3.3.3 Connecting Power to the 2E4X-27R To connect the 2E4X-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
turning 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 1.5 for details.
NOTE The 2E4X-27R has 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 2E4X-27R to boot up.
