Recovering From a Power Failure

For Systems With a Backup Power Supply

If your site is equipped with a backup power supply, system memory will be preserved in the event of power failure. However, because your X.25 hardware does not have backup capability, any on-board RAM-based memory is lost.

Recovery from a power failure is automatic when the /etc/powerfail script is invoked by /etc/inittab. Otherwise SAM (or x25init) must be used to manually re-initialize the interface after a power failure.

The recovery mechanism informs the X.25 driver of the power failure.

The X.25 driver then “marks” the interface as “down” and a

DISCONNECT INDICATE is received on all open SVCs.

For Systems With No Backup Power Supply

If your system does not possess the battery backup option, both system memory and interface card memory are lost. You must reboot your system.
