SREPN Installation
Upgrade the SRP
Verify the SRP status
1. Verify that the TN2301 switch is in the AUTO position and the green AUTO
LED is on.
2. Verify that the red BKUP LED on the TN2301 is off.
3. Verify that the red SURVIVE MODE ON LED is off.
4. Verify that the yellow DATA LED is on.
5. Verify that the green LED on the EPN TN775C maintenance circuit pack is
double flashing. This indicates that EPN can go into the survive mode if
needed.
Upgrade the SRP
1. Check the link status between the G3r PPN and the associated SREPN.
The link must be up and functioning before you can upgrade. If the system
is in "survive mode," resolve the alarms and return the link to service
before proceeding with the upgrade.
2. Continue the upgrade by referring to the R9si upgrade procedures in
DEFINITY Made Easy tools.
