Power Consumption
Several factors influence the power consumption at any given time, including the level of
network traffic and whether a powered peripheral device is connected to the LAN or
Management port of the Tropos 7320 router. Temperature can also influence the power
consumption for units configured with battery backup, due to the internal freeze protection
capability associated with the internal battery module.
AC Power Consumption
Figure 27 shows the basic relationship between throughput and AC power consumption at
normal temperatures.

AC Power Consumption with Battery Backup
When the router is equipped with a battery and the router is exposed to cold temperatures (below
-12 degrees C), the internal heater associated with the battery is activated. This causes the router
to draw additional AC power, as shown in
Figure 28 .
