3.3.3 Connecting Power
To connect the 2H252-25R 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 separate dedicated
ac outlet. The Power (PWR) LED turns ON (green) and the CPU LED alternates between green
and amber during boot up. It takes approximately one minute for the 2H252-25R to boot up.

2. Observe the LANVIEW LEDs. After a successful boot, the PWR LED turns ON (green). If the
PWR LED is 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 amber, contact Enterasys Networks for help. Refer to
Section 1.2 for details.
NOTE: The two power supplies in the 2H252-25R have automatic voltage sensing that
allows connection to power sources ranging from 100–125 Vac, 2.5 A or 200–240 Vac,
1.25 A, 50/60 Hz.
NOTE: If the power-up sequence is interrupted on this device, or if optional hardware
has been installed or removed, this device may run an extended diagnostics sequence
that may take up to five minutes to complete.
