Revised October 14, 1997
Products Affected
All AUSM-8 cards.
Problem Description
An AUSM-8 card may "hang" and not pass data.
Workaround/Solution
The AUSM-8 has a jumper labeled "W1" which should be removed. Several manufacturing runs of these cards were shipped with W1 installed, which disables a Watchdog Timer. With W1 removed the Watchdog Timer is enabled, and the "hung" card will reset itself and restore traffic continuity without external intervention. "Hung" cards with W1 still installed can be restored to operation by resetting the card.
RCN Number
Not Available.
Bug Details
Not Applicable.
Additional Information
It is recommended that a maintenance window be set for the removal of W1 from the AUSM-8 cards unless the AUSM-8 is displaying signs of being "hung," such as not passing traffic. No other action is needed.
