Power priority mechanism
The priority mechanism is implemented in order to handle cases where the power requested by
the PDs exceeds the switch PoE capacity. This priority mechanism determines the order in
which ports will be powered on after boot, and powered off if the power resources of the module
are exhausted. Three user-configurable port power priority levels are available: low, high &
critical. Within each priority level the lower the port number, the higher the priority (by default all
the ports have low priority).
Disconnected power will be automatically reconnected to the PDs based on their priority,
whenever there is an available power budget. Immediately after the PoE has booted up, it starts
to supply power to the ports where a load is detected. Ports are powered up one after another,
based on the port priority, until the limit is reached. Power calculation is based on the actual
power consumption of the PD. After this, no more ports are powered up until the total power
consumption drops lower than the limit. The limit is 18 Watts below the maximum PoE capacity.
The remaining 18W are reserve power for a change in the power draw of PDs.
C360 converged stackable switches
The Avaya C360 converged stackable switch series is a line of stackable, multilayer switches
that provide high availability, quality of service (QoS), and Power over Ethernet (PoE) to
enhance converged network infrastructure operations. With a range of PoE and non-PoE
configurations, the C360 series is a powerful, yet cost-effective option for enterprise
applications. The C360 series offers a migration path for the P330 series, and can be stacked
with P330 switches and G700 Media Gateways.
The Avaya C360 series of converged stackable switches includes:
● A range of modules with 24 or 48 10/100 Mbps ports supporting PoE or non PoE and two
GBIC SFP slots for Gigabit Ethernet connections
● A Layer 3 capability
The available C360 switch models are as follows:
● C363T converged stackable switch
This switch has 24 10/100 Mbps ports and two GBIC SFP ports.
