IBM System Storage EXP2512 Express Storage Enclosure, Installation, User'S, And Maintenance Manual

Page: 34 / 72

Note: There is no power-on switch on the EXP2500 or on the power
supplies. A power supply is active when a power cord is connected to it and
to a power source.
The EXP2500 might take a few seconds to power-on. During this time, you might
see the EXP2500 amber fault LED, green power LED, power supply LEDs, and
blue system locator LED turn on and off intermittently. When the power-on
sequence is completed, only the green power LEDs on the front and rear should
remain lit. If one or more amber fault LEDs remain lit, see Chapter 5, “Solving
problems,” on page 41.
Powering off the EXP2500
Attention: Except in an emergency situation, never power-off if any fault LEDs
are lit on the EXP2500. Correct the fault before you attempt to power-off the
enclosure, using the correct troubleshooting or servicing procedure. For more
information, see Chapter 5, “Solving problems,” on page 41.
DANGER
Multiple power cords. The product might be equipped with multiple power
cords. To remove all hazardous voltages, disconnect all power cords.
