Routine Maintenance
On a regular basis, inspect your 8265 to verify that:
Ÿ
All blank 8265 faceplates are securely attached to the chassis.
Ÿ
At least two fans are running.
Attention: If only two fans are operational, system operation is not affected. However, you should
schedule the defective fan for prompt replacement. If fewer than two fans are operational, power off
the 8265 immediately. Do not attempt to power on again until at least two operational fans have been
installed. You should normally run the 8265 with a full complement of three fans.
Ÿ
Ventilation to the 8265 is unobstructed.
Ÿ
CPSW module, Controller module (if installed), and media module LEDs are functioning normally and
show normal readings.
Ÿ
All modules are securely seated in the backplane and firmly attached to the chassis.
Ÿ
Power requirements for all installed modules are met by the power supplies.
Ÿ
Power cords from each power supply are not frayed or damaged.
Ÿ
Cables running from each installed module are in good condition.
Ÿ
If rack mounted, the 8265 and the cable tray are securely attached to your rack.
