HP Power over Ethernet (PoE/PoE+) Planning and Implementation Guide

Planning and Implementation for the HP 5400zl/8200zl Switches
Configuration Examples
offering 900 W+ 273 W for 1173 W total. Failover power will be calculated at
273 W, so if a power supply fails all the controllers will fall back to a power
level that can be supported by 273 W. If it turns out the 273 W supply failed,
the system will detect that during the power supply polling cycle and increase
power back up to 900 W total. This would result in some load coming back on
if the total power used by all the loads in the box was greater than 273 W.
HP 5406zl and HP 8206zl Configurations using the
Power Supply Shelf
The following example configurations are the same for the HP 5406zl and HP
8206zl switches. As shown in Figures 13-7 and 13-8, the Power Supply Shelf
can be connected to the HP 5406zl or the HP 8206zl to supply extra or
redundant PoE/PoE+ power to the PoE modules.
