Planning and
Implementation for the
3500yl Switches
The table in this example configuration contains entries that show the PoE+
power available for the 3500yl-24G-PoE+.
Figure 9-6. Example of a 3500yl-24G-PoE+ Switch connecting to a HP ProCurve
630 External and/or Redundant Power Supply (J9443A)
The same considerations apply for the mini-GBIC ports as in the previous
example.
One 3500yl-24G-PoE+ switch can be supported by one 630 RPS/EPS. This is a
full redundant configuration. The switch can be supplied with power should
either part of the internal power supply fail. The 630 RPS/EPS can supply
system power to keep the switch powered on and PoE+ power to supply the
attached PoE+ devices with power.
