Server Technology PP02 - Manual (Page 23)

Off-Hook (busy) RE BOOT Option
The one condition that can block you from initiating an immediate reboot with Remote Power On/Off is an endless
busied-out line. If the Power On/Off +Aux unit is on the same line as the host modem, as is generally intended, and the
modem refuses to hang-up, the line will remain constantly 'busy' and remote power control will be inaccessible.
In such cases, if the host modem or fax server locks-up and fails to release the line, the only condition detectable is OFF-
HOOK; it will not be possible to ring the line as the caller will simply receive the busy indicator from the local telephone
carrier. For this reason, a maximum 2 hour off-hook limit can be enabled. With this Off-Hook
RE BOOT option enabled,
ANY off-hook condition that exceeds two hours will effect an immediate RE BOOT.
Important: The off-hook limit will apply to every single continuous off-hook condition, thus limiting each call to a
maximum continuous on-line time of 2 hours.
DIP Switch Configuration - RE BOOT Mode
The following outlines the DIP-switch positions for the various functions that apply to the RE BOOT Operating Mode.
Each switch is defined as either OFF (up) or ON (down). DIP-switch changes are dynamic - selections become effective
immediately without having to power-cycle the unit.
NOTE: Similar to the Power-OFF Delay Time option in the Power-ON Mode, DIP-switches 3 and 4 may be used to set a
RE BOOT Delay. Generally, these two switches will remain OFF (up) to provide an immediate (one second delay)
reboot. If a RE BOOT Delay is desired, refer to the Power-OFF Delay Time settings on page 18 for the DIP-switch
configuration.
Selecting the RE BOOT Mode
DIP-switches 1 and 2 being placed in the up position selects the RE BOOT Mode:
1|OFF 2|OFF
