Firmware Upgrade Instructions
Overview
These instructions guide you through the process of upgrading the firmware in
the device. The firmware upgrade will be either a standard release or a point

specifications of the existing version. A point release is reserved for
modifying firmware functionality to conform to the specifications of the
existing version.
A standard release is identified by a change in the R-number of the device
firmware identification (FID) string.
Existing firmware:
FID=SEL-411L-R100-V0-Z001001-Dxxxxxxxx, or
FID=SEL-411L-1-R100-V0-Z001001-Dxxxxxxxx

A point release is identified by a change in the V-number of the device FID
string.
