Displaying the Status of the Power Supplies
You can display the status of the power supplies by entering the
show chassis
command at any level of the CLI.
The display shows whether a power supply is installed in the specified power supply slot and the status of the
power supply, which can be one of the following:
•
OK – The power supply is functioning properly and supplying power to the chassis and installed modules.
•
Failed – The power supply is not functioning and is not supplying power to the chassis and installed modules.
Replacing the FSX and FSX 800 Fan Tray
The fan tray in the FSX and FSX 800 chassis contains six fans and one fan control module. If any of these
components fail, you must replace the entire fan tray.
NOTE:
The fan tray on the FSX 800 is a non-redundant, hot-swappable fan tray.
Before replacing the fan tray, you must power down the chassis and remove the power cables from the chassis
power supplies.
To replace the fan tray, you need the following:
•
A new fan tray, which you can order from Foundry
•
An ESD strap (provided with the fan tray kit) or an ESD wrist strap with a plug for connection to the ESD
connector on the FSX chassis.
•
In addition to the above, you might also need a #2 Phillips-head screwdriver.
WARNING:
For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.
To replace the fan tray, do the following:
1.
Power down the chassis and remove the power cables from the chassis power supplies.
2.
Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located in the
lower right corner of the chassis front.
OR
Use the ESD strap provided with the fan tray kit. Attach the copper tape end to a bare metal area on the
chassis.
3.
The FSX and FSX 800 ship with two extra screws installed in the right side of the chassis. These screws
secure the fan tray, protecting it from damage during shipment. These screws should have been removed
during installation. If these screws were not removed during installation, you must remove them before
replacing the fan tray. Figure 7.15 shows the location of the screws.
To perform this task, you need a #2 Phillips-head screwdriver.
