[internal transformer]).

If you connect a more distant computer or
terminal to this RS-232 serial port, you’ll be able
to send switching commands to the ServSwitch
Ultra from a secondary location. You would also
connect a computer to this port to upgrade the
Switch’s firmware. Refer to Section 4.4.
RJ-12 FRS-232
Connect the shared monitor, keyboard, and
mouse to this port using an “MKM Adapter
Cable.” At the ServSwitch Ultra end, this cable
has a DB25 male connector; at the other ends,
it has appropriate connectors to plug into your
monitor, keyboard, and mouse cables. Only one
MKM Adapter Cable is needed. See Section 2.5.

MOUSE
For each submaster you plan to connect, you
must have an Expansion Cable; you must have
an Adapter Cable for each CPU you plan to
connect. See Section 2.5.
NOTE
The 2-port (mini) chassis has 4 CPU N
connector slots; the slimline-model
chassis has 8 of these slots, and the
full-size chassis has 16 of them. The
extra connector slots in the chassis of
the 2-port, 4-port slim, and 8- and
12-port full-size models are left blank,
but are protected by material mounted
inside the chassis.
