Upgrading CTP2000 Series Components for Memory Upgrades

 

Certain CTP2000 Series components need to be upgraded when RAM memory is increased, as required by certain JUNOS version updates. The affected modules and other components can be:

  • Processor module that contains the RAM card

  • CompactFlash card

  • Rear transition module (RTM) in case of the PP310 and PP332 processors

To install a CTP module:

  1. Ground yourself by using an antistatic wrist strap or other device, and connect it to one of the ESD grounding jacks, if available, or another grounding device.
  2. Choose the slot where you want to insert the module.
  3. With a Phillips screwdriver, loosen the screws that secure the blank filler panel covering the empty chassis slot, if present, and remove the filler panel.
  4. Remove the module from its antistatic bag, being careful not to touch module components, pins, leads, or solder connections.
  5. Verify that the ejectors are in the open position (facing outward).
  6. Guide the module into the chassis by placing it between the guides of the selected slot and pushing the module until it stops.

    The module stops sliding when the ejectors make contact with the chassis.

    Caution

    If you meet strong resistance when attempting to seat the module using the ejectors, remove it from the chassis, and confirm that the slot is designed to hold the component. Also, be sure that you have aligned the left and right edges in the correct matching tracks.

  7. Insert the module into the midplane by simultaneously pressing both ejectors inward and exerting forward pressure on the module. The small red release buttons should click into place.
  8. Tighten the module's captive screws using a Phillips screwdriver.Note

    Tighten the captive screws completely before installing an adjacent module so that proper electromagnetic interference (EMI) gasket compression occurs. Failure to do this can make it difficult to install adjacent modules.

  9. Go to Cabling a CTP Interface Module.
