Installing the Device

3.4.3Connecting Power to the Device

NOTE

The 2H23-50R and 2H33-37R have two power supplies. The power supplies have automatic voltage sensing that allows connection to power sources ranging from 100–125 Vac, 2.0 A or 200–240 Vac, 1.0 A, 50/60 Hz.

To connect the device 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.

NOTE

It takes approximately one minute for the device to boot up.

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 CPU LED is still not green, contact the Cabletron Systems Global Call Center. Refer to Section 1.6 for details.
