    M40e Connector Interface Panel (CIP) Description

    The Connector Interface Panel (CIP) is located at the left side of the FPC card cage, as shown in M40e Chassis Description. It houses Routing Engine management ports and alarm relay contacts, as shown in Figure 1.

    The CIP is located on the left side of the M40e and M160 router Flexible PIC Concentrator (FPC) card cage (see Figure 2).

    The CIP is field-replaceable, but is not hot-removable, hot-insertable, or hot-pluggable. You must power down the router before removing or installing it.

    Routing Engine Management Ports

    On the upper half of the CIP are two sets of ports for connecting the Routing Engines to one or more external devices on which system administrators can issue Junos OS command-line interface (CLI) commands to manage the router. The set of ports labeled HOST0 connects to the Routing Engine in the slot labeled RE 0, and the set labeled HOST1 connects to the Routing Engine in the slot labeled RE 1.

    The ports with the indicated label in each set function as follows:

    • ETHERNET—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.
    • CONSOLE—Connects the Routing Engine to a system console through an RS-232 (EIA-232) serial cable.
    • AUXILIARY— Connects the Routing Engine to a laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable.

    For information about the pinouts for the connectors, see RJ-45 Connector Pinouts for the M40e Routing Engine MGMT Port.

    Figure 3 shows the ports that connect to the Routing Engine installed in slot RE 0. The arrangement of ports for the Routing Engine installed in slot RE 1 is the same.

    BITS Input Ports

    In the center of the CIP are two ports labeled BITS A and BITS B (see Figure 4). Use two DB-9 connectors to connect external clock inputs for 19.44-MHz Stratum 3 reference clocks (supported in Junos OS Release 8.3 and later).

    For information about the pinouts for the connectors, see DB-9 Connector Pinouts for the M40e CIP BITS Input Ports. For information about configuring an external synchronization interface, see the Junos OS System Basics Configuration Guide.

    Alarm Relay Contacts

    At the bottom of the CIP are two relay contacts for connecting the router to external alarm-reporting devices, the upper labeled RED ALARM and the lower YELLOW ALARM (see Figure 4). A system condition that causes the red or yellow alarm LED to light on the craft interface also activates the corresponding alarm relay contact. For instructions for attaching a device to the alarm relay contacts, see Replacing Alarm Relay Wires on the M40e Router.
