Jumpers
OUT201, OUT202, etc. A 5U chassis has a 200-addresses slot and a
300-addresses slot. A 6U chassis has a 200-addresses slot, a 300-addresses
slot, and a 400-addresses slot.
The drawout tray on which each I/O board is mounted is keyed. See Installing
Optional I/O Interface Boards for information on the key positions for the
200-addresses slot trays, 300-addresses slot trays, and 400-addresses slot
trays.
Changing I/O Interface Board Jumpers
Change the I/O interface board jumpers only when you move the slot position
of an I/O board. You must remove the I/O interface boards to access the
jumpers. Perform the following steps to change jumpers on an I/O interface
board:
Step 1. Follow your company standard to remove the relay from
service.
Step 2. Disconnect power from the relay.
Step 3. Retain the GND connection, if possible, and ground the
equipment to an ESD mat.
Step 4. Remove the communications cable connected to the front-panel
serial port, if applicable.
Step 5. Loosen the four front-panel screws (they remain attached to the
front panel), and remove the relay front panel.
Step 6. Remove the 34-pin ribbon cable from the front panel by
pushing the extraction ears away from the connector.
Step 7. Disconnect the power, the interface board, and the analog input
board cables from the main board.
Step 8. Pull out the drawout assembly containing the I/O interface
board.
Step 9. Locate the jumper you want to change.
The I/O interface board jumpers are located near the front of
each I/O board, and near the interface board connector, as
shown for each type of interface board in
Figure 2.17–Figure 2.20.
Step 10. Install or remove the jumper as needed (see Table 2.6 for
jumper position descriptions).
Step 11. Reinstall the interface board, and reconnect the power, the
interface board, and the analog input board cables.
Step 12. Reconnect the cable removed in Step 6 and reinstall the relay
front-panel cover.
