Recommended Connection Topologies
This section shows some recommended connection topologies using the
Power Supply Shelf. The Power Supply Shelf provides only EPS (PoE) power
for up to two ProCurve switches. In the illustration below, one Power Supply
Shelf with two power supplies is connected to a ProCurve Series zl Switch,
also with two power supplies. The switch provides PoE power to Ethernet
devices connected to their ports.

Status Indication
The Power Status LEDs on the Power Supply Shelf indicate if a port can
provide power. For example, if two switches are connected to the Power
Supply Shelf and the power to the switch on port 2 fails, the Power Status LED
for port 2 turns on. The Power Status LED for port 1 remains off.
