Powering on the system

After you install all hardware components, you must power on the system and check its status.

About this task

Note: Each power supply unit includes a cable retainer to secure the power cable.

Use the cable retainers to secure the power cables from being accidentally pulled out of the node. The cable retainer, which is on the back of each PSU, 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 the following figure. 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 node.

Figure 1. Routing the power cables through the cable retainers

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.

Power on the node. Use the supplied power cords to connect both power supply units of the node 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.
Notes:
- Each node has two power supply units. To provide power failure redundancy, connect the two power cords to separate power circuits.
- Ensure that each power cable is secured to each PSU on the back of the node.
From the rear of the node, check the LEDs on the node canister.

- 1 Power
- 2 Status
- 3 Fault
The canister is ready for initialization with no critical errors when Power is illuminated, Status is flashing, and Fault is off.

What to do next

Next, you will connect an Ethernet cable to the technician port on the node, and initialize the system.
