Control Plane Ports
Each TX-CIP contains four RJ-45 ports labeled
LCC0
through
LCC3
. These ports provide
T640 router control by connecting to T-CBs in up to four T640 routers through UTP
Category 5 Ethernet cables.
TX-CIP-0
and
TX-CIP-1
are used to connect to
T-CB-0
and
T-CB-1 in each T640 router.
NOTE: The RJ-45 ports labeled
LCC4
through
LCC7
on a TX-CIP are reserved
for future use.
Routing Engine Ports
Each TX-CIP has three ports for connecting the corresponding host subsystem to external
management devices (see Figure 21 on page 39). From these management devices, you
can use the CLI to configure the TX Matrix router. The ports on
TX-CIP-0
connect to the
Routing Engine in slot
RE0
, and the ports on
TX-CIP-1
connect to the Routing Engine in
slot
RE1
.
• One 10/100-Mbps ETHERNET port for connecting to a management network—Connects
the Routing Engine through an Ethernet connection to a management LAN (or any
other device that plugs into an Ethernet connection) for out-of-band management.
The port uses an autosensing RJ-45 connector to support both 10- and 100-Mbps
connections. Two small LEDs on the left edge of the port indicate the connection in
use: the LED labeled
ETHERNET lights yellow or green for a 10-Mbps or 100-Mbps
connection, and the LED labeled ACT lights green when traffic is passing through the
port.
NOTE: If a TX Matrix router contains two host subsystems, connect both
TX-CIPs to your external management network.
• CONSOLE —One asynchronous serial port for connecting the Routing Engine to a system
console through an RS-232 (EIA-232) serial cable.
• AUXILIARY
—One asynchronous serial port for connecting the Routing Engine to a
laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable.
Alarm Relay Contacts
Each TX-CIP has two alarm relay contacts—labeled
RED ALARM
and
YELLOW ALARM
—for
connecting the TX Matrix router to external alarm devices (see Figure 21 on page 39).
Whenever a system condition triggers either the red or yellow alarm on the craft interface,
the alarm relay contacts are also activated. The alarm relay contacts are located below
the Routing Engine ports.
