Ethernet Port
The front craft Ethernet interface was designed for a temporary
connection. It allows you to send via FTP software or configurations or
from a locally attached PC without disconnecting from the DB-9 RS-232
connector. It allows you to open a TELNET session through the Ethernet
port so that TL1 commands can be used to configure or retrieve
information.
The rear SP module also contains two Ethernet connectors labeled SIG
ENET (signaling) and OS ENET (operating system) that are controlled by
the system processor. For information about these connectors, refer to the
Rear System Processor section of this chapter.
The IP addresses must first be configured using the RS-232 craft interface
and TL1. Once provisioned, the addresses can be edited using the craft
port TL1 commands or EMS.
5.3.3.4 Redundancy
Control
The SP and SF modules are treated as one entity for the purposes of
failover. For example, if a switch fabric fault is isolated, then the software
will instigate a failover of both modules, and the ATM cell interfaces will
start receiving from the former protection switch fabric. This selection is
performed in the hardware.
