Are you pulling the PAM only, or the whole CAM?

What IOS release are you on?  This is an LS1010, I assume.  ASP-B or ASP-C (or 
8515MSRP)?

Those boxes are quite old, now, and you may be tickling an old hardware or IOS 
bug.  If you have support on it, it's EOL Last Date of Support isn't until 
April 29, 2011.  Can't get a new contract now, but you can renew an existing 
one until April 2010.

I had an 8510MSR 'section' in an old Catalyst 5500 I retired a few months ago, 
and never had issues with OIR on IOS 12.1(26)E3 (itself a pretty old, but 
still supported, IOS train).  I only used OC3 and OC12 PAMs in it, so you 
might be tickling a bug in your particular PAM.

There is a 12.0 mainline caveat for the LS1010, CSCdw36579, that relates to 
this issue.  The description is:

Symptom: OIR of port adapters does not work as expected using 12.0 mainline 
software on the LightStream 1010.

Workaround: Use the latest W5 image or do not OIR the port adapters 
individually. OIR the carrier module, remove the port adapter and then 
reinstall the carrier module.

So you want to be on the latest 12.0W5 train image, or upgrade to the 12.1E 
train.
