Checking the Hardware Version of T640 or T1600 Components

 
  1. Checking the Hardware Version of the Control Boards

  2. Checking the Hardware Version of the Routing Engines

  3. Checking the Hardware Version of the Rear Fan Tray

  4. Checking the Hardware Version of the FPCs

Checking the Hardware Version of the Control Boards

The control board model number LCC-CB is required for the T4000 router.

The following control boards are not supported for the T4000 router:

  • CB-L-T

  • CB-T

To determine which model numbers of control boards are installed:

  1. Issue the show chassis hardware models command:

    In this example, the output shows that two CB-L-T control boards are installed.

    user@host> show chassis hardware models

    In this example, the output shows that two CB-T control boards are installed.

    In this example, the output shows that LCC-CB control boards are installed.

  2. If two LCC-CB control boards are not installed, order and install LCC-CB control boards.

Checking the Hardware Version of the Routing Engines

The Routing Engine model number RE-DUO-C1800-8G or RE-DUO-C1800-16G is required for the T4000 router. The following Routing Engines are not supported on the T4000 router:

  • RE-600-2048

  • RE-1600-2048

  • RE-A-2000-4096

To determine which model numbers of Routing Engines are installed:

  1. Issue the show chassis hardware models command:

    In this example, the output shows that two RE-600-2048 Routing Engines are installed.

    user@host> show chassis hardware models

    In this example, the output shows that two RE-A-2000-4096 Routing Engines are installed.

  2. If two RE-DUO-C1800-8G Routing Engines are not installed, order and install RE-DUO-C1800-8G Routing Engines.

Checking the Hardware Version of the Rear Fan Tray

The rear fan tray model number FAN-REAR-TXP-LCC has eight fans and is required to support the additional thermal power generation of the T4000 router.

The following fan trays do not provide sufficient cooling for the T4000 router:

  • RHTREARTRAY-T

  • FAN-REAR-TX-T640

  • FAN-R

  • FAN-REAR-T

To determine which version of the rear fan tray is installed:

  1. Issue the show chassis environment command:

    In this example, the output shows that the rear fan tray has five blowers, indicating that the RHTREARTRAY-T rear fan tray is installed. The last five lines of the output for the fans each include Blower in the description.

    user@host> show chassis environment

    In this example, the output shows that the rear fan tray has eight fans, indicating that FAN-REAR-TX-T640-S rear fan tray is installed. The last eight lines of the output for the fans each begin with Rear Tray and include fan in the description.

  2. Issue the show chassis hardware models command.

    In this example, the output shows that FAN-REAR-TX-T640 is installed.

    user@host> show chassis hardware models
  3. If the FAN-REAR-TXP-LCC rear fan tray is not installed, order and install the FAN-REAR-TXP-LCC rear fan tray.

Checking the Hardware Version of the FPCs

The FPCs supported for the T4000 router are listed in T4000 FPCs Supported. We recommend that you remove unsupported FPCs before installing the T4000 SIBs.

To determine which model numbers of FPCs are installed:

  1. Issue the show chassis hardware models command:

    In this example, the output shows that the T640-FPC2 and T640-FPC3 FPCs are installed.

    user@host> show chassis hardware models

    In this example, the output shows that T640-FPC2-E2, T640-FPC1-E2, T640-FPC3-E, and T1600-FPC4-ES FPCs are installed. The T1600-FPC4-ES FPCs are supported for the T4000 router. All other FPCs in the this example are currently unsupported for the T4000 router.

  2. Remove all unsupported FPCs. To minimize downtime, you can upgrade FPCs that are supported on both the T640 router or T1600 router and the T4000 router before the upgrade to a T4000 router. Note

    The following FPCs cannot be installed until all other hardware components for the T4000 router have been installed.

    • T1600-FPC4-ES FPCs cannot be installed on T640 routers that have not been upgraded. The T1600-FPC4-ES FPC is not supported on T640 routers.

    • T4000-FPC5-3D FPCs cannot be installed on T640 or T1600 routers that have not been upgraded.
