3.4.3 Connecting Power to the Device
To connect the device to the power sources, proceed as follows:
1. Plug each power cord into a grounded wall outlet, see Figure 3-5. To
take advantage of the load sharing and redundancy capabilities, each
power cord must be plugged into a dedicated ac outlet. The POWER
LED turns on (green) and the CPU LED turns on (green) briefly.

2. Observe the LANVIEW LEDs. After a successful boot, the CPU LED
turns on (green). If the PWR LED is not green after one minute and
turns amber, there is no power redundancy. Check the power cord
connections and the power source. If there are no problems with the
power cord connections or power source and the CPU LED is still not
green, contact the Cabletron Systems Global Call Center. Refer to
Section 1.6 for details.
NOTE
The 2H23-50R and 2H33-37R have two power supplies. The
power supplies have automatic voltage sensing that allows
connection to power sources ranging from 100–125 Vac, 2.0 A
or 200–240 Vac, 1.0 A, 50/60 Hz.
NOTE
It takes approximately one minute for the device to boot up.
