Backup Relay Settings
The relay preserves settings and passwords during the firmware upgrade
process. However, interruption of relay power during the upgrade process can
cause the relay to lose settings. Make a copy of the original relay settings in
case you need to reenter the settings. Use either the SEL-5010 Relay Assistant
software or
ACSELERATOR QuickSet to record the existing relay settings and
proceed to D. Start SEL
BOOT. Otherwise, perform the following steps:
Step 1. From the Transfer menu in HyperTerminal, select Capture
Text.
Step 2. Enter a directory and filename for a text file where you will
record the existing relay settings.
NOTE: If the relay does not prompt
you for Access Level 1 and Access
Level 2 passwords, check whether the
relay has a password jumper in place.
With this jumper in place, the relay is
unprotected from unauthorized
access (see the relay instruction
manual).
