Maintaining the JRR200 Power System

Maintaining the JRR200 Route Reflector Power Supplies

Purpose

For optimum performance, verify the condition of the power supplies.

Action

On a regular basis:

  • To check the status of the power supplies, issue the show chassis environment pem command. The output shown below is an example.

  • Make sure that the power and grounding cables are arranged so that they do not obstruct access to other JRR200 route reflector components.

  • Routinely check the status LEDs on the power supply faceplates to determine whether the power supplies are functioning normally. Each power supply faceplate displays three LEDs to indicate the status of the power supply.

  • Check the power LED on the front panel of the device. Power supply failure or removal triggers an alarm that causes LEDs to light. You can display the associated error messages by issuing the following command:

  • Periodically inspect the site to ensure that the grounding and power cables connected to the device are securely in place and that there is no moisture accumulating near the device.

Replacing the JRR200 Route Reflector AC Power Supply

Each AC power supply is a field-replaceable unit (FRU) installed in the rear panel of JRR200 route reflector. You can remove and replace the power supplies without powering off JRR200 route reflector or disrupting route reflector functions.

Note:

All the power supplies must be installed and operational for optimal functioning of JRR200 route reflector.

Removing a JRR200 Route Reflector AC Power Supply

Ensure that you have the following parts and tools available:

  • ESD grounding strap

  • Antistatic bag or an antistatic mat

  • Replacement power supply

To remove a power supply from JRR200 route reflector (see Figure 1):

  1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to the ESD point on the chassis.
  3. 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.
  4. Remove the power cord from the power supply faceplate.
  5. Slide the ejector lever toward the left 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 a JRR200 Route Reflector AC Power Supply

Ensure that you have the following parts and tools available:

  • ESD grounding strap

CAUTION:

Do not mix AC and DC power supplies in the same chassis.

To install an AC power supply (see Figure 2):

  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, with one hand slide the ejector lever toward the left until it stops and using the other hand pull the handle of the cover panel outward to remove it. 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 JRR200 route reflector 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.

Replacing the JRR200 Route Reflector DC Power Supply

Each DC power supply is a field-replaceable unit (FRU) installed in the rear panel of the JRR200 device. You can remove and replace the power supplies without powering off the JRR200 device or disrupting route reflector functions.

Note:

All the power supplies must be installed and operational for optimal functioning of the JRR200 device.

Removing a JRR200 Route Reflector DC Power Supply

Ensure that you have the following parts and tools available:

  • ESD grounding strap

  • Phillips (+) screwdriver, number 2

  • Antistatic bag or an antistatic mat

  • Replacement power supply

To remove a DC power supply (see Figure 3):

  1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  3. Make sure that the voltage across the DC power source cables leads is 0 V and that there is no chance that the cables might become active during the removal process.
  4. Remove the plastic cover from the input terminals by sliding the cover either to the left or right.
  5. Unscrew the locking screws counterclockwise by using the screwdriver.
  6. Remove the cable lugs from the input DC terminals.
  7. Slide the ejector lever toward the left until the power supply is unseated.
  8. Grasp the power supply handle and pull firmly to slide the power supply halfway out of the chassis.
  9. Taking care not to touch power supply pins, leads, or solder connections, place one hand under the power supply to support it. Grasp the power supply handle with your other hand and pull the power supply completely out of the chassis.

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

Installing a JRR200 Route Reflector DC Power Supply

Ensure that you have the following parts and tools available:

  • ESD grounding strap

CAUTION:

Do not mix AC and DC power supplies in the same chassis.

To install a DC power supply (see Figure 4):

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Taking care not to touch power supply pins, leads, or solder connections, remove the power supply from the bag.
  3. Using both hands, place the power supply in the power supply slot on the rear panel of the chassis 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.
