Default calibration values for releases before v4.2

To deploy the values from tables below you should get access to the WR Switch shell. You can do
this either by using the USB-UART management port on the front panel, or SSH-ing through the
management Ethernet port.
If you run an old firmware version (< 4.0) the filesystem of the switch is mounted read-only.
You have to remount it before editing config files:

wrs# wrfs_mnt.sh rw

and go back to read-only mode once you are done with your changes:

wrs# wrfs_mnt.sh ro

Don't forget to reboot the switch to apply new calibration parameters:

wrs# reboot

You can edit /wr/etc/sfp_database.conf and /wr/etc/wrsw_hal.conf files using vi
editor. Please use values from the tables below depending on the hardware and gateware version
you use. However, bear in mind that those numbers are valid only for release binaries you
can download from ohwr.org. If you re-synthesize the gateware you have to perform calibration
procedure to find new values.
