Solution

DISPATCH INSTRUCTIONS
   WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?: Field Engineer/Administrator will want to be familiar with Qlogic switches.
   TIME ESTIMATE: 5 minutes
   TASK COMPLEXITY: 1

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
PROBLEM OVERVIEW: A fan has failed or is suspected faulty and needs replacement.
WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:

You can remove or install one of the Fan blades while the switch is operating
without disrupting service. The Fan blades are also interchangeable; that is, a Fan
blade will fit in any bay. Fan blades can have front-to-back or back-to-front air
flow; however both Fan blades and Power Supply blades must have the same air
flow direction.

***WARNING!!***
Voltage is present in an open bay when the switch is operating. To avoid
personal injury, do not place hands or objects into an open bay.

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:

***CAUTION!***
Always use an ESD wrist strap when removing and installing a Fan blade.
Keep the Fan blade in an ESD protective container or anti-static bag when
not in use.
Replacement Fan blades must be compatible with the air flow direction of
the other Fan blade and Power Supply blades. Installing a Fan blade with an
opposing air flow direction could lead to overheating.
To avoid overheating, do not operate the switch with an empty Fan blade
slot any longer than it takes to install a new Fan blade.

Removing a Fan Blade

To remove a Fan blade, rotate the latch to the full open position. Pull the Fan
blade by the latch to disengage the blade from the midplane connector. Carefully slide the Fan blade from the chassis.

Installing a Fan Blade

To install a Fan blade, do the following:
1. Open the Fan blade latch and slide the blade into the chassis until it contacts
the midplane connector.
2. Rotate the latch right-to-left to lock the Fan blade in place.
3. Observe that the Fan blade Power LED is illuminated.
4. Confirm the Fan blade status. Open a Telnet session and enter the Show
Chassis command to display the operational status of the Fan blade

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?: Confirm the Power Supply blade status. Open a Telnet session and enter the Show Chassis command to display the operational status of the Fan blade.

PARTS NOTE: P/N 373-0219 is suppose to be a back-to-front fan assembly FRU for the Qlogic 9XXX director-class switches sold by Sun. Since Sun never sold the front-to-back 9XXX units, we don't have a spare fan assembly for that configuration. Qlogic offered the 9XXX products in either front-to-back or back-to-front configurations. Since Sun cabinets were designed to accommodate back-to-front airflow, that is the only configuration we offered.
