Verify the SRP status
1. Verify that the TN2301 switc h is in the AUTO p osition and  the g reen 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 g reen LED on the EPN TN775C maintenanc e c irc uit p ac k is 
d oub le flashing . This ind ic ates that EPN c an g o into the survive mode if 
needed.
Upgrade the SRP
1. Chec k the link status b etween the G3r PPN and  the assoc iated  SREPN. 
The link must b e up  and  func tioning  before you c an up g rad e. If the system 
is in survive mod e, resolve the alarms and  return the link to servic e 
b efore p roc eeding  with the up g rade. 
2. Continue the upgrade by referring to

SREPN Maintenance
Before starting to troubleshoot
NOTE:
When the SRP is in Normal mod e, the Expansion Interfac e c irc uit p ac k’s 
yellow LED flashes (see Tab le 2-6
). This is normal. The links to its 
c ounterpart in the R7r 
are d own and  are not re-estab lished  until the SRP 
g oes into Survive mod e.
Similarly, after normal servic e is returned  to the SREPN, the SRP is in an 
alarmed  state. This is normal for the SRP and ind ic ates that the TN2301 has 
disconnected from the SREPN, and the SRP is no longer in control.
