Fan Tray Assembly
The Fan Tray Assembly provides air flow and cooling to the switch fabric and slot controller
modules located in the front of the unit. If a fan fails a RED LED will illuminate on the Fan Tray.
In the event of a fan failure, replace the entire Fan Tray assembly with a spare Fan Tray kit (GDC
P/N 010K389-001).
Fan Tray Installation
1. To install the Fan Tray Assembly, slide the Fan Tray along the track and push firmly until it
engages the connector in the unit.
2. Using a flat-blade screwdriver, tighten the (2) captive screws on the front panel.
3. To remove the Fan Tray Assembly, loosen the (2) captive screws on the front panel and slide
the Fan Tray out of the unit.
Note
The customer must replace the entire Fan Tray Assembly. Individual fans on the assembly can only be
replaced by a qualified service engineer.
Power Supplies
When the Xedge 6280 chassis is configured for power supply redundancy, the Xedge 6280 remains
powered under the following conditions:
•
one power feed fails
•
one power supply fails
To power a half-loaded chassis and provide power redundancy, the chassis requires a minimum of
two power supplies. A half-loaded chassis has a maximum power rating of 45A at +5Vdc. The
minimum power supply configuration requires one power supply installed in the A Main power
supply slot, and a second in the B Main power supply slot.
To power a fully-loaded chassis and provide full power supply redundancy, the chassis requires four
power supplies (one in each power supply slot). A fully loaded chassis has a maximum power rating
of 90A at +5Vdc.
In addition to providing power supply redundancy, the chassis also protects the switch from
catastrophic short circuits in the power supply itself by incorporating blocking diodes on all power
supply outputs.
Power Supply Precautions
WARNING
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.
Note
IMPORTANT! Although the Xedge 6280 chassis power supplies are available in AC or DC versions, the
National Electric Code (NEC) does not allow installation of an AC and DC power supply in the same chassis.
Special keying is provided in the chassis which prevents installing either power supply in the wrong chassis.
Note
Each power supply requires a minimum load of 3A or one slot controller, switch fabric, or LIM. When using
a dual power supply configuration, the power supplies should be located in the Main A and Main B slots.
