Removing a power supply
You can hot swap power supplies while the switch is operational.
Procedure
1. Disconnect the power cord from the power supply.
2. Lift up the power supply handle so you can grasp it.
3. Push the spring latch to the left and use the power supply handle to pull the power supply
out of the chassis.
4. If you are replacing the power supply, see Installing an AC power supply on page 24 or
Installing a DC power supply on page 29. If not, re-install the filler panel.
Installing a fan module
The VSP 7200 Series comes with three 12–V fan modules for either front-to-back or back-to-front air
flow switch cooling.
Important:
Make sure the air flow direction of your power supplies matches the same direction for your fan
modules.
Refer to the following part numbers to ensure that you install the correct fan modules in your
switch. Both the VSP 7254XSQ (fiber switch) and the VSP 7254XTQ (copper switch) use the
same fan module models:
• EC7200BTF-E6 — 12 V BACK2FRONT SPARE FAN MODULES (INC 3 FAN MODULE
KITS)
• EC7200FTB-E6 — 12 V FRONT2BACK SPARE FAN MODULES (INC 3 FAN MODULE
KITS)
There are sensors inside the chassis that monitor the temperature. These sensors send information
to a controller that automatically regulates the fan speed to maintain the proper temperature. If any
sensor exceeds its threshold, an alarm is sent. When the temperature cools by 2° below the
threshold, the alarm clears.
Use this procedure if a fan fails and you have to replace it.
Important:
All three fan modules must be installed at all times to ensure proper ventilation. If a fan fails,
replace it as soon as you can but leave it in place until you do. Leaving a fan bay unpopulated
impairs the ability of the remaining fans to cool the chassis.
