Replacing a Solid-State Disk in a T1600 RE-C1800 Routing Engine

 Note

For routers in a routing matrix, this procedure is supported for Junos OS Release 11.4R3 and later, or Junos OS Release 12.1R2 and later.

Preparing to Replace a Solid-State Disk in a T1600 RE-C1800 Routing Engine

To prepare to replace a solid-state disk in a T1600 RE-C1800 Routing Engine:

  1. Determine whether the host subsystem is functioning as the master or as the backup, using one of these methods:
    • For standalone T1600 routers:

      • Check the host subsystem LEDs on the craft interface. If the green MASTER LED is lit, the corresponding host subsystem is functioning as the master.

      • Check the MASTER LED on the control board. If the blue MASTER LED is lit, the host subsystem is functioning as the master.

      • Issue the following command:

        user@host> show chassis routing-engine

        In this example, the Routing Engine in Slot 0 is designated Master in the Current state field.

    • For T1600 routers in a routing matrix, verify that the master Routing Engines for all routers in the routing matrix are in the same slot.

      To determine whether the host subsystems are functioning as the master or as the backup:

      • Issue the show chassis routing-engine CLI command from the TX Matrix Plus router.

        The master Routing Engine is designated Master in the Current state field. In this example, the Master Routing Engine is in Slot 0 for both sfc0-re0 and lcc0-re0.

        user@host> show chassis routing-engine

        In this example, the Master Routing Engine is in Slot 0 for sfc0-re0 but Slot 1 for lcc0-re0.

        user@host> show chassis routing-engine

      If the master host subsystem for any T1600 router lcc in a routing matrix is in a different slot from the master host subsystem for the TX Matrix Plus router sfc, use the request chassis routing-engine master switch lcc command to correct the problem.

      Note

      This command switches the master Routing Engine in the T1600 router.

      user@host> request chassis routing-engine master switch lcc 0
  2. If the host subsystem is functioning as the master, switch it to backup.
    • For a standalone T1600 router, issue the request chassis routing-engine master switch command.

    • For a T1600 router in a routing matrix, issue the request chassis routing-engine master switch all-chassis command from the TX Matrix Plus router.

  3. From the master Routing Engine, power down the backup Routing Engine.
    • For a standalone T1600 router, issue the request system power-off other-routing-engine command.

    • For a T1600 router in a routing matrix, issue the request system power-off lcc number other-routing-engine command from the TX Matrix Plus router.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

Removing a Solid-State Disk in a T1600 RE-C1800 Routing Engine

The solid-state disk (SSD) is located in the slot labeled DISK1 on the Routing Engine faceplate.

Note

The DISK2 slot is not currently supported.

To remove an SSD from a Routing Engine:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. Verify that the Online, DISK1, and CF LEDs on the backup Routing Engine faceplate are off.
  3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  4. Using a Phillips (+) screwdriver, number 2, loosen the captive screws on the corners of the cover.
  5. Remove the cover from the Routing Engine slots. Caution

    Do not remove the cover if any of the LEDs on the Routing Engine faceplate are lit.

  6. Press the eject button on the right side of the DISK1 slot to release the SSD.
  7. The SSD pops partially out of the slot. Grasp the SSD and carefully slide it completely out of the slot.
  8. Place the SSD on the antistatic mat.

Installing a Solid-State Disk in a T1600 RE-C1800 Routing Engine

To install an SSD in a Routing Engine:

  1. Insert the SSD into the DISK1 slot on the Routing Engine, with the logo facing down.Caution

    Be sure to insert the SSD with the label facing down. Inserting the SSD incorrectly might damage the Routing Engine.

  2. Slide the SSD into the slot until you feel resistance, carefully ensuring that it is correctly aligned.
  3. Reinstall the Routing Engine cover. Using a Phillips (+) screwdriver, number 2, tighten the screws on the corners of the cover to secure it to the Routing Engine .
  4. From the master Routing Engine, power on the Routing Engine.
    • For a standalone T1600 router, issue the request system power-on other-routing-engine command.

    • For a T1600 router in a routing matrix, issue the request system power-on lcc number other-routing-engine command from the TX Matrix Plus router.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

Copying Junos OS to the Solid-State Disk in a T1600 RE-C1800 Routing Engine

After installing a solid-state disk (SSD) for the first time, you must copy the software from the Routing Engine's CompactFlash card to the SSD.

To copy software to the SSD:

  1. On the console or other management device connected to the Routing Engine, enter CLI operational mode.
  2. Partition the SSD. See request system partition hard-disk.
    • For standalone T1600 routers, issue the request system partition hard-disk command.

    • For T1600 routers in a routing matix, issue the request system partition hard-disk lcc number command.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

  3. Wait until a message appears on the console confirming that the partition procedure is complete.
  4. Reboot the router's software.
    • For standalone T1600 routers, issue the request system reboot command.

    • For T1600 routers in a routing matrix, issue the request system reboot lcc number command.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

  5. Back up the currently running and active file system partitions on the router to standby partitions that are not running.
    • For standalone T1600 routers, issue the request system snapshot command.

    • For T1600 routers in a routing matrix, issue the request system snapshot lcc number command.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

  6. Wait until a message appears on the console confirming that the snapshot procedure is complete.
  7. Reboot the router's software again.
    • For standalone T1600 routers, issue the request system reboot command.

    • For T1600 routers in a routing matrix, issue the request system reboot lcc number command.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

  8. Verify that the SSD is listed as the secondary boot device. The output lists the devices mounted. The SSD is located at ad1.
    • For standalone T1600 routers, issue the show system boot-messages command.

    • For T1600 routers in a routing matrix, issue the show system boot-messages lcc number command.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).
