Installing a DC Power Supply in an EX 8200 series Switch

The DC power supply in an EX 8200 series switch is a hot-insertable and hot-removable field-replaceable unit (FRU). Up to six DC power supplies can be installed in an EX 8200 series switch. All DC power supplies install in the front of the chassis in the slots provided at the bottom. See Slot Numbering for an EX 8216 Switch.

Note: DC power supplies are not supported on EX 8208 switches currently.

Before you install a DC power supply in the switch:

Ensure that you have the following parts and tools available to install a DC power supply in an EX 8200 series switch chassis:

  • Electrostatic discharge (ESD) grounding strap
  • Phillips (+) screwdriver, number 1

To install a DC power supply in an EX 8200 series switch (see Figure 1):

  1. Attach the electrostatic discharge (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, unscrew the screw on the side of the cover panel in the counterclockwise direction using the Phillips (+) screwdriver, number 1, and remove the cover panel. Save the cover panel for later use.
  3. Taking care not to touch power supply components, pins, leads, or solder connections, remove the power supply from its bag.
  4. Flip the Enable switch on the power supply to the Standby position.
  5. Unscrew the captive screw in the counterclockwise direction using the Phillips (+) screwdriver, number 1.
  6. Pull the captive screw away from the faceplate of the power supply to release the latch.
  7. Pull the handle away from the faceplate of the power supply until it is perpendicular to the faceplate.

    Note: Power supplies can be installed in any slot. You do not have to install the power supplies in serial order.

  8. Using both hands, place the power supply in the power supply slot on the front of the switch. Slide the power supply straight into the chassis until the power supply is fully seated in the slot. Ensure the power supply faceplate is flush with any adjacent power supply faceplates or power supply cover panels.
  9. Push the handle towards the faceplate of the power supply until it is flush against the faceplate.
  10. Push the captive screw into the power supply faceplate. Ensure that the screw is seated inside the corresponding hole on the faceplate.
  11. Tighten the captive screw by turning it clockwise using the Phillips (+) screwdriver, number 1. When the screw is completely tight, the latch locks into the switch chassis.
