SERVSWITCH™ ULTRA
• You must not cascade submasters to more than one “layer.” That is, you may
connect submasters to the CPU ports of one or (with Matrix ServSwitch
submasters) two master ServSwitches, but do not connect any submasters to
submasters’ CPU ports. To illustrate this restriction, let’s say you’ve installed a
four-port submaster on a four-port ServSwitch master and you have a four-port
submaster yet to install. You must install the second submaster on the master’s
CPU 2 port, not on the first submaster’s CPU 1 port. A third submaster would
have to go on the master’s CPU 3 port, a fourth on the CPU 4 port. If it
becomes necessary to attach more CPUs after “maxing out” on submasters, you
must upgrade your master or submasters.
