Removing and Installing a Power Supply
Problem
The JA1500 appliance ships with one AC power supply that is cold-swappable. You must remove a failed power supply and insert a new one while the main power is off.
The JA1500 appliance is upgradable to a redundant hot-swappable dual power supply. If the JA1500 appliance includes two power supplies, plug each power cord into a separate power circuit to ensure that the device continues to receive power if one of the power circuits fails. If a power supply fails, you can remove it while the other functioning power supply carries the full power load.
When a power supply fails, the red Failure status LED lights on the front panel of the JA1500 appliance. See Figure 13.

Solution
Before you begin removing a power supply from a JA1500 appliance, ensure that you have taken the necessary precautions to prevent ESD damage.
To remove a failed power supply and install a new one:
- Place the antistatic bag or the antistatic mat on a flat, stable surface.
- Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
- Remove the power source cable from the power supply faceplate. Pull out the female end of the power cord connected to the power supply faceplate.
- Push on the locking ejector lever to the right
until it is in its furthest position. See Figure 14.

- Grasp the power supply handle and pull firmly to slide it halfway out of the appliance.
- Place one hand under the power supply to support it and slide it completely out of the appliance.
- Place the power supply in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
- Remove the new power supply from the antistatic bag.
- Insert the new power supply until the ejector lever
locks. See Figure 15.

The red failure alarm on the JA1500 front panel goes out when the new power supply is powered on and the alarm silences.
