Black Box ME758C-RJ45, ME759C-RJ45, May-95 Installing the Multi-Function LD Card in the MicroRack

MULTI-FUNCTION LD CARD

4.2.3SWITCHING THE POWER SUPPLY BETWEEN 120 AND 240 VOLTS

Although the MicroRack is shipped from the factory with a customer-specified power-supply configuration, you may change the configuration yourself. Follow these steps to switch the configuration of the power supply between

120 VAC and 240 VAC:

1.Making sure the rack is turned off and unplugged, remove the power supply’s front module and locate the two-position switch (labeled either “110/220” or “115/230”) near the back of the card. Slide the switch to the setting corresponding to your desired voltage.

2.Replace the existing fuses with fuses of the correct type (see step 4 of Section 4.2.2).

3.If necessary, replace the power-supply cord with a country-specific cord. (For certain countries, your supplier might be able to give you a special quote on country-specific cords.) Plug the cord back in.

4.3Installing the Multi-Function LD Card in the MicroRack

The Multi-Function LD Card is made up of a main (front) module and an interface (rear) module. The two cards meet inside the rack chassis; their mating 50-pin card-edge connectors plug into each other. Use these steps to install each Multi-Function LD Card into a MicroRack:

1.Slide the rear module into the back of the MicroRack on the metal rails.

2.Secure the rear module using the included metal screws.

3.Slide the front module into the front of the chassis. It should meet the rear module when it is almost completely in the chassis.

4.Push the front module gently into the card-edge receptacle of the rear module. It should “click” into place.

5.Secure the front module using the thumbscrews.

NOTE

Since the MicroRacks allow “hot swapping” of cards, it is not necessary to power down the rack when you install or remove a Multi-Function LD Card.
