3.3.3 Connecting Power
To connect the 2E253-49R 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 2E253-49R to boot
up.
NOTE
The two power supplies in the 2E253-49R 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.
