Replacing a Solid-State Disk in a TX Matrix Plus Routing Engine

 Note

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 TX Matrix Plus Routing Engine

To prepare to replace the solid-state disk in a TX Matrix Plus Routing Engine:

  1. Issue the show chassis routing-engine CLI command to determine the master Routing Engine for all routers in the routing matrix. The master Routing Engine is designated Master in the Current state field. Note

    The master Routing Engine for all routers in the routing matrix must be in the same slot.

    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
  2. If the master host subsystem for any T1600 router lcc 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 switches the master routing engine in the T1600 router.

    user@host> request chassis routing-engine master switch lcc 0
  3. If the host subsystem on the TX Matrix Plus is functioning as the master, switch it to backup using the request chassis routing-engine master switch all-chassis command.Note

    This switches the master routing engine in the TX Matrix plus router and all attached T1600 routers.

  4. From the master Routing Engine, issue the request system power-off sfc 0 other-routing-engine to power down the backup Routing Engine in the TX Matrix plus router.Note

    It is not necessary to power down the Routing Engines in the attached T1600 routers.

Removing a Solid-State Disk in a TX Matrix Plus Routing Engine

The solid-state disk (SSD) is located in the slot labeled Disk 1 on the Routing Engine faceplate.

Note

The Disk 2 slot is not currently supported.

To remove an SSD from a Routing Engine in a TX Matrix Plus router (see Figure 1):

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. Verify that the Online, Disk 1, 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 Disk 1 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 TX Matrix Plus Routing Engine

To install an SSD in a Routing Engine (see Figure 2):

  1. Insert the SSD into the Disk 1 slot on the Routing Engine, with the logo facing right.Caution

    Be sure to insert the SSD with the label facing right. 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, issue the request system power-on sfc 0 other-routing-engine command to power on the Routing Engine.

Copying the Junos OS to the Solid-State Disk in a TX Matrix Plus 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. Issue the request system partition hard-disk sfc 0 command to partition the SSD. For more information, see request system partition hard-disk.
  3. Wait until a message appears on the console confirming that the partition procedure is complete.
  4. Issue the request system reboot sfc 0 command to reboot the router's software. For more information, seerequest system reboot.
  5. Issue the request system snapshot sfc 0 command to back up the currently running and active file system partitions on the router to standby partitions that are not running. For more information, see request system snapshot.
  6. Wait until a message appears on the console confirming that the snapshot procedure is complete.
  7. Issue the request system reboot sfc 0 command again to reboot the router's software. For more information, seerequest system reboot.
  8. Issue the show system boot-messages sfc 0 command to verify that the SSD is listed as the secondary boot device. The output lists the devices mounted. The SSD is located at ad1. For more information, see show system boot-messages.
