and diagnostic testing and reporting. Only one Fiber Remote Multi-IPE
Interface can be accessed at a time. To access another Fiber Remote
Multi-IPE Interface, the current session has to be terminated and a
different Fiber Remote Multi-IPE Interface unit can then be accessed by
logging in again.
The Fiber Remote Multi-IPE Interface supports the maintenance port
transmission speed of 2400 baud.
If multiple Fiber Remote Multi-IPE Interface units are co-located at a
site, usually at the local site, Fiber Remote Multi-IPE Interface units can
be daisy-chained to allow a single MMI terminal to access any Fiber
Remote Multi-IPE Interface unit in the chain. This is accomplished by
daisy-chaining the MAINT and the SDI ports on each Fiber Remote
Multi-IPE Interface unit.
The SDI port of the first Fiber Remote Multi-IPE Interface in the
daisy-chain can be optionally connected to an SDI port on the SDI card
in the local system. The MAINT port in the last Fiber Remote Multi-IPE
Interface in the daisy-chain is connected to the MMI terminal.
Fiber Remote Multi-IPE Interface units in a daisy-chain have unique
addresses, which are set by a dip-switch setting on the motherboard.
This allows a specific Fiber Remote Multi-IPE Interface in the chain to be
selected when logging in on the MMI terminal to perform configuration,
maintenance, or testing of that Fiber Remote Multi-IPE Interface unit.
System monitor interface
The system monitor cards reside in the local and Remote IPE pedestals.
They monitor the power and the temperature in all modules in the local
column and in the Remote IPE column. The master system monitor
is located in the local common equipment pedestal. It receives the
information from modules in its own column, from the slave system
monitors located in other co-located columns, and from each Remote IPE
system monitor over the fiber-optic link.
The Fiber Remote Multi-IPE Interface I/O panel provides two 6-pin modular
jacks, which are used to connect the system monitor to the Fiber Remote
Multi-IPE Interface for transmission of power and temperature status from
the Remote IPE to the local system over the fiber-optic link.
If multiple Fiber Remote Multi-IPE Interface units are co-located at the
local site, these units are daisy-chained by connecting the XSM OUT
modular jack of one Fiber Remote Multi-IPE Interface unit to the XSM
IN modular jack of the other unit in the chain. Only one Fiber Remote
Multi-IPE Interface unit 6-pin XSM IN (J5) modular jack is connected to
