Installing the Series 8200zl Switch
Installation Procedures
Installing the Series 8200zl
Switch
If a redundant power source is available, it is desirable to power one
switch power supply from the regular AC source, and the other power
supply from the redundant AC source. This will provide redundancy in AC
power to the switch, as long as the switch PoE power usage falls within
the capability of one power supply. If both power supplies are plugged
into a common AC source, there is still power supply redundancy, that is,
protection against power supply failure, but if the AC source fails, the
switch will lose all power.
2. Re-check the LEDs during self test. See “LED Behavior” on page 2-21.
8. (Optional) Connect a Power Supply Shelf
to the switch
1. Connect the supplied external power supply (EPS) cables to the switch
and to the Power Supply Shelf.
2. Tighten the thumb screws on all connectors to prevent any accidental
disconnects.
3. Plug the power supply cords into the power connector and into a nearby
properly grounded AC power source.
The ProCurve Switch zl Power Supply Shelf, (J8714A), hereafter referred to
as the EPS, is an accessory product for the Series 8200zl switch. The EPS
provides External Power-over-Ethernet (PoE) power for up to two 8200zl
switch products.
The EPS can supply up to 1800 watts (depending upon which power supplies
are installed) of PoE power to the switch if the internal PoE power supply
should fail, or as additional PoE power to be made available to the switch’s
PoE ports. For further information regarding the EPS PoE capabilities, see
the ProCurve PoE (Power over Ethernet) Devices Planning and
Implementation Guide and the ProCurve Power Supply Shelf Installation
and Getting Started Guide, which are on the ProCurve Web site at
www.procurve.com/manuals. See page 5-1 for details.
The EPS is an unmanaged power supply that only provides information by
way of LEDs.
EPS Operation
The EPS has a mechanism for detecting that it is connected to a valid switch
with an EPS cable. When the EPS is connected to a powered switch it will
provide additional PoE power to the switch within 2 seconds.
