host must
be connected to both canisters. Both canisters must have the same number of cables connected.
2. Arrange the cables to provide access to the hardware.
• USB ports. USB port access is required when you use a USB flash drive to configure the system.
• Access is required to the hardware for servicing and for safely removing and replacing components
by using two or more people.
Powering on the system
After you install 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. Open bays or slots disrupt the
internal air flow, causing the drives to receive insufficient cooling.
• Every unused drive bay must be occupied by a filler panel.
• Filler panels must be installed in all empty host interface adapter slots.
Note: The AC power supply unit, and the DC power supply unit in DC-powered models, features a cable
retainer to secure the power cable.
Use the cable retainers to secure the power cables from being accidentally pulled out of the enclosure.
The cable retainer, which is on the back of each PSU handle, has a curved opening that faces the rear of
the PSU. After you plug the power cables in to the PSU, slip the power cable behind the retainer. Then,
pull the cable back into the retainer opening to secure the cable.
Each cable must be routed through the retainer, as shown in Figure 75 on page 72. For PSU 1, hook the
power cable underneath the cable retainer so the cable can extend to the left. For PSU 2, make a loop to
secure the cable under the retainer and extend the power cable to the right side of the enclosure.
Figure 75. Routing the power cables through the cable retainer
To remove the power cable, push the cable forward to unhook it from the cable retainer. Then, unplug the
cable from the PSU.
Procedure
To power on the system, complete the following steps.
1. Power on all expansion enclosures. Use the supplied power cords to connect both power supply units
of the enclosure to their power sources.
If the power sources have circuit breakers or switches, ensure that they are turned on. The enclosure
does not have power switches. Repeat this step for each expansion enclosure in the system.
Note: Each enclosure has two power supply units. To provide power failure redundancy, connect the
two power cords to separate power circuits.
2. From the rear of the expansion enclosure, check the LEDs on each expansion canister (see Figure 76
on page 72).
