Step 3: Install Modules and Other Components

Module Installation Overview

In CTP2000 series platforms, interface modules can be installed in the front and rear of the device. Rear transition modules (RTMs) are located in the rear of the device.

Interface modules are not hot-swappable.

In CTP2000 series platforms, slot numbering starts at the top of the chassis with slot 0.

Protect Modules and Slots

The CTP2056 has an ESD (electrostatic discharge) grounding jack located in the rear lower-left corner of the chassis near the power switch. To prevent damage from electrostatic discharge, wear an antistatic wrist strap and connect it to one of the jacks when handling components. There are no ESD jacks on the other CTP platforms, so you must use another grounding device.

To protect the modules, components, and slots when installing components, observe the following guidelines:

Caution: When handling components, use an antistatic wrist strap connected to an appropriate grounding device. This action helps to protect the module from damage by electrostatic discharge.

Caution: Always handle a module by its edges. Do not touch the components, pins, leads, or solder connections.

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

Caution: Be sure to cover every empty slot with a blank filler panel to protect the device from dust or other foreign substances and to ensure proper device cooling.

Caution: Do not discard the antistatic bag. When a module is not in use, store it in an antistatic bag.

Required Tools and Safety Items for Installation

You need the following tools to install a CTP module:

  • Phillips screwdriver
  • Flathead screwdriver
  • ESD wrist strap or other grounding device

Safety Guidelines for Installing Modules

Before and during the installation process, observe the following warnings:

Warning: Do not work on the device or connect or disconnect cables during lightning activity.

Warning: Be sure circuit breakers for the power source are in the OFF position before attaching power cables.

Warning: Remove jewelry (including rings, necklaces, and watches) before working on equipment that is connected to power lines. Metal objects heat up when connected to power and ground and can cause serious burns or become welded to the terminals.

Warning: Do not insert any metal object, such as a screwdriver, into an open slot or the midplane. Doing so can cause electric shock and serious burns.

Warning: Never attempt to repair parts of modules yourself. Only trained customer service personnel are authorized to service parts. Call Juniper Networks Customer Service to make arrangements to return defective modules for repair.

Install a CTP Interface Module, Processor Module, or Clock Module

To install a module:

  1. Ground yourself by using an antistatic wrist strap or other device, and connect it to one of the ESD grounding jacks.
  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.

Install a CompactFlash Card

On the CTP2000 series devices with the new PP833 processor, the CompactFlash card is installed on the processor itself (which may be located under an installed PMC card), which prevents insertion or removal of the CompactFlash card until the PMC card is removed. On the CTP2000 series devices with the PP310 and PP332 processors, the CompactFlash card is installed on the processor rear transition module (RTM). Some CTP devices may ship with a CompactFlash card already installed.

To remove or install the CompactFlash card for the CTP2000 series devices with the new PP833 processor (see Figure 1):

  1. Power off the unit.
  2. If installed, remove the PP833 PMC card by unscrewing the retaining screws and pushing the extractors outward with the latching buttons depressed.
  3. You can then remove or install the CompactFlash card in the flash socket.
  4. If being used, reinstall the PP833 PMC card into the chassis, and secure the retaining screws.

To remove and reinstall the CompactFlash card for the CTP2000 series devices with the PP310 and PP332 processors:

  1. Power off the unit.
  2. Remove the RTM by unscrewing the retaining screws and pushing the extractors outward with the latching buttons depressed.
  3. Verify that the CompactFlash card is installed.
  4. Remove the CompactFlash card–retaining screw and nut. You can then remove or install the CompactFlash card in the flash socket.
  5. Reinstall the CompactFlash card–retaining screw and nut.
  6. Reinstall the processor RTM into the chassis, and secure the retaining screws.

Install a PMC Module

The PMC module is mounted onto the processor module and can be installed or replaced in the field. Figure 3 displays the location of the PMC module.

Figure 3: Installing a PMC Module

Installing a PMC Module

To install a PMC module:

  1. Confirm that the device is powered off.
  2. Remove the processor module by unscrewing the retaining screws and pushing the extractors outward with the latching buttons depressed.
  3. A shield may have been installed in the PMC slot of the processor’s front panel. Remove this shield by gently pushing it out from behind the panel.
  4. The PMC module has four screws. Two of the screws are secured to standoffs, and two are attached to the front assembly of the PMC module. Remove the two screws secured to the standoff, leaving the standoff attached to the PMC module. Remove the two screws on the front assembly located on the side with the standoffs. The front assembly should remain attached to the PMC hardware. Keep the screws for reattachment.
  5. Align the PMC module with the printed circuit board connectors toward the processor board and with the fiber connectors inserted through the processor’s front panel. Align the alignment post on the processor module with the PMC module’s alignment hole.
  6. Gently press the PMC module into the processor module.
  7. From the back of the processor module, use the four Phillips head screws to secure the two PMC standoff posts and PMC front assembly to the processor module.
  8. Reinstall the processor.

Install SFPs

This section describes how to install small form-factor pluggable transceivers (SFPs) on interface modules that support these devices. In the current release, the CTP-FX2000GE-UPG supports SFPs.

You can replace the SFPs without disabling the interfaces or removing the module from the device.

To install SFPs:

  1. Ground yourself by using an antistatic wrist strap or other device, and connect it to an ESD grounding jack.
  2. Identify the following items on the SFP (Figure 4):
    • The connection circuitry on the base
    • The cable connectors on the front (which are protected by a dust cover)

    Figure 4: Representative SFP

    Representative SFP

    Caution: Be sure to position the SFP correctly before you install it.

  3. Hold the SFP so that:
    • The connection circuitry is adjacent to the module's faceplate.
    • The cable connectors are visible when you install the SFP.
  4. Slide the SFP as far as you can into the module until the SFP clicks into place.

    If the SFP does not slide smoothly into the module, make sure that the orientation of the SFP is correct.

  5. Gently pull the SFP to confirm that it is inserted correctly.

    If the SFP comes out of the slot when you pull it, repeat Step 4.

  6. Remove the dust cover that protects the cable connectors.
  7. Connect the new cables to the SFP.
