GE tracking number: 606-10
C,B Corrected firmware to prevent an unexpected restart due to MMS frames with corrupted CLNP header
Products: All with the IEC 61850 software option
Impacted firmware: All to 6.05, 7.00 to 7.25
Corrected firmware: 5.84, 6.06, 7.26
Workaround: None
Description: MMS frames with a corrupted Connectionless Network Protocol (CLNP) header can cause an
unexpected restart of the relay. The new releases fix the issue.
GE tracking number: 606-6
Network Stability System – N60
B
Changed the initialization process to prevent unnecessary reboot after a firmware upgrade
Products: N60
Impacted firmware: All to 6.05, 7.00 to 7.20
Corrected firmware: 5.84, 6.06, 7.21
Workaround: None
Description: When upgrading firmware, UR devices normally execute a single reboot at the end of the
upgrade process.
N60 devices can reboot twice at the end of the process because of minor initialization issues. Once the
second reboot completes, the N60 is back to normal operation.
The corrected versions ensure that the firmware upgrade process is completed with the first reboot (no
second reboot is required).

The “Equipment Mismatch” self-test warning alarm has been changed to prevent settings from being
defaulted and to prevent continuous rebooting when triggered by a defective module
Products: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Impacted firmware: All to 6.02?
Corrected firmware: 5.84, 6.03
Workaround: None
Description: A defective module can trigger an “Equipment Mismatch” self-test alarm. Previous firmware
revisions have shown that, under this condition, the relay settings can be defaulted and, if an “update
order code” command is submitted, the relay can fall into continuous rebooting. This firmware release
ensures that settings are not defaulted and prevents continuous reboot when UR relays are under the
described conditions. Users having URs with a previous firmware version can detect that settings have
been defaulted when an “Equipment Mismatch” alarm and a “Relay out-of-service” alarm are active
simultaneously. A continuous rebooting condition can be detected by identifying intermittent and
consistent communication in and out events. For details on self-test warning functionality, see the
instruction manual of any applicable UR device.
