Installation & Setup Guide
Fan Tray Assembly
The fan tray assembly at the top of the chassis draws air from the bottom of the chassis. The tray is
a single assembly unit and is hot-swappable for easy installation and maintenance. Each fan in the
tray provides approximately 100 cubic feet per minute (CFM) ventilation. Adequate airflow is
required through the system to ensure that the Xedge switch does not overheat.
It is recommended that at least 5.25 inches of clearance be provided above and below the chassis
when it is installed in a 19-inch or 23-inch cabinet. In addition, the temperature of air flowing into
the system should not be greater than 50 deg C.
Fan Tray Remova
l
1. Loosen the screws that affix the fan tray to the chassis.
2. Slide the module out of the shelf approximately 1 inch.
3. Wait approximately 15 seconds for the fan blades to stop rotating to avoid injury.
4. Slide the module from the shelf completely.
Xedge 6640/6645 Power Supplies
Both chassis are equipped with four slots (slots A, B, C, and D) for the installation of four power
supplies. Each pair of power supplies (A-B and C-D has an independent power feed. The
installation procedure is the same for both chassis, except where noted.
•
The Xedge 6640 chassis employs GPS-14 AC power supplies. For U.S. installations, each feed
requires 20A at 110VAC. For non-US installations, each feed requires 10A at 220VAC service.
Each GPS-14 AC power supply requires a minimum load of 3A or one slot controller, switch
fabric, or LIM.
•
The Xedge 6645 chassis employs DSP-14 DC power supplies. Each feed requires a 35 A
service.
Installation Procedure
To install a new power supply, perform the following steps:
1. Turn off the POWER switch of the power supply you are installing.
2. Select the slot you wish to use for the installation of the power supply.
3. Remove the blank panel that covers the slot by loosening its four retaining screws.
4. Carefully insert the power supply into the tracks of the slot.
5. Slide the power supply into the slot until its front panel bottoms out on the chassis (to seat the
power supply properly requires approximately 35 pounds of force).
WARNING
Use caution when removing a fan try from a chassis. Avoid the rotating fan blades by
following the procedure below.
WARNING
Use care when installing and replacing power supplies because hazardous voltages
may be present, creating an imminently hazardous situation which, if not avoided, could result in death
or serious injury. To comply with safety requirements, you must install a blank panel to cover each un-
used power supply slot.
