Installing CFM Cards in the SRX3600 Services Gateway

 

The most common modules for the services gateway use the common form-factor module (CFM) format:

  • IOCs

  • NP-IOCs

  • SPCs

  • NPCs

Note

If your services gateway is part of an operating chassis cluster, you might be able to install additional SPCs in the clustered devices without shutting down both of the devices at the same time. This process, called in-service hardware upgrade (ISHU), eliminates the network downtime you would otherwise incur while adding SPCs. For more information, see Installing SPCs in an Operating SRX3600 Services Gateway Chassis Cluster.

To install a CFM card in the services gateway:

  1. Locate an eligible slot for the CFM in the services gateway. For information about the slot eligibility of various CFM types, see Hardware Component Locations in the SRX3600 Services Gateway Chassis. For information about the slot eligibility of specific CFMs, see the SRX1400, SRX3400, and SRX3600 Services Gateway Module Guide at https://www.juniper.net/documentation/.Note

    For the services gateway to meet NEBS and ETSI standards, it must not have any two SPCs installed side by side in the CFM slots in the front of the chassis (CFM slots 1 through 6). You can install SPCs side by side in the CFM slots in the rear of the chassis (CFM slots 7 through 12). See SRX3600 Services Gateway NEBS and ETSI Compliance for more information.

  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 SRX3600 Services Gateway.
  3. If you are installing a cold-swap-only CFM, power off the services gateway. See Field-Replaceable Units on the SRX3600 Services Gateway for a list of hot-swappable and cold-swap-only components.

    To power off the services gateway, press the Power button on the front panel of the Switch Fabric Board (SFB) for three to five seconds.

    The PWR LED blinks to show you that the services gateway is shutting down. Wait for the services gateway to shut down before you proceed to the next step.

  4. Place the CFM on an antistatic mat or remove it from its electrostatic bag.
  5. If the slot is covered by a blank panel, loosen the screws at each end of the blank panel and remove the blank panel from the services gateway.Note

    If a slot is not occupied by a card, you must install a blank panel to shield the empty slot and to allow cooling air to circulate properly through the services gateway.

  6. Orient the CFM so that the faceplate faces you. Slide the CFM all the way into the card cage until you feel resistance (Figure 1).
  7. Tighten the screws on either side of the card (Figure 1).

  8. If you are installing additional CFMs at this time, repeat steps 4 through 7, and then continue with the following steps to connect the appropriate cables.
  9. Insert the appropriate cables into the cable connector ports on each CFM as applicable. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on a loop helps to maintain its shape.
  10. If you inserted hot-swappable CFMs such as NP-IOCs without powering off the services gateway, bring each new CFM online and power it on by pressing its ONLINE button for five or more seconds.Note

    You may find it easiest to use a pen, screwdriver, or other tool to press the button.

  11. If you powered off the services gateway to install CFMs, power on the services gateway, as described in Powering On the SRX3600 Services Gateway.
  12. Check the OK/FAIL LED on each new CFM. The OK/FAIL LED on the CFM faceplate should blink green, then light steadily. If it is red, remove and reinstall the CFM. If the OK/FAIL LED remains red, the CFM is not functioning properly. Contact your customer support representative.
Warning

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