SSR1200 Power Supply Maintenance

SUMMARY Maintaining an SSR1200 appliance includes replacing power supplies. Replacing includes removing a failed power supply and installing a functional power supply.

Replacing an AC Power Supply on the SSR1200

The two AC power supplies (part number: SSR1200-AC-PS) are hot-removable and hot-insertable field-replaceable units (FRUs) installed in the rear panel of the SSR1200 appliance. You can remove and replace them without powering off the SSR1200 or disrupting SSR1200 functions.

Ensure that you have the following parts and tools available:

  • ESD grounding strap

  • Antistatic bag or an antistatic mat

  • Replacement AC power supply

Removing the AC Power Supply from an SSR1200

To remove a power supply from the appliance:

  1. If the AC power source outlet has a power switch, set it to the off (0) position and pull out the power cord connected to the power source outlet.
  2. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to the ESD point on the chassis.
  4. Pull the power cord retainer up and remove the power cord from the power supply faceplate.
  5. Slide the ejector lever towards the right (see Figure 1) until the power supply is unseated.
  6. Grasp the power supply handle and pull firmly to slide the power supply halfway out of the chassis.
  7. Place one hand under the power supply to support it and slide it completely out of the chassis. Take care not to touch power supply components, pins, leads, or solder connections.

  8. Place the power supply in the antistatic bag or on the antistatic mat placed on a flat, stable surface.

Installing the AC Power Supply in an SSR1200

To install an AC power supply:

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. If the power supply slot has a cover panel on it, remove the cover panel. Save the cover panel for later use.
  3. Taking care not to touch power supply pins, leads, or solder connections, remove the power supply from the bag.
  4. Using both hands, place the power supply in the power supply slot on the rear panel of the SSR1200 and slide it in until it is fully seated and the ejector lever fits into place. You will hear a distinct click when the power supply is fully seated in the chassis.
