9. Connecting Power to the Device
With physical installation of the switch or routing switch complete, it is now time to power up the system and
connect the network devices.
CAUTION:There is no separate on/off power switch for the device. The device is powered on when the power
cord is connected to a power supply and to a power source. To turn the system off, simply unplug the power
CAUTION:The power sockets should be installed near the device and should be easily accessible.
CAUTION: If your installation requires a different power cord than the one supplied with the device, be sure to use
a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country.
The mark is your assurance that the power cord can be used safely with the system.
NOTE: When you power on a Chassis device that requires multiple power supplies, make sure you apply power
to all the supplies (or at least the minimum number of supplies required for your configuration) at the same time.
Otherwise, the device either will not boot at all, or will boot and then repeatedly display a warning message stating
that you need to add more power supplies.
For a Chassis device, ensure that all modules and power supplies are properly inserted, and that no module
slots or power supply slots are uncovered.
WARNING: Electrical shock hazard. Never allow any part of your body to be inside the chassis when the device
is connected to a power source or to the network.
Remove the power cord from the shipping package.
Attach the AC power cord to the AC connector on the front panel of Chassis device or the rear panel of Fixed
port devices. If more than one power supply is installed, attach a power cord for each power supply.
Insert the power cord plug(s) into the appropriate outlet(s).
10. Connecting Network Devices
HP switches and routing switches can support connections to other vendors' routers, switches, and hubs as well
as to other HP switches, routing switches, and hubs.
Important! Cable Grounding Instructions
HP provides a cable-grounding kit for use with HP 9304M/HP 9308M chassis modules designed for UTP copper
networking cable connections. Use this grounding kit to help prevent ESD damage to your routing switch
components when connecting cables to the modules.
CAUTION: Before connecting Category 5 or better UTP copper networking cables to a chassis module on the HP
9304M or HP 9308M, use the CESD grounding tap (shipped with the HP 9304M and HP 9308M and with chassis
modules designed for UTP copper networking cables). See the Cable Grounding Instructions included with the
CESD grounding tap. If you did not receive a CESD grounding tap kit (HP part number 5064-9974) with the above
HP products, you can request one without charge from your HP Customer Care Center (CCC). To contact the
CCC for your area, see the support and warranty booklet (Support is as Close as the World Wide Web!) shipped
with your HP product. CCCs are also listed in the HP ProCurve Networking Service and Support Guide available
at http://www.hp.com/go/hpprocurve. (Click on Technical Support, then Support Services.)
