4.4CONNECTING THE SEHI TO THE POWER SOURCE

NOTE

The SEHI uses a universal power supply that operates between 100–125 Vac or 200–250 Vac, 50/60 Hz.

Connect the SEHI to the power source as follows:

1.Plug the power cord into the back panel of the SEHI.

2.Plug the other end of the power cord into a grounded wall outlet.

3.Verify that the PWR LED is on, indicating that the SEHI is receiving power. After the SEHI runs a self test, the CPU LED blinks green indicating normal operation. If the LED remains red, the processor is faulty, contact Cabletron Systems Technical Support.
