6. As previously mentioned, the board is factory configured for a Level 2,
transformer type transceiver, which means there is a jumper at location
1-2
and position 7-8. If you have a Level 1, capacitive coupled type tran-
sceiver, add a jumper across position
5~,
but do not remove either of the
other jumpers.
7. Replace the board by pushing it back into the slot. Make sure the board is
seated securely, and the retaining screws are tightened.
Examples of Levelland Level 2 transceivers are at the beginning of this section.
1. Find the Ethernet transceiver cable. It is a thick cable with IS-pin D con-
nectors at both ends, also cailed a "drop" cable. The male end of the Ether-
net cable has a pair of metal studs that
fit
into the slide lock assembly
attached to the CPU board's "ETHERNET" jack. Plug this male end into the
"ETIIERNET" jack. Push the slide lock over the studs to fasten the D con-
nector securely in place.
