Hi, Please see this:
View Bulletin PSN-2006-09-029 Title Unrecognized Power Entry Module (PEM) alarm on M7i and M10i Products Affected All M7i and M10i routing platforms running JUNOS version 8.0 or lower. Platforms Affected JUNOS 8.x M-series Revision Number 1 Issue Date 2006-11-01 PSN Issue : When installing JUNOS version 8.1R1 on an M7i or M10i router, an unrecognized PEM alarm might be raised. Alarm time Class Description 2006-07-29 23:25:29 HKT Major PEM 1 Unrecognized for the platform 2006-07-29 23:25:28 HKT Major PEM 0 Unrecognized for the platform The problem is caused by an incorrect configuration on the PEM Assembly ID. These alarms can be ignored; there is no functional impact to the router. Solution: After the software has been upgraded to 8.1R2 or higher, the PEM Assembly ID is automatically updated to the correct value. No user intervention is required. Solution Implementation: Customers are encouraged to upgrade to JUNOS Release 8.1R2 or higher (when available) in order to avoid these error messages.
