Replacing the AC Power Supply Cord on a Junos Space Appliance

Note:

If only one power supply module is installed in your Junos Space Appliance, you must power off the appliance before replacing the power supply cord.

This topic contains the following sections:

Disconnecting the AC Power Supply Cord

To disconnect an AC power supply cord from a Junos Space Appliance, do the following:

  1. (Optional) Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an external ESD point.
  2. If the AC power source outlet has a power switch, set it to the OFF position. If the AC power source outlet does not have a power switch, gently pull out the plug end of the power cord connected to the power source outlet.
  3. If the power cord has the retainer clip and adjustment nut installed, turn the adjustment nut so that the power cord can be removed from the slot in the adjustment nut.
  4. Unplug the power cord from the power supply module.

Connecting the AC Power Supply Cord

To connect an AC power supply cord to a Junos Space Appliance, do the following:

  1. (Optional) Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an external ESD point.
  2. If the power cord retainer clip is not installed on the power supply module, squeeze the two sides of the power cord retainer clip and insert the L-shaped ends of the wire clip into the holes in the bracket on each side of the AC power cord inlet on the power supply module, as shown in Figure 1.

  3. Locate a replacement power cord with the type of plug appropriate for your geographical location.
  4. If the AC power source outlet has a power switch, set it to the OFF position.
  5. Insert the power cord plug into an external AC power source outlet.
  6. If the AC power source outlet has a power switch, set it to the ON position.
  7. Push the power cord into the slot in the adjustment nut of the power cord retainer clip. Turn the nut until it is tight against the base of the coupler and the slot in the nut is turned 90° from the top of the appliance, as shown in Figure 1.
  8. Connect the power cord to the power supply module.
  9. Verify that the power cord does not block the air exhaust and access to device components, or drape where people could trip on it.

The Junos Space Appliance starts powering on when you supply power to the power supply module. If the power supply cord is correctly installed, the LED on the power supply module displays green when the power supply module is powering the appliance, and amber when the power supply module is in standby mode (not powering the appliance).
