b. Reapply input power to the relay.
c. Wait 10 minutes after power-up of the relay to allow the
relay to detect any hardware changes made during the
upgrade process.
Step 3. Enter Access Level 1 using the ACC command and Access
Level 1 password.
Step 4. Enter Access Level 2 using the 2AC command and Access
Level 2 password.
Step 5. Type STA <Enter> to check the relay status and accept new
