Determining the
Firmware Version
To determine the firmware version, view the status report by using the serial
port STATUS command or the front panel. The status report displays the
Firmware Identification (FID) label.
The firmware version will be either a standard release or a point release. A
standard release adds new functionality to the firmware beyond the
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-751-R100-V0-Z001001-Dxxxxxxxx
Standard release firmware:
FID=SEL-751-R101-V0-Z001001-Dxxxxxxxx
A point release is identified by a change in the V-number of the device FID
string.
Existing firmware:
FID=SEL-751-R100-V0-Z001001-Dxxxxxxxx
Point release firmware:
FID=SEL-751-R100-V1-Z001001-Dxxxxxxxx
Table A.1 lists the firmware versions, a description of modifications, and the
