Procurve 5406Zl And 8206Zl Configurations Using The - HP ProCurve 2520 Planning And Implementation Manual

Planning and Implementation for the 5400zl/8200zl Switches
Configuration Examples
In a system with mixed power supplies, failover is calculated based on the
largest power supply failing. If it turns out to be the smaller power supply that
fails, some of the ports that were powered off during the power failure will
come back on. For example, in figure 4-5 there are mixed power supplies
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.
ProCurve 5406zl and 8206zl Configurations using the Power
Supply Shelf
The following example configurations are the same for the 5406zl and 8206zl
switches. As shown in Figures 10-7 and 10-8, the Power Supply Shelf can be
connected to the 5406zl or the 8206zl to supply extra or redundant PoE/PoE+
power to the PoE modules.
