Step 18. Press the ENT pushbutton.
The relay restarts and the ENABLED light turns on to indicate the
card was installed correctly.
After reconfiguration, the relay updates the part number, except
for the following indicated digits. These digits remain
unchanged, i.e., these digits retain the same character as before
the reconfiguration. Also, a communications card installed in
Slot C is reflected as an empty slot in the part number. A
regular 4 DI/4 DO card and a hybrid 4 DI/4 DO card have the
same device ID. When interchanging these two cards, the part
number for the respective slots should be updated manually.
Use the Status command to view the part number.
Use the PARTNO command from the 2AC level to enter the
exact part number of the relay.
Step 19. Update the side-panel drawing with the drawing sticker
provided in the card kit. If necessary, replace the rear panel
with the one applicable for the card and attach the terminal-
marking label provided with the card to the rear-panel cover.
Step 20. Reconnect all of the connection plugs and add any additional
wiring/connectors required by the new card.
Slot B CPU Card Replacement
When replacing the Slot B card, be aware of the following issues.
1. The new card will ship with the latest firmware from the
factory.
2. The firmware revision history should be reviewed for the
changes that were made; note that new settings added, if any,
might affect existing settings in the relay or its application.
3. If the IEC 61850 protocol option was used previously, verify
that the IEC 61850 protocol is still operational after the
replacement. If not, reenable it. Refer to Relays With IEC
61850 Option in Appendix B: Firmware Upgrade Instructions,
for the verification process.
4. Save all the settings and event reports before replacing the card.
