Chapter 2 Installing the Cisco MDS 9500 Series
Removing and Installing Fan Modules
Step 1 Ensure that the system (earth) ground connection has been made. See the “System Grounding” section
on page 2-17.
Step 2 If a filler panel is installed, remove it from the power supply bay by loosening the captive screws and
pulling the filler panel out of the bay.
Step 3 Grasp both power supply handles and slide the power supply into the power supply bay, ensuring that
the power supply is fully seated in the bay.
Step 4 Tighten the captive screws on the power supply to 8 in-lb.
Step 5 Provide power to the PEM as described in the “Connecting the Power Supplies” section on page 2-28.
Caution In a system with dual power supplies, connect each power supply to a separate power source.
In case of a power source failure, the second source will most likely still be available.
Step 6 Verify power supply operation by checking that the power supply LEDs are in the following states:
• INPUT OK LED is green.
• FAN OK LED is green.
• OUTPUT FAIL LED is off.
Removing and Installing Fan Modules
The fan module is designed to be removed and replaced while the system is operating without presenting
an electrical hazard or damage to the system, provided the replacement is performed promptly.
The Cisco MDS 9513 fan module has 15 fans with an abrupt stop-to-fan rotation safety feature after
power is disconnected or the fan tray is removed from the midplane. The Cisco MDS 9506 fan module
has six fans and the Cisco MDS 9509 fan module has nine fans. The removal procedures differ slightly
while the installation procedures are the same for all types of fan modules.
You need a flat-blade or number 2 Phillips screwdriver to perform these procedures.
Note Because the fan modules are located on the left side of the Cisco MDS 9500 Series, Cisco recommends
guiding the cables for the system out of the right side of the chassis.
