Appendix 2: Card Dip Switches for BHX and
Fiber Configurations
There are dip switches on the circuit board of the card itself. With these dip switches you can change
the power voltages that is put on the backpanel. By default the switches are set to off, putting no power
on the backpanel. The picture below displays where the switch is positioned on the card.
When using a ‘normal’ BPH17 (passive) backpanel with this card, the dip switch on the card
itself must be switched
OFF .
Using BPH17 with Fiber I/O
When using a BPH17 backpanel with fiber I/O, you must first set the top-side dip switch on the synapse
board to
ON . This will pass 30 volt to the backpanel. If this is not done, the relays won’t work at all.
Using BHX17b
When using the backpanel with a bypass relay (BHX17b), you must first set the bottom-side dip switch
on the card to
ON . This will pass 5 volts to the backpanel. If this is not done, the relays won’t work at all.
On the BHX17b itself, there are also 2 dip switches (see picture below). The bottom dip switch is not
connected. With the top switch you can choose the Bypass function. There are 2 possible function
indications “on” (printed on the dip switch itself) and “off”:
