Upgrading Junos in MX480 via USB

1. Upgrading Junos

1.   Procedure to upgrade the switch through USB:

2.   There are two routing engines for redundancy.

3.   Master routing-engine is on slot 0 and Backup routing-engine is on slot 1

4.   We have to install junos software package on each routing-engines separately

5.   First upgrade backup routing-engine and then upgrade master routing-engine

Note: Accidently if you upgrade Master first then you will loose communication with backup routing engine due to mismatch of Junos version.

In that case you have to loging to the master routing engine and issue below command to get into to backup routing engine:

> request routing-engine login other-routing-engine

Then apply the same procedure to install Junos on backup routing engine through USB.

ü  Login with root credentials

• Mount USB

% mount_msdosfs /dev/da1s1 /mnt

• Go to mount directory

% cd /mnt

• Copy junos software package to temp directory

% cp jinstall-11.4R7.5-export<press tab> /var/tmp

• To verify file, go to /var/tmp directory:

% cd /var/tmp

• To verify the package files

% ls

• Type cli and enter into operational mode

% cli

• Add the software package

> request system software add set /var/tmp/ jinstall-11.4R7.5-export<press tab>  no-copy

• Reboot the device
