Power supplies—The SA6500 ships with one AC power supply installed in the back

of the chassis. You can add an optional second power supply to support redundancy

and load-sharing features. In addition, if you need to replace one of the power supplies,

you can “swap” the faulty power supply for a replacement while the optional second

power supply assumes responsibility for the entire power load, thus avoiding a situation

where you have to power off the Secure Access Service before replacing the removable

unit.

•

Cooling fans—The SA6500 ships with two cooling fans installed in the back of the

chassis. If you need to replace one of the cooling fans, you can “swap” the faulty fan

for a replacement during operation in a matter of moments. You can purchase additional

cooling fans from your vendor when you order your SA6500, or you can purchase them

in the future to replace faulty or failed cooling fans, as necessary, in the future.
