PRE5 / SCH1 - SPA problem

Hi all ,


I have ubr10k with IOS SCH1 , and PRE5 installed .


In chassis is SIP-600 with 3G SPA in bay 1/0 and all 3 port are connected to rfgw and working fine  as 1GE .


second 3G SPA in bay 1/1 is not working . connected port gi 1/1/2 to same rfgw ( 4th port ) as first SPA , and communication between gi 1/1/2 and 4th port in rfgw is not working .

on gi 1/1/2 is configured ip ,and also on 4th port of rfgw is configured ip but cant ping rfgw from cmts  . ( from all 3 port on SPA bay 1/0 i can ping ) 

output from cmts :


Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

Changing SFP on cmts and rfgw didint help .

Does on CMTS with standby

Does on CMTS with standby PRE5 , 10GE port  on standby PRE5 can work independent from activ PRE5 10GE port ?
