IP Connectivity between 15252 and 15201

I have build a channel between 15252 and a 15201, with unprotected modules and clip with VLR. I have set datarate on clip as gbit_eth on the 15252 clip 23 and scu clip 23. I have connected2* 6513 with 1000LX-1300nm module to 15252 clip and 15201 clip. I can see the interface as" line up and protocol down". I have made use of MMF cable to connect to clips. I have no alarms on the MCU. Both MCU and SCU are on the same rack.

Back to Back IP connectivity with 2*6513 is working fine.

What is the possible reason for the interface showing as "line up protocol down".

Re: IP Connectivity between 15252 and 15201

The section 'Channel Installation in an ONS 15252 MCU' in the document titled 'Installation' should help. The URL is http://www.cisco.com/univercd/cc/td/doc/product/ong/15200/15200ist/200ist20/0020ist3.htm.
