If one end of a HubSTACK Interconnect cable is disconnected without
disconnecting the other end attached to the hub, disconnect the cable from
the OUT port as shown in Figure 4-7 to ensure that the HubSTACK
Interconnect cable is terminated properly.

Proceed to Section 4.4 to connect power.
4.4 CONNECTING THE SEHI TO THE POWER SOURCE
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.
NOTE
The SEHI uses a universal power supply that operates
between 100–125 Vac or 200–250 Vac, 50/60 Hz.
