Connecting Power to the Device

The 2H28-08R has two power supplies that have automatic
NOTE
voltage sensing, allowing connection to power sources ranging
from 100–125 Vac, 2.0 A to 200–240 Vac, 1.0 A, 50/60 Hz.
To connect the 2H28-08R to the power sources, proceed as follows:
1. Plug both power cords into a separate grounded wall outlet. 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.
It takes approximately one minute for the 2H28-08R to boot up.
NOTE
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 PWR LED is still not
green, contact the Cabletron Systems Global Call Center. Refer to
