    Replacing the Standard CBs in the T320, T640, or T1600 Core Router

    Before you connect a T320, T640, or T1600 router to the JCS1200 platform, you must replace the standard control boards (CBs) with T-CBs. To replace the CBs with T-CBs:

    1. If the router is powered on, issue the request system halt both-routing-engines operational mode command from the console or other management device connected to the router. The command shuts down the Routing Engines cleanly, so their state information is preserved.
      user@host> request system halt both-routing-engines

      Wait until a message appears on the console confirming that the operating system has halted. For more information about the command, see request system halt.

    2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
    3. Switch all circuit breakers on the power supply faceplates to the off position (O).

      Note: The CBs and T-CBs are hot-removable and hot-insertable if the router contains redundant host subsystems. However, we recommend that you power off the router before you replace the CBs and T-CBs.

    4. Set the switches on each T-CB:
      • Set the chassis ID switch to 0. You must use the same chassis ID on each T-CB.
      • Set the M/S switch on the T-CB faceplate to S.
    5. Replace each CB with a T-CB. Use the standard replacement procedure described in the hardware guide for your router.
    6. You can optionally upgrade the Routing Engines in the router. To replace each Routing Engine, follow the standard replacement procedure described in the hardware guide for your router.
