3.3.4 Connecting Power to the 2E42-27R or 2E43-27R
To connect the 2E42-27R or 2E43-27R 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 CPU LED is not green after one minute and
turns yellow, 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 2E42-27R and 2E43-27R have two power supplies with
automatic voltage sensing that allows connection to power
sources ranging from 100–125 Vac or 200–250 Vac, 50/60 Hz.
NOTE
It takes approximately one minute for the 2E42-27R or
2E43-27R to boot up.
