The LSR_FORCE_OPEN Alarm Is Not Reported Before Logical Ports Are Deleted

Publication Date:  2012-07-25 Views:  105 Downloads:  0

Issue Description

If you delete a port when the laser of the port is enabled, the board does not report the LSR_FORCE_OPEN alarm. 

Alarm Information


Handling Process

Check whether the laser is enabled before deleting the logical port. If the laser is enabled, disable the laser before deleting the logical port to avoid eye damage. 

Root Cause

If the logical port is deleted, that is, the logical port no longer exists, it is abnormal if the LSR_FORCE_OPEN alarm is still reported. Therefore, when you delete the logical port, the board receives the deletion information and then stops the LSR_FORCE_OPEN alarm according to the deletion information.
