Installing SRP I/O and SRP Modules

SRP modules should be installed in specific slots in each router. See Table 5-2 for SRP module slot assignments.

Table 5-2 SRP module slot assignments
E-Series Router
Slot
ERX-14xx model
6 and 7
ERX-7xx model
0 and 1
ERX-310 router
0



Note: Because of different physical dimensions and switch fabric capabilities, SRP modules are not interchangeable between systems. For example, the 10-Gbps SRP module used in ERX-7xx/14xx models cannot be used in an ERX-310 router, and vice versa.



Note: Install the SRP I/O module before you install the SRP module; otherwise, the system diagnostics will fail.

Installing an SRP I/O Module

To install an SRP I/O module:

  1. Ground yourself by using an antistatic wrist strap or other device.
  2. With a Phillips screwdriver, loosen the captive screws that secure the blank faceplate covering the empty chassis slot, if present, and remove the faceplate.
  3. Remove the SRP I/O module from its antistatic bag.
  4. Slide the module into the chassis by placing it between the guides of the selected slot and pushing the module until it stops.


Note: See figures in Chapter 1, E-Series Overview, for module locations.

  1. Tighten the module's captive screws using a Phillips screwdriver. Turn both screws several times before tightening them completely to allow the module to sit correctly.

Installing an SRP Module

To install an SRP module:

  1. Ground yourself by using an antistatic wrist strap or other device.


Note: See figures in Chapter 1, E-Series Overview, for module locations.

  1. Choose the slot in which you want to install the module.
  1. With a Phillips screwdriver, loosen the captive screws that secure the blank faceplate covering the empty chassis slot, if present, and remove the faceplate.
  2. Remove the SRP module from its antistatic bag.
  3. Verify that the ejectors are in the open position, as shown in Figure 5-5.

  1. Slide 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 front of 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 one designed to hold the module. Also, be sure that you have aligned the top and bottom edges in the correct matching tracks.

  1. Insert the module into the backplane by simultaneously depressing both ejectors (as shown in Figure 5-5) and exerting forward pressure on the module.
  2. Tighten the module's captive screws using a Phillips screwdriver. Alternately turn each screw several times before tightening them completely to allow the module to sit correctly.
