Connect The Power Supply Shelf To A Switch; Connecting Eps Ports To Switches - ProCurve zl Series Installation And Getting Started Manual

4. Connect the Power Supply Shelf to a Switch

Connect the EPS cables from the supported network switches to the appro-
priate ports on the Power Supply Shelf. Also see "Recommended Connection
Topologies" on

Connecting EPS Ports to Switches

To connect:
Push the EPS cable plug into the desired
port until the thumb screws engage with
the screw holes in the unit. Tighten the
thumb screws.
Always attach the EPS cable to the
connector that is associated with an
installed power supply. For example, if
there is a power supply installed in slot 1,
connect the EPS cable to EPS 1.
When power is on for the Power Supply
Shelf and for the connected switch, the
Device Connected LED should go on to
confirm a powered-on switch is at the
other end of the cable.
If the Device Connected LED does not go
on when the cable is connected to the port, see Diagnosing with the LEDs in
chapter 3, "Troubleshooting."
To disconnect:
Unscrew the thumb screws on the plug and pull the plug out of the port.
C a u t i o n
Disconnecting the EPS (PoE power) cable with power flowing is not
supported, and could cause loss of PoE power to all network devices
connected to the switch. The Power Supply Shelf must be powered down
before disconnecting the EPS (PoE power) cable, if power is flowing. Only
the power supply to be disconnected must be powered down. The EPS cable
may be connected at any time.

Refer to
power usage, and to
available PoE power.
