To check the current setting of NVMRO:
Log in to the router as root.
1.
From the shell, type:
2.
root@host# sysctl kern.nvmro
kern.nvmro: 1
The value must be 0 to upgrade any files on the router. If the value is 0, proceed to
"Installing Software Upgrades from the Network" on page 16. If the value is 1, all
storage on the router is locked. You must reset the NVMRO switch located on the
rear transition module (RTM) to allow installation. See the LN1000–V Mobile Secure
Router Hardware Guide for the location of this switch.
Power off the system:
3.
root@host# cli request system power-off
When you see the following message, the system is safely powered off:
syncing disks... All buffers synced.
Uptime: 20h14m55s
Turning system power off
Follow the instructions in the LN1000–V Mobile Secure Router Hardware Guide to
access the RTM and toggle the NVMRO switch.
To clear NVMRO (allow writing/updating), turn the switch on.
To set NVMRO (lock all storage), turn the switch off.
Reinstall the RTM and boot the router.

To install software upgrades by downloading files to the router:
Clean up the system:
1.
root@host>request system storage cleanup
You are prompted to confirm deletion of a list of files:
Install the new package on the router, entering the following command:
2.
root@host>request system software add unlink no-copy source
Replace source with /pathname/package/package-name (for example,
/var/tmp/junos-in-9.6R2.1.tar.gz).
The
unlink
option removes the package at the earliest opportunity so that the router
has enough capacity to complete the installation.
The
option specifies that a software package is installed, but a copy of the
no-copy
package is not saved.
