Connecting the JCS 1200 Platform to a T-series Routing Platform

You can connect up to three of the following T-series routing platforms running JUNOS Release 9.2 or later to the JCS 1200 platform: T320 router, T640 routing node, and T1600 routing node. The following procedures describe connecting the JCS 1200 platform to a T-series routing platform:

Replacing the Standard CBs in the T-series Routing Platform

Before you connect an offline T-series routing platform to the JCS 1200 platform, you must replace the standard control boards (CBs) with T-CBs. To replace the CBs with T-CBs:

  1. If the routing platform is powered on, issue the request system halt both-routing-engines operational mode command from the console or other management device connected to the routing platform. 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 the JUNOS System Basics and Services Command Reference.

  2. Attach an electrostatic discharge (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 routing node contains redundant host subsystems. However, we recommend that you power off the routing platform 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 routing platform.
  6. You can optionally upgrade the Routing Engines in the routing platform. To replace each Routing Engine, follow the standard replacement procedure described in the hardware guide for your routing platform.

Connecting an Offline T-series Routing Platform to the JCS 1200 Platform

After you replace the CBs with T-CBs, you connect each T-CB on the T-series routing platform to each switch module on the JCS 1200 platform. Figure 1 shows the location of the switch modules on the JCS 1200 platform.

To connect the T-CBs (see Figure 2):

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Plug an ETH adapter into the top RJ-45 port (labeled 1) of switch module 1 on the JCS 1200 platform.
  3. Connect one end of a UTP Category 5 cable to the ETH adapter.
  4. Plug the other end of the cable into the port labeled CIP on T-CB-0. Dress the cable appropriately.

    Note: The RJ-45 port labeled AUX on a T-CB is reserved for future use.

  5. If you installed a redundant switch module into switch module bay 2:
    1. Plug an ETH adapter into the top RJ-45 port (labeled 1) of switch module 2 on the JCS 1200 platform.
    2. Connect one end of a UTP Category 5 cable to the ETH adapter.
    3. Plug the other end of the cable into the port labeled CIP on T-CB-1. Dress the cable appropriately.

  6. Repeat 2 through 5 to connect up to two additional T-series routing platforms to RJ-45 ports labeled 2 and 3 on the JCS 1200 switch module.

    Note: To connect more than one T-series routing platform, each routing platform must run JUNOS Release 9.2 or later.

Note: A switch module has six external 1000Base-T Ethernet ports for 10/100/1000 Mbps connections to external Ethernet devices, such as backbones, end stations, and servers. These ports are identified as EXT1, EXT2, EXT3, EXT4, EXT5, and EXT6 in the switch configuration menus and are labeled 1 through 6 (from top to bottom) on the JCS 1200 switch module.

Note: The connections between the switch modules and the T-CBs are proprietary Ethernet connections. Do not attempt to connect these components through a switch or hub.

Powering On the T-series Routing Platform

After you have connected the control planes between the T-series routing platform and the JCS 1200 platform, power on the routing platform, monitor the boot process, and verify the connections. Follow this procedure:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Switch the circuit breakers on one of the power supplies to the on position (|) and observe the LEDs on the power supply faceplate. If the power supply is correctly installed and is functioning properly, the DC OK LED lights steadily, and the CB ON LED blinks momentarily, then lights steadily.

    Note: After powering off a power supply, wait at least 60 seconds before powering it back on. After powering on a power supply, wait at least 60 seconds before powering it off.

    If the system is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, first issue the CLI request system halt command.

    After a power supply is powered on, it can take up to 60 seconds for status indicators—such as the output status LEDs on the power supply, the show chassis command display, and messages on the LCD on the craft interface—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

  3. Repeat Step 2 for the remaining power supply.
  4. On an external management device connected to the console or auxiliary port of the CIP, monitor the startup process to verify that the system has booted properly.

Note: You do not need to reboot the JCS 1200 platform after the routing platform has booted.
