1.2 Cisco 6400 Overview

The Cisco 6400 is a broadband concentrator that features Cisco's end-to-end asynchronous transfer mode (ATM) services, Point-to-Point Protocol (PPP) termination, and tunneling. The Cisco 6400 combines Cisco's IOS ATM switching and routing capabilities in a modular, scalable, redundant, Network Equipment Building Systems/European Telecommunication Standards Institute (NEBS/ETSI) compliant chassis.

1.3 Cisco 6400 Physical Description

This section includes detailed information about the following Cisco 6400 components and features:

• Chassis (module compartment, blower compartment, power entry module (PEM) compartment, backplane)

• Node Switch Processor (NSP)

• Node Route Processor (NRP)

• Node Line Card (NLC)

1.3.1 Chassis

The Cisco 6400 chassis, designed for mounting in 19-inch or 23-inch equipment racks, consists of the following:

• Module compartment

• Blower compartment

• PEM compartment

• Backplane (with rear interconnects)

Module Compartment

The module compartment has ten slots: two central slots that are reserved for NSP cards, and eight slots that can accommodate a mixture of full-height NRP cards and full-height and half-height NLCs. All cards support hot-swapping and redundancy. Figure 1-1 shows a fully loaded chassis with redundant cards and power entry modules (PEMs).

Figure 1-1: Cisco 6400 Chassis, Front View

Blower Module

The blower module (Figure 1-2) is located on the top of the chassis and is connected to the backplane. It provides airflow throughout the system. The air intake is located at the bottom of the chassis, and there is an exhaust in the top rear of the chassis through the blower module. The blower module supports hot-swapping and can be replaced without interruption to system operation.

Blower Module LEDs

Power Entry Module

The DC PEM, shown in Figure 1-3, provides filtering and supplies DC power to the chassis electronics. There are two PEM bays in the chassis; however, only one PEM is required. An additional PEM can be used for redundancy. The PEMs are located on the left side of the chassis and are installed from the front. Input source power (-48 VDC from building centralized power source, or from optional AC power shelf) enters the chassis through screw terminals on the rear of the chassis and is supplied to the PEMs when they are plugged into the backplane (see "Installing the AC-Input Power Shelf and Power Supply").

The AC PEM, shown in Figure 1-4, provides power conversion directly from the facility VAC input power to the -48 VDC used internally in the Cisco 6400 chassis. AC power comes into the AC PEM through a power cord attached to the front faceplate.

See "Installing the AC-Input Power Shelf and Power Supply" if the external AC power shelf is used.

Backplane

The backplane is attached to the rear of the Cisco 6400 chassis and provides system interconnect.

NSP LEDs

The LEDs on the NSP indicate the module status conditions. (See Table 1-1.)

Optional Stratum 3 BITS Timing

The NSP with stratum 3 BITS timing (NSP-S3B) supports the same functions and features as the standard NSP, as well as the following:

• Network timing derived from CO BITS or from any NLC interface

• Stratum 3 accuracy when internally timed

Figure 1-6 shows the faceplate of the NSP with stratum 3 BITS timing.

Dual PCMCIA Card Slots

The two PCMCIA card slots can be used to store Cisco IOS software or system configuration information on a Flash disk memory card. The system can also boot from the software stored on the Flash disk memory card.

ACO Switch

The alarm cut-off (ACO) switch is located near the center of the NSP faceplate. Press the switch to turn off audible alarms. You can also disable audible alarms by using the command-line interface (CLI). For more information, refer to the Cisco 6400 UAC Command Reference Guide.

Connectors

The NSP card has three ports with RJ-45 connectors:

• Console port---This asynchronous EIA/TIA-232 serial port can be used to connect the NSP to a terminal, for local administrative access. The RJ-45 connector for the console port is labeled CON.

• Auxiliary port---This asynchronous EIA/TIA-232 serial port can be used to connect the NSP to a modem for remote administrative access. The RJ-45 connector for the auxiliary port is labeled AUX.

• Ethernet port---This port can be used to connect the NSP to a 10BaseT network management LAN. The RJ-45 connector for the Ethernet port is labeled ETH.

Console Port Signals

The console port is a serial EIA/TIA-232 interface. Table 1-2 lists the signals for the console port connector.

Auxiliary Port Signals

The auxiliary port supports hardware flow control and modem control. Table 1-3 lists the signals for the auxiliary port connector.

Network Management Ethernet Port Signals

The network management Ethernet (NME) port provides out-of-band network management of the NSP. Table 1-4 lists the signals for the NME port connector.

1.3.3 Node Route Processor

The NRP (Figure 1-7) receives traffic from one or more NSP ATM switch ports, reassembles the ATM cells into packets, routes the packets, segments the routed packets, and sends them back to the ATM switch. The Cisco 6400 can contain multiple NRP modules, configured to operate independently or as redundant pairs (1+1). NRPs can be inserted into slots 1 through 8 in the Cisco 6400 chassis.

NRP LEDs

The LEDs on the NRP indicate port and module status. (See Table 1-5.)

Connectors

The NRP card has four ports with RJ-45 connectors:

• Console port---Asynchronous EIA/TIA serial port can be used to connect the NRP to a terminal for local administrative access. The RJ-45 connector for the console port is labeled CON.

• Auxiliary port---Asynchronous EIA/TIA serial port can be used to connect the NRP to a modem for remote administrative access. The RJ-45 connector for the auxiliary port is labeled AUX.

• Ethernet port---Can be used to connect the NRP to a 10BaseT network management LAN. The RJ-45 connector for the Ethernet port is labeled ETH.

• Fast Ethernet port---Can be used to connect the NRP to a 100BaseT LAN. The RJ-45 connector for the Fast Ethernet port is labeled FE.

Console Port Signals

The console port is a serial EIA/TIA-232 interface. Table 1-6 lists the signals for the console port connector.

Auxiliary Port Signals

The auxiliary port supports hardware flow control and modem control. Table 1-7 lists the signals for the auxiliary port connector.

1.3.4 Node Line Cards

The Cisco 6400 supports two half-height and one full-height node line card (NLC) modules:

• The OC-3/STM-1 half-height NLC (see Figure 1-8) has two 155-Mbps fiber optic ports for the connection of uplink and downlink interfaces; single mode, intermediate reach.

• The DS3 half-height NLC (see Figure 1-9) has two 45-Mbps bidirectional ports for connection to network services using coaxial cable.

• The OC-12/STM-4 full-height NLC (see Figure 1-10) has one 622-Mbps fiber optic port for the connection of uplink and downlink interfaces; single mode, intermediate reach.

The Cisco 6400 can contain multiple NLC modules, configured to operate independently or as redundant pairs. NLCs can be inserted into slots 1 through 8 (subslots 0 and 1) in the Cisco 6400 chassis.

The three types of NLC can be configured to support the following clocking options:

• Self-timing based on a Stratum 4 level clock

• Loop timing from the received data stream, which is ideal for public network connections

• Timing synchronized to the NSP network clock port; required for distribution of a single clock across a network
