Replacing the Power Supply Fuse
The rack chassis power supply uses a 1.5A, 250V fuse. The fuse
compartment is located just below the AC socket on the rear card. to
replace the fuse, follow these three steps:
1.
Using a small screw driver, pop the compartment open. It will
slide open like a drawer. Depending upon the exact part used,
the drawer may slide completely out of the fuse holder or it
may stop partway out.
2.
There are two fuses in the drawer. The front fuse is the spare
and the rear fuse is the “active” fuse.
3.
If the active fuse appears to be blown, remove it from the clips
and replace it with the spare, which is located in the front
compartment. Note the size and rating of the blown fuse
before discarding.
4.
Using the part number found in Appendix C, order a new
replacement fuse* from Patton Electronics. You may also
choose to buy a replacement fuse from a nearby electronics
store.
4.2 INSTALLING THE MODEL 1065RC INTO THE CHASSIS
The Model 1065RC is comprised of a front card and a rear card.
The two cards meet inside the rack chassis and plug into each other by
way of mating 50 pin card edge connectors. Use the following steps as
a guideline for installing each Model 1065RC into the rack chassis:
1.
Slide the rear card into the back of the chassis along the
metal rails provided.
2.
Secure the rear card using the metal screws provided.
3.
Slide the card into the front of the chassis. It should meet the
rear card when it’s almost all the way into the chassis.
4.
Push the front card
gently into the card-edge receptacle of the
rear card. It should “click” into place.
5.
Secure the front card using the thumb screws.
4.3 WIRING THE MODEL 1065RC
Each of the rear interface cards compatible with the Model
1065RC has one RS-232 port and one 4-wire (twisted pair) port.
These cards provide a female DB-25 for RS-232 connection.
4.3.1 RS-232 CONNECTION
The Model 1065RC uses a DB-25 female to connect the RS-232
interface to your computing hardware. It is pinned according to the
RS-232C/V.24 interface standard. For specific interface pin-outs,
please refer to the diagrams in Appendix D of this manual.
The Model 1065RC is wired to connect to a DTE. If your RS-232
output device is a DTE, use a
straight though cable to connect to the
Model 1065RC. If your RS-232 output device is DCE, call Technical
Support at (301) 975-1007 for specific installation instructions.
NOTE:
Since the Model 1001R14P chassis allows “hot swap-
ping” of cards, it is
NOT NECESSARY TO POWER DOWN the
rack when you install or remove a Model 1065RC.
*WARNING:
For continued protection agaisnt the risk of
fire, replace only with the same type and rating of fuse.
