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

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:

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Determine whether the host subsystem is functioning as the master or as the backup, using one of these methods:
   • Check the Routing Engine 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 CLI command. The master Routing Engine is designated Master in the Current state field:
     user@host> show chassis routing-engine

     Routing Engine status:   
       Slot 0:
         Current state                 Master
     ...
      

3. If the host subsystem is functioning as the master, switch it to backup using the request chassis routing-engine master switch command.
4. From the master Routing Engine, issue the request system power-off other-routing-engine to power down the backup Routing Engine.
5. Verify that the Online, DISK1, and CF LEDs on the backup Routing Engine faceplate are off.
6. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
7. Remove the cover from the Routing Engine slots by loosening the captive screws on the corners of the cover (using a Phillips (+) screwdriver, number 2).

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

8. Press the eject button on the right side of the DISK 1 slot to release the SSD.
9. The SSD pops partially out of the slot. Grasp the SSD and carefully slide it completely out of the slot.
10. Place the SSD on the antistatic mat.

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

1. Insert the SSD into the DISK 1 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 and tighten the screws on the corners of the cover to secure it to the Routing Engine (using a Phillips (+) screwdriver, number 2).
4. From the master Routing Engine, issue the request system power-on other-routing-engine command to power on the Routing Engine.

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

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.

Note: For more information about the commands for this procedure, see the Junos OS System Basics and Services Command Reference .

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 command to partition the SSD.
3. Issue the request system reboot command to reboot the router's software. The SSD will now be the secondary boot device.
4. Issue the show system boot-messages command to verify that boot order is correct. The output lists the devices mounted. The SSD is located at ad1.
5. Issue the request system snapshot command to back up the currently running and active file system partitions on the router to standby partitions that are not running.
6. Wait until a message appears on the console confirming that the snapshot partition procedure is complete.
