shows redundant IPT modules using NIMP01 and
NIMP02 Multi-Function Processor Termination Modules. This
configuration gives redundant IPT modules access to the two
RS-232-C channels on the NIMP01 termination module. The
secondary IPT module must access the serial channels on the
NIMP01 termination module through its connection to the
NIMP02 termination module. The primary IPT module controls
the NIMP01 termination module.
Figure
illustrates how redundant IPT modules use two
NTMP01 termination units. This configuration gives each IPT
module control of a termination unit with two RS-232-C serial
channels. Only the primary IPT module will enable its termina-
tion unit. The secondary IPT module will not attempt to enable
its termination unit unless it becomes the primary transfer
module.
