Maintaining the SRX5800 Power System

Maintaining SRX5800 Firewall Power Supplies

Purpose

For optimum firewall 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 is similar to the following:

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

  • Routinely check the status LEDs on the power supply faceplates and the craft interface to determine if the power supplies are functioning normally.

  • Check the red and yellow alarm LEDs on the craft interface. Power supply failure or removal triggers an alarm that causes one or both of the 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.

To replace an AC or High-Voltage Second-Generation Universal (HVAC/HVDC) power supply, perform the following procedures:

Removing an SRX5800 Firewall AC Power Supply or High-Voltage Second-Generation Universal (HVAC/HVDC) Power Supply

Before you remove a power supply, be aware of the following:

Note:

The minimum number of power supplies must be present in the firewall at all times.

CAUTION:

To maintain proper cooling and prevent thermal shutdown of the operating power supply unit, each power supply slot must contain either a power supply or a blank panel. If you remove a power supply, you must install a replacement power supply or a blank panel shortly after the removal.

Note:

After powering off a power supply, wait at least 60 seconds before turning it back on.

Before you begin to remove the AC power supply:

Ensure that you have the following available:

  • ESD grounding strap

To remove an AC power supply (see Figure 1):

  1. Switch off the dedicated customer site circuit breaker for the power supply, and remove the power cord from the AC power source. If the firewall is equipped with high-capacity AC power supplies, remove both of the power cords for the power supply. Follow the ESD and disconnection instructions for your site.
  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Move the AC input switch on the chassis above the AC power supply to the off  (O) position. If the firewall is equipped with high-capacity AC power supplies you must also move the AC input switch on the power supply itself to the off  (O) position.
  4. While grasping the handle on the power supply faceplate with one hand, use your other hand to pull the spring-loaded locking pin in the release lever away from the chassis and turn the release lever counterclockwise until it stops.
  5. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.
  6. Pull the power supply straight out of the chassis. The power supply can weigh up to 12 lb (5.5 kg). Be prepared to accept its full weight.

Before you begin to install an AC high-voltage second-generation universal (HVAC/HVDC) power supply:

Ensure that you have the following available:

  • ESD grounding strap

To install an AC the high-voltage second-generation universal (HVAC/HVDC) power supply:

  1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. If you have not already done so, move the AC input switch in the chassis above the empty power supply slot to the off  (O) position.
  3. For each high-capacity or high-capacity second-generation AC power supply, move the input mode switch to position 0 for one feed or position 1 for two feeds (see Figure 5). We recommend that you use two AC power feeds and set the mode input switch to 1.
    Figure 5: High-Capacity AC Power Supply Input Mode Switch High-Capacity AC Power Supply Input Mode Switch
    Figure 6: High-Capacity Second-Generation AC Power Supply Input Mode Switch High-Capacity Second-Generation AC Power Supply Input Mode Switch
    Note:

    Do not use a pencil to set the mode switch, because fragments can break off and cause damage to the power supply.
  4. If you are installing a high-capacity, or high-capacity second-generation AC, or high-voltage second-generation universal (HVAC or HVDC) power supply, move the AC input switch on the faceplate of the power supply itself to the off (O) position.
  5. Ensure that the release lever below the empty power supply slot is locked in the counterclockwise position (see Figure 7).

    If necessary, pull the spring-loaded locking pin in the release lever away from the chassis and turn the release lever counterclockwise until it stops. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.

  6. Using both hands, slide the power supply straight into the chassis until the power supply is fully seated in the chassis slot. The power supply faceplate should be flush with any adjacent power supply faceplates.

    The small tab on the metal housing that is controlled by the release lever must be inside of the corresponding slot at the bottom of the power supply (see Figure 7). This tab is used to pull the power supply down in the chassis slot, prior to removing the power supply.

  11. If you are installing a high-capacity, or high-capacity second-generation AC, or high-voltage second-generation universal (HVAC or HVDC) power supply, move the AC input switch on the faceplate of the power supply itself to the on (1) position.
  12. Verify the following LED indications for each installed power supply:

    • For standard-capacity AC power supplies, verify that the AC OK and DC OK LEDs light steadily and the PS FAIL LED is not lit.

    • For high-capacity AC power supplies, verify that the DC OK LED lights steadily and the PS FAIL LED is not lit. In addition, the AC-1 OK LED should light green steadily if the upper AC feed (on the chassis above the power supply) is connected and receiving power, and the AC-2 OK LED should light green steadily if the lower AC feed (on the power supply itself) is connected and receiving power.

    • For high-capacity second-generation AC power supplies, verify that the DC OK LED lights steadily and the PS FAIL LED is not lit. In addition, the IN-1 OK LED should light green steadily if the upper AC feed (on the chassis above the power supply) is connected and receiving power, and the IN-2 OK LED should light green steadily if the lower AC feed (on the power supply itself) is connected and receiving power.

