9. Connect the wire to your DC power source, making sure to connect the -48V cable to the negative terminal on the power
supply and the 0V cable to the positive terminal as marked on the power supply.
The equipment installation must meet NEC/CEC code requirements. Consult local authorities for regulations.
DANGER
Make sure that the power source circuits are properly grounded, then use the power cord supplied with the device
to connect it to the power source.
NOTE
Ensure that the DC return is isolated from the chassis ground (DC-I) when connections to the power supply are made.
CAUTION
For a DC system, use a grounding wire of at least 6 American Wire Gauge (AWG). The 6 AWG wire should be
attached to an agency-approved crimp connector crimped with the proper tool. The crimp connector should allow
for securement to both ground screws on the enclosure. For the Ground lug, use UL listed Panduit crimp
connector, P/N LCD6-10A, and two 10-32, PPH, screws to secure crimp connector to chassis. Grounding
position is located on the side of the chassis adjacent ground symbol.
NOTE
To insure adequate bonding when attaching the provided Panduit LCD6-10AF two-hole ground lug, a minimum of
20 inch pounds of torque is required to be applied to the mounting hardware used to attach the ground lug. Use a star
washer to ensure an NEBS compliant connection.
Device installation
You can install devices on a desktop, or in an equipment rack.
Installing the device on a desktop
Follow the steps for desktop installation.
1. Set the device on a
at desktop, table, or shelf. Make sure that adequate ventilation is provided for the system - a 3-inch
clearance is recommended on each side.
2. Go to System power on page 56.
Installing the device in a rack
For rack mount installation, Extreme Networks recommends that you use the rack mount ears attached to the unit. Each unit ships with
rack ears attached to the front of the unit. You can mount the rack ears in 4
dierent locations on the device.
NOTE
While attaching the chassis to the rack, star washers shall be used to provide better grounding of the chassis to the rack.
Additionally if any single hole grounding lugs are used star washers shall be used as a means to prevent rotation of the lug.
Forward rack mount position
The Extreme Networks devices ship with the rack ears attached to the front of the device as shown below.
