Replacing an SPC on the SRX1400 Services Gateway

 

There are two places an SPC can be installed in your SRX1400 Services Gateway:

  • You can install an SPC in the front-panel slot labeled 1 if you also install an NPC in the slot labeled 3. This combination of SPC and NPC replaces the full-width NSPC that is normally installed in the SRX1400 Services Gateway to perform both services processing and network processing functions.

  • If your SRX1400 Services Gateway is running Junos OS Release 12.1X44-D10 or later, you can install an SPC in slot 2. Doing so increases the services processing performance of the services gateway and increases its session capacity.

To replace an SPC:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to the SRX1400 Services Gateway.
  3. Loosen the captive screws at each end of the SPC faceplate.
  4. Grasp the SPC by its handle and slide it halfway out of the chassis.

  5. Place one hand underneath the SPC to support it and slide it completely out of the chassis. See Figure 1.Caution

    SPCs can become very warm during operation. Avoid contact with the heat sink on top of the card when you remove it to prevent personal injury.

  6. Place the SPC on the antistatic mat.
  7. Slide the replacement SPC into the slot until you feel resistance, and then press the SPC faceplate until it engages the connectors as shown in Figure 2.

  8. Tighten the captive screws on the left and right of the SPC.

When you power on the SRX1400 Services Gateway, the OK/FAIL LED on the SPC faceplate blinks green, then lights steadily indicating a normal operating condition.

Note

If the OK/FAIL LED is red, remove and reinstall the SPC. If the OK/FAIL LED remains red, the SPC is not functioning properly. Contact your customer support representative.

Warning

Never lift the services gateway using the handles on the front panels of the SPCs or other CFM cards. The handles might come off, causing the chassis to drop and inflicting possible grave injury.
