Port Modules
Port modules are available with either DB-25 or RJ-45 female port
connectors. Both types of port modules may be freely intermixed on a
host cable. A maximum of 4 port modules (64 ports) is permitted for each
PCI MUX 64-port card.
Figure 1-4 illustrates a 16 port DB-25 port module and a 16 port RJ-45
port module.
Port module power is provided by an external power supply
(J2483-60010) connected to the first port module (see Figure 1-3). Power
is passed from left to right through all directly mated modules.
