Housekeeping - Powerware 9315 Operation Manual

·
The UPS logs a successful notify to the event log when the remote computer or
modem answers and leaves an event message with the following format.
nnn<space>mmm<LF><CR> where:
nnn
<space> = ASCII space character (0x20)
mmm
<LF>
<CR>
If calling a pager service and the service answers, the UPS delays momentarily and
then dials the pager number. Refer to the "Configuring the Modem to Call a
Numeric Pager" section of this chapter for more information on configuring a
modem to dial a pager.
NOTE: Because the pager service is not a modem, the UPS does not know if its
message got through; therefore, the UPS continues to call the pager service
for a programmed number of times or until a call-in reset is performed.
An unsuccessful notify event is logged into the UPS event log for each
attempted call out.
If the phone number that the UPS is calling does not answer, the UPS delays for a
time period (programmable from 1 to 60 minutes) and then reattempts the call. If
answered, the UPS ceases further attempts to call. Each call group can be
programmed for a separate number of attempts to call and delay between calls.
Each unsuccessful attempt to call causes an unsuccessful notify event to be
logged into the UPS event log.
If both call groups are active, the UPS alternates between calling the groups. The
Call Out process can be terminated at any time by calling into the UPS and
sending the reset command (press and hold [CTRL] and press [R]) or by turning
the key switch on the front of the UPS.

Housekeeping

When the modem is idle, the UPS "pings" (tests for connection) the modem by
sending an "AT" to the modem at five-minute intervals. If the modem does not
respond correctly, by sending either "OK" or "0" to the UPS, the UPS attempts to
re-initialize the modem. After a successful re-initialization, the UPS returns to the
Housekeeping function. If the re-initialization is unsuccessful, two more attempts to
re-initialize the modem are made before the UPS disables all Call Out attempts.
Re-initialization is then attempted every ten minutes or until the communications
mode is changed by the UPS front panel controls (or the modem re-initializes). For
each unsuccessful attempt, the UPS logs a modem failure event into the event log.
When the modem link is confirmed, the UPS communications resume normal
operation and Call Out is enabled.
