Setting Up the Chassis

3-6 Chassis Setup

3.2.5 Installing a Power Supply

You must install at least one 7C203-1 power supply into the N3 chassis. One power supply

provides sufficient power for most module configurations, but a second power supply can be

installed to provide a redundant, load sharing power source. When two power supplies are

installed, the load is evenly distributed. If one power supply fails for any reason, the second power

supply assumes the load. The two slots labeled PS1 and PS2 at the bottom of the chassis

(Figure 3-4) are reserved for the power supplies. A large flat blade screwdriver is needed to install

the power supplies.

To install the power supply into the chassis, refer to Figure 3-4 and proceed as follows:

1. Unpack the power supply by removing it from the shipping box and sliding the two foam end

caps off the unit. (Save the shipping box and materials in the event the unit must be reshipped.)

2. Remove the power supply from its protective plastic bag. (Save the shipping box and materials

in the event the unit must be reshipped.)

3. Examine the power supply carefully, checking for damage. If any damage is noted, DO NOT

install the power supply. Contact Enterasys Networks immediately.

4. Slide the power supply into the slot labeled PS1 as follows:

a. Hold the power supply by grasping the handle located on the front panel and using the other

hand to support the power supply.

b. Holding the power supply horizontally, align the metal guides of the power supply module

with the metal guides at each side of the chassis opening, as shown in the exploded view in

Figure 3-4.

c. With the power supply properly inserted into the opening, carefully slide the power supply

forward until it is connected to the backplane. The front panel should be flush with the face

of the chassis. If significant resistance is encountered before the front panel is flush, remove

and reinsert the power supply. Do not force the power supply into place.

NOTE: If you plan to configure the chassis with only one power supply module, install it in slot

PS1. The chassis is shipped without a coverplate over slot PS1.

Caution: Forcing a misaligned power supply into place can damage the power supply and/or the

chassis backplane.

Precaución: Colocar de manera forzada una fuente de poder o no colocarla bien alineada podría

dañarla y/o maltratar el panel posterior del chasis.
