Black Box ACS251A Manual De Usuario

• Plug any local mouse into the Local Unit’s 6-pin mini-DIN female connector

labeled with the word “Local” and a mouse icon.

Make a last pair of attachments to the connectors on the Local Unit’s rear panel:

• Attach the SC male connectors at the Local-Unit end of your duplex fiber

cabling to the Local Unit’s SC female connectors. (The Extender’s SC
connectors are keyed so that you can’t plug the fiber cable in the wrong way.)
Make sure that this fiber cabling, from here all the way to the Remote Unit, is
either 62.5/125-µm or 50/125-µm multimode type for the Extender II
(ACS250A) or is 9/125-µm single-mode type for the Extender II-SM
(ACS251A). It can either be a single cable that will run all the way to the
Remote Unit or a patch cable that will run to your fiber-distribution closet. Just
keep in mind that the more fiber connectors that the Extender’s optical signal
runs through, the more it attenuates.

• Plug the output cord of one of the Extender’s included power supplies into

the 2.1-mm barrel jack on the Local Unit’s rear panel. (The two power
supplies are identical, so you can use either one.) Attach the female end of the
power supply’s input cord to the IEC 320 male inlet on the transformer. Plug
the other end of the input cord into a working AC outlet. The Local Unit
should power up immediately—it has no ON/OFF switch. The green Status
LED on its front panel should begin flashing to show that it isn’t getting a
video signal from the CPU yet.

Don’t power up the attached devices yet—wait until you’re ready to test the

system after installing the Remote Unit and remote equipment.
