Powerware 9330 operation manual Housekeeping

·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	= UPS_Remote_Notification---Default (40 characters maximum)
<space>	= ASCII space character (0x20)
mmm	= Event message for notice or alarm (40 characters maximum)
<LF>	=	ASCII line feed character (0x0A)
<CR>	=	ASCII carriage return character (0x0D)

If calling a pager service and the service answers, the modem can delay momentarily and before dialing the pager number. Refer to “Configuring the Modem to Call a Numeric Pager” section of this chapter for more information.

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 or the front panel is reset. 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 5 minute through 60 minute time periods before reattempting the call. If answered, the UPS ceases further attempts to call. Each unsuccessful attempt to call causes an unsuccessful notify event to be logged into the UPS event log.

If all call groups are active, the UPS alternates between calling the groups. The Call Out process is terminated any time a successful connection is made by a remote terminal or by resetting the front panel of the UPS.

13.3.3 Housekeeping

When the modem is idle, the UPS “pings” (tests for connection) the modem by sending an “AT” to the modem at 15 minute intervals. If the modem does not respond correctly, by sending “0” (OK) 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, three attempts to re-initialize the modem are made. Re-initialization is then attempted every 15 minutes or until the communications mode is changed by the UPS front panel controls (or the modem is successfully re-initialized). For each unsuccessful attempt, the UPS logs a check modem event into the event log. When the modem link is confirmed, the UPS communications resume normal operation.
