environments and with different types of devices. The Powerware 9355
has two available communication bays for any X-Slot card, including:

network drops. In addition, a Powerware Environmental Monitoring
Probe can be attached to obtain humidity, temperature, smoke alarm,
and security information.

for UPS status: Utility failure, Low battery, UPS alarm/OK, or On
