Power Supply And Fan Operability Test - Dell Force10 E300 Installing And Maintaining

Power Supply and Fan Operability Test

After you have completed the fan tray and power supply installation, verify their operability by supplying
power to the chassis and verifying the status LEDs.
NOTE: If there is an AC Power Supply or DC PEM failure, the entire unit must be replaced. There are no field
serviceable parts inside the AC Power Supply or DC PEM unit.
Before you begin this power test, inspect your equipment rack and chassis. Verify that:
• Each AC power supply or DC PEM is properly installed in the correct slots.
• Your power cables connect to an appropriate AC outlet or DC supply in a manner that complies with
your local electrical codes. For DC systems, a Main Disconnect must be provided.
• On the DC PEM(s), use a voltage meter to verify power on the cables. Also verify that the Voltage LED
is green.
• A power supply blank is installed in any empty slot.
• The fan tray is installed
WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this system
without the safety cover provided with each DC PEM.
To test the power supplies and the fan tray:
Step Task
1
With the fan tray and either AC power supplies or DC PEMs installed, power on the system.
• if AC Power Supplies are installed, flip on each switch (located on the front of the AC Power Supply) to the
ON position; or
• if DC PEMs are installed, flip the Over Current Protector (located on the PEM front panel) to the ON position.
2
In a DC PEM, the Status LED should be green.
In an AC Power Supply, the top Input AC and Output DC LEDs should be green.
If these LEDs are not lit or the Status LED is amber on a DC PEM, check that the unit is properly installed. Verify
the power source. If the LEDs remain unlit, power off all modules and replace the unit.
3 The fan tray LED should be green (online). Verify that air is flowing through the chassis.
If the fan tray is not operating properly or air is not flowing through the chassis, power off the chassis at the
remote power source. Ensure that the fan tray is properly installed. Verify the remote power source. If the fan tray
LED remains unlit, replace the fan tray.
4
After you have verified the power and fan operability, power off the chassis to continue the installation process.
• for DC PEMs, de-energize the Main Disconnect and flip the Over Current Protector to the OFF position.
• for AC Power Supplies, flip the switch to the OFF position and disconnect the power cords.
Verify that the LEDs are not lit.
