Maintaining the SRX Series Interface Modules

 

Required Tools and Parts for Replacing Interface Modules

The following tools and parts are required for replacing a Gigabit-Backplane Physical Interface Module (GPIM) or a Mini-Physical Interface Module on the services gateway:

  • Electrostatic bag or antistatic mat, for each component

  • Electrostatic discharge (ESD) grounding wrist strap

  • Flat-blade (–) screwdriver, approximately 1/8 in. (3 mm)

  • Phillips (+) screwdrivers, numbers 1 and 2

  • Blank panels (if no component will be installed)

Preventing Electrostatic Discharge Damage to the SRX300 Series and SRX550 High Memory Services Gateway

Many services gateway hardware components are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets. Observe the following guidelines to minimize the potential for electrostatic discharge (ESD) damage, which can cause intermittent or complete component failures:

  • Always use an ESD wrist strap or ankle strap, and verify that it is in direct contact with your skin.

    Caution

    For safety, periodically check the resistance value of the ESD strap. The measurement must be in the range of 1 to 10 Mohms.

  • When handling any component that is removed from the chassis, verify that the equipment end of your ESD strap is attached to one of the ESD points on the chassis.

  • Avoid contact between the component and your clothing. ESD voltages emitted from clothing can damage components.

  • When removing or installing a component, always place it component-side up on an antistatic surface, in an antistatic card rack, or in an electrostatic bag. See Figure 1. If you are returning a component, place it into an electrostatic bag before packing it.

Replacing Mini-Physical Interface Modules on the SRX300 Series and SRX550 High Memory Services Gateways

Before you begin, power off the services gateway.

Caution

The Mini-Physical Interface Modules (Mini-PIMs) available are not hot-swappable. You must power off the services gateway before removing or installing Mini-PIMs.

To maintain proper airflow through the services gateway, cover any empty Mini-PIM slot with a blank faceplate.

Caution

Do not remove a blank faceplate unless you are installing a Mini-PIM in the empty slot.

Removing a Mini-Physical Interface Module

To remove a Mini-PIM from the services gateway:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface on which you intend to place the Mini-PIM.
  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to the grounding point on the back of the device.
  3. Unplug the power adapter from the services gateway. Verify that the Power LED is off.
  4. Label the cables connected to the Mini-PIM so that you can later reconnect each cable to the correct Mini-PIM.
  5. Disconnect the cables from the Mini-PIM.
  6. If necessary, arrange the cables to prevent them from dislodging or developing stress points.
  7. Remove the screws on each side of the Mini-PIM faceplate using a 1/8-in. (3-mm) flat-blade (–) screwdriver.
  8. Grasp the screws on each side of the Mini-PIM faceplate and slide the Mini-PIM out of the services gateway.
  9. Place the Mini-PIM in the electrostatic bag or on the antistatic mat.
  10. If you are not reinstalling a Mini-PIM into the empty slot, install a blank faceplate over the slot to maintain proper airflow.

Installing a Mini-Physical Interface Module

To install a Mini-Physical Interface Module (Mini-PIM) in the services gateway.

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the grounding point on the back of the services gateway.
  2. Power off the services gateway by briefly pressing the Power button on the front panel. Wait for the Power LED to turn off before proceeding. Disconnect the services gateway from its power source.
  3. Remove the Mini-PIM from the electrostatic bag.
  4. Grasp the screws on each side of the Mini-PIM faceplate and align the notches in the connector at the rear of the Mini-PIM with the notches in the Mini-PIM slot in the device.Caution

    Slide the Mini-PIM straight into the slot to avoid damaging the components on the Mini-PIM.

  5. Slide the Mini-PIM in until it lodges firmly in the services gateway.
  6. Using a 1/8-in. (3-mm) flat-blade (–) screwdriver, tighten the screws on each side of the Mini-PIM faceplate.
  7. Insert the appropriate cables into the cable connectors on the Mini-PIM.
  8. If necessary, arrange the cables to prevent them from dislodging or developing stress points:
    • Secure the cables so that they are not supporting their own weight as they hang to the floor.

    • Place any excess cables out of the way in neatly coiled loops.

    • Use fasteners to maintain the shape of the cable loops.

  9. Reconnect the power adapter to the services gateway. Verify that the Power LED glows steadily green after you press the power button.
  10. Verify that the Mini-PIM LED on the system dashboard glows steadily green to confirm that the Mini-PIM is online.

Removing a Blank Mini-Physical Interface Module Faceplate

To remove a blank faceplate from the SRX Series Services Gateway:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the services gateway.
  2. If the device is powered on, power off the device. Verify that the Power LED is off.
  3. Loosen the screws on each side of the faceplate.
    • On faceplates with handles, use a 1/8-in. (3-mm) flat-blade (–) screwdriver to loosen but not remove the captive screws.

    • On faceplates without handles, use a Phillips number 1 screwdriver to remove the noncaptive screws.

  4. Remove the faceplate.

Installing a Blank Mini-Physical Interface Module Faceplate

To install a blank faceplate on the SRX Series Services Gateway:

  1. Align the captive screws on the blank faceplate with the screw holes on the chassis.
  2. Tighten the screws on each side of the faceplate.
    • On faceplates with handles, use a 1/8-in. (3-mm) flat-blade (–) screwdriver to tighten the captive screws.

    • On faceplates without handles, use a Phillips number 1 screwdriver to tighten the noncaptive screws.
