WP 12069 Backup CDS GC router install
As per WP 12069 I have installed a new system in the daq-2 rack slot 39, above the existing router.

I have hooked it up to the admin vlan and have ipmi enabled on it.  This is all of the network connectivity that will be enabled today.  I have installed a solar flare 10g card into the system for its eventual connection to the core switch.  I had to replace one power supply which had failed.  I pulled the replacement power supply from a spare unit on the shelves.

Install notes:
 * I am installing the same version of vyos on this router as is used on the current router.
   * the test stand log from the last time I did this (https://alog.ligo-la.caltech.edu/TST/index.php?callRep=15381).
 * I created a bootable thumb drive from the install iso and booted into a live image mode.
 * After booting to the thumbdrive and logging in I issued the 'install image'
   * select the local disk (sda)
   * automatically partition to a 40GB size
 * Default settings otherwise
 * After install, issue the reboot command.

To transfer the config over, I formatted a usb thumb drive as a ext4 filesystem and mounted it to /mnt.  I then entered config mode, issued a 'save config_3_sep_2024' and exited out.  I copied the /config/config_3_sep_2024 file to /mnt and unmounted mnt.  After moving the drive to the new router, I became root, mounted /mnt copied the new config file to /home/vyos/config_3_sep_2024 and changed it's ownership to the vyos user.  At this time I also updated the config to have the correct hw mac addresses for this box. Then as the vyos user I entered config mode, issued a 'load /home/vyos/config_3_sep_2024', then 'commit', then 'save' to make the config persists.

I rebooted to make sure the config was properly saved.  It took me two tries as the first time I only committed the change and did not save it.

I have installed an optic on the router and powered it of.  I will provide documentation for the operator on how to switch over to this router if there is a failure.  The basic procedure is:

 * power off the old router (rack 5, slot 37) using the power button on the front
 * go to the back of the rack
   * move the pink cable from the older router to the the new one (the port is labeled GB1 on both systems).
   * move the fiber from the older router to the new one (there is presently only 1 optic in each so there should be no confusion).
 * go back to the front of the rack and power on the new router (rack 5, slot 39) using the power button on the front.
