AutoCross jumper

The AutoCross jumper is located on the media converter’s circuit board (labeled NA = No Autocross; A = AutoCross). See Jumper position below.

Install the slide-in-module

To install the CSRFB10xx-100 media converter slide-in-module:

1.	Locate an empty installation slot on the PointSystem™ chassis.
2.	Carefully slide the module into the slot, aligning the module with the
	installation guides.

Note: Use small needle-nose pliers to set the jumper.

AEither straight-through or crossover cable can be used for all twisted-pair copper links.

NA	Straight-through or crossover twisted-
	pair cable, depending on installed site
	converters, MUST be installed at EACH
	twisted-pair copper link.

Loopback test		Frames

The loopback test is an automatic test run from the center chassis converter with SW6 set to ‘center,’ the UP position of the switch; and on the terminal converter with SW6 set to ‘terminal,’ the DOWN position of the switch.

Note: This test is self-running after being initiated through software on the center converter.

The Loopback test does the following:

1.The center converter will put the terminal converter in loopback mode.

2.The center converter sends 100 packets to the terminal converter.

3.The center converter will monitor its receiver for:

a.good packets

b.CRC errors

c.timeouts

4.After the center converter receives all 100 packets back or a time out occurs, it will update its counters and return the terminal converter to its previous mode of operation.

After completing the test, normal operation of the center and terminal converters is established automatically.
