Patton electronic 2073RC user manual Powering up your 1001R14 rack, Connecting to a DTE Device

Powering up your 1001R14 rack

The power supplies that come with your 1001R14 rack system are equipped with a power entry connector on the rear power supply card. The power supplies are hot-swappable, so you are not required to remove the cards from the rack while applying power to the system.

Note Please refer to the Model 1001R14 Series User Manual AC and DC Rack Mount Power Supplies for fuse and power card replacement information.

4.2 INSTALLING THE MODEL 2073RC INTO THE CHASSIS

The Model 2073RC 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 guide- line for installing each Model 2073RC 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.

Note Since the Model 1001R14 chassis allows “hot swapping” of cards, it is not necessary to power down the rack when you install or remove a Model 2073RC.

4.3CONNECTING TO A DTE DEVICE

The serial port on most rear interface cards are hard-wired as “DCE” (Data Communications Equipment). The interfaces are designed to plug into a DTE such as a terminal, PC or host computer. When making the connection to your DTE device, use a “straight through” cable. When pur- chasing or constructing an interface cable, refer to the pin diagrams in Appendix B on page 25 as guides.

4.4 CONNECTING TO A DCE DEVICE

The rear interface cards on most interface modules are hard wired as “DCE”. Therefore, you must use a tail circuit cable when connecting to a modem or other DCE device. When purchasing or constructing a tail circuit interface cable, use the pin diagrams in Appendix B on page 25 as a guide.
