Service-disruption hazard
A cold reset, reseat, or replacement of a card is service impacting if the card is currently
carrying services. To determine if any services are currently carried over a card, perform
the procedure “Reseating a Card” (p. 3-19).
If
there are services currently carried over the card, it may be best to wait for a
maintenance window before resetting, replacing, or reseating the card.
At the end of each step wait to see if the fault clears. If not, continue with the next step.