    • For high-voltage second-generation universal (HVAC/HVDC) AC power supplies, verify that the INP OK and DC OK LEDs light steadily and the PS FAIL LED is not lit.

    Note:

    After a power supply is powered on, it can take up to 60 seconds for status indicators—such as the status LEDs on the power supply and the show chassis command display—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

    If any of the status LEDs indicates that the power supply is not functioning normally, repeat the installation and cabling procedures.

      Figure 14: Connecting DC Power to a High-Capacity DC Power Supply Connecting DC Power to a High-Capacity DC Power Supply
    CAUTION:

    Ensure that each power cable lug seats flush against the surface of the terminal block as you are tightening the nuts. Ensure that each nut is properly threaded onto the terminal stud. The nut should be able to spin freely with your fingers when it is first placed onto the terminal stud. Applying installation torque to the nut when improperly threaded may result in damage to the terminal stud.

    CAUTION:

    The maximum torque rating of the terminal studs on the DC power supply is 36 in-lb. (4.0 Nm). The terminal studs may be damaged if excessive torque is applied. Use only a torque-controlled driver or socket wrench to tighten nuts on the DC power supply terminal studs.

    Note:

    The DC power supplies in slots PEM0 and PEM1 must be powered by dedicated power feeds derived from feed A, and the DC power supplies in PEM2 and PEM3 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.

  13. For standard-capacity DC power supplies, secure each DC power cable to its strain relief bracket as follows:
    1. Loosen the captive screw on the cable restraint on the lower edge of the power supply faceplate.

Upgrading an SRX5800 Firewall from Standard-Capacity to High-Capacity Power Supplies

You can replace the standard-capacity power supplies in the SRX5800 Firewall with either two or four high-capacity power supplies of the same input type (AC or DC). Two high-capacity power supplies provide adequate power for a fully loaded chassis; installing four high-capacity power supplies provides redundancy in case one power supply in either zone fails. You do not need to power off the device to upgrade to high-capacity power supplies.

Note:

The firewall cannot be powered from standard-capacity and high-capacity power supplies simultaneously. The one exception is during the process of replacing standard-capacity power supplies with high-capacity power supplies, when it is permissible to have both types installed briefly.

CAUTION:

The firewall cannot be powered from AC and DC power supplies simultaneously. The first type of power supply detected by the firewall when initially powered on determines the type of power supply allowed by the firewall. All installed power supplies of the other type are disabled by the firewall. If you install a power supply of the other type while the firewall is operating, the firewall disables the power supply and generates an alarm.

The following procedures describe how to upgrade from standard-capacity power supplies to high-capacity power supplies of the same input type (AC or DC) without interrupting power to the firewall components. Choose the procedure that matches your firewall configuration:

To upgrade a firewall that has three or four standard-capacity AC power supplies to two or four high-capacity AC power supplies:

CAUTION:

Limit to five minutes or less the time during which standard-capacity AC power supplies and high-capacity AC power supplies are installed in the firewall at the same time.

  1. Ensure that the firewall is running Junos OS Release 10.4 or later. Earlier Junos OS releases do not support high-capacity AC power supplies.
  2. If you have not already done so, replace both standard-capacity fan trays with high-capacity fan trays. Also replace the standard-capacity air filter with a high-capacity air filter. For more information, see Replacing an SRX5800 Firewall Fan Tray and Replacing the SRX5800 Firewall Air Filter.
  3. Check the LEDs on all of the installed power supply faceplates to ensure that they are operating properly.
  4. If there are four standard-capacity AC power supplies installed, remove the standard-capacity AC power supply installed in the PEM0 slot. See Removing an SRX5800 Firewall AC Power Supply for instructions on removing AC power supplies. If there are only three standard-capacity AC power supplies installed in the firewall, proceed to the next step.
  5. Install a high-capacity AC power supply in the vacant slot in the back of the chassis. See Installing an SRX5800 Firewall AC Power Supply for instructions on installing AC power supplies.
  6. Check the LEDs on the high-capacity AC power supply faceplate to ensure that it is operating properly.
  7. Identify the slot for the next high-capacity AC power supply:

    • If the slot you installed the power supply into in 5 is PEM0 or PEM2, install the next high-capacity AC power supply in either slot PEM1 or PEM3

    • If the slot you installed the power supply into in 5 is PEM1 or PEM3, install the next high-capacity AC power supply in either slot PEM0 or PEM2

  8. Remove the standard-capacity AC power supply from the slot you identified in step7. See Removing an SRX5800 Firewall AC Power Supply for instructions on removing AC power supplies.
