SRX1600 Power Supply Maintenance

date_range 30-Jan-24

arrow_forward

Maintaining an SRX1600 includes removing a failed power supply unit (PSU) and installing a functional PSU.

Replace an AC PSU on the SRX1600

The SRX1600 rear panel has two AC PSUs which are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace the PSUs without powering off the SRX1600 or disrupting the firewall functions.

Ensure that you have the following parts and tools:

  • An electrostatic discharge (ESD) grounding strap

  • An antistatic bag or an antistatic mat

  • A replacement AC PSU

  • A blank cover panel (in case you're not replacing the component)

Remove the AC PSU from the SRX1600

To remove an AC PSU from the appliance (see Figure 1):

CAUTION:

Avoid leaving the PSU slot empty for more than 30 minutes when the device is operational. For proper airflow, you must place the PSU in the chassis. Always cover the empty PSU slot with a blank panel.

  1. If the AC power source outlet has a power switch, set it to the off (O) position.
  2. Pull out the power cord connected to the power source outlet.
  3. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  4. Attach an ESD grounding strap to your bare wrist and connect the strap to the ESD point on the chassis.
  5. Unplug the power cord from the device inlet on the PSU.
  6. Press the latch, which is on the right side of the power outlet, to the left.
  7. Pull the PSU straight out of the chassis.

  8. Place the PSU in the antistatic bag or on the antistatic mat that you've placed on a flat, stable surface.
  9. If you're not replacing the power supply, install the cover panel over the PSU slot.

Install the AC PSU in the SRX1600

To install an AC PSU (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 PSU slot has a cover panel on it, remove the cover panel. Save the cover panel for subsequent use.
  3. Taking care not to touch power supply pins, leads, or solder connections on the PSU, remove the PSU from the bag.
  4. Using both hands, place the PSU in the PSU slot on the rear panel of the SRX1600. Slide the PSU straight into the chassis until the PSU is fully seated in the chassis slot. Ensure that the PSU faceplate is flush with the adjacent PSU faceplate.

  5. Connect the power cord (see Connect the SRX1600 to Power).

Replace a DC PSU on the SRX1600

The rear panel of the SRX1600 has two DC PSUs, which are hot-removable and hot-insertable field-replaceable units (FRUs).You can remove and replace the PSUs without powering off the SRX1600 or disrupting the firewall functions.

Ensure that you the following parts and tools are available:

  • An ESD grounding strap

  • An antistatic bag or an antistatic mat

  • A replacement DC PSU

  • A blank cover panel (in case you're not replacing the component)

Remove the DC PSU from an SRX1600

To remove a DC PSU from the appliance (see Figure 3):

CAUTION:

Avoid leaving the PSU slot empty for more than 30 minutes when the device is operational. For proper airflow, you must place the PSU in the chassis. Always cover the empty PSU slot with a blank panel.

  1. Attach an ESD grounding strap to your bare wrist and connect the strap to the ESD point on the chassis.
  2. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  3. Switch off the external circuit breakers for all the cables connected to the PSU. Make sure that the voltage across the power source cable leads is 0 V. You must remove any possibility for the cables to become active during the removal process.
  4. Remove the clear plastic cover protecting the terminal studs from the faceplate.
  5. Remove the screws and washers from the terminals using a number 2 Phillips screwdriver.
  6. Remove the cable terminals from the terminal studs. Carefully move the power cables out of the way.
  7. Press the latch, which is on the right side of the power outlet, to the left.
  8. Pull the PSU straight out of the chassis.

  9. Place the PSU in the antistatic bag or on the antistatic mat that you've placed on a flat, stable surface.
  10. If you're not replacing the power supply, install the cover panel over the slot.

Install the DC PSU in the SRX1600

To install a DC PSU (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. Switch off the circuit breaker on the panel board that services the DC circuit. Tape the handle of the circuit breaker in the OFF position. Make sure that the voltage across the power source cable leads is 0 V. You must remove any possibility for the cables to become active during the removal process.
  3. If the PSU slot has a cover panel on it, remove the cover panel. Save the cover panel for subsequent use.
  4. Taking care not to touch the power supply terminals, leads, or solder connections on the PSU, remove the PSU from the bag.
  5. Using both hands, place the PSU in the PSU slot on the rear panel of the SRX1600. Slide the PSU straight into the chassis until the PSU is fully seated in the chassis slot. Ensure that the PSU faceplate is flush with the adjacent PSU faceplate.

  6. Tighten the captive screws on the lower edge of the PSU faceplate.
  7. Connect the power cables (see Connect the SRX1600 to Power).
