NRZ. To configure for NRZI mode on each port, the jumper must connect pins 1 and 2 of the respective jumper locations. (See Figure 2-22.) For NRZ (not NRZI), the jumpers that connect pins 2 and 3 can be removed. 2-20 Cisco 4000 Series Hardware Installation and Maintenance...
Network Connection Considerations If the network processor module is operating as DTE in NRZI mode, the sense of the dte-invert-timing command must be manually changed. For instance, if the command no dte-invert-timing was previously entered in the configuration file, then dte-invert-timing must be configured for the module to operate as DTE in NRZI mode.

Network Connection Considerations BRI Connections The BRI network processor module (see Figure 2-31 and Figure 2-30) supports 8 Basic Rate Interface (BRI) ports. Each BRI port is an RJ-45 8-pin connector. Use an appropriate cable to connect the BRI module directly to an Integrated Services Digital Network (ISDN) through an ISDN channel service unit/digital service unit (CSU/DSU) called the NT1.
Channelized T1 Connections The Cisco 4000 series router supports a channelized T1 (CT1) network processor module with one T1 interface.The CT1 provides one channelized T1 connection via a serial cable to a channel service unit (CSU). On the CT1, the controller provides up to 24 virtual channels. Each virtual channel is presented to the system as a serial interface that can be configured individually.
Complies with all AT&T Accunet TR 62411 specifications T1 Cabling For the CT1, two standard T1 serial cables are available from Cisco Systems: null-modem and straight-through. A straight through cable connects your router to an external CSU. Null modem cables are used for back-to-back operation and testing.
Network Connection Considerations Channelized E1 Connections The Cisco 4000 series router supports a channelized E1 (CE1) network processor module with one E1 interface.The CE1 provides one channelized E1 connection via a serial cable to a channel service unit (CSU). On the CE1, the controller provides up to 24 virtual channels. Each virtual channel is presented to the system as a serial interface that can be configured individually.
E1 Cabling For the CE1 module, four serial cables are available from Cisco Systems. All three have DB-15 connectors on the CE1end and either BNC, DB-15, Twinax, or RJ-45 connectors on the network end.
(with RJ-45 Connector) ATM Connections The ATM processor module for a Cisco 4000 series router provides a user network interface (UNI) between the router and an ATM network. The ATM module provides an interface to ATM switching fabrics for transmitting and receiving data at rates of up to 155 Mbps in each direction (Rx and Tx);...
Page 57
Note Traffic from multiple ATM interfaces could exceed the available bandwidth in the router, causing packets to be dropped. Therefore the Cisco 4500-M and Cisco 4700 routers currently support one ATM module. ATM Cabling For single- or multi-mode SONET connections, connect the fiber cable to the SC-style receptacle on the module front panel.
Inspecting the System The ATM processor module for the Cisco 4000 series router uses identical duplex SC Note connectors for single mode and multi-mode SONET connections. The front panels are similar in appearance. The best way to tell the difference is the yellow laser warning label on the single-mode module’s front panel, or the specific part number visible on the upper surface of all PLIMs.
C H A P T E R Installing the Router This chapter describes the tasks you must perform to install your system. Sections of this chapter follow: • Rack-Mount and Wall-Mount Procedures Overview • Making Console Port Connections • Making Network Connections •...
Flow control is not possible on the console port; however, you can specify padding for output Note characters with the EXEC command terminal [no] padding, which sets character padding on the current terminal line. For details on specifying padding, refer to the appropriate Cisco IOS publication. Making Network Connections Make the network connections by attaching the network interface cables to the appropriate connector on the network processor modules.
Making Network Connections Making Ethernet Connections Ethernet network processor modules contain both Ethernet AUI connectors and 10BaseT connectors. Dual Ethernet modules contain two of each type of connector interface. For dual-port Ethernet modules (see Figure 3-2), connect either the Ethernet AUI connector or the 10BaseT connector on a specific Ethernet port, but not both connectors on the same port.
(See Figure 3-5 and Figure 3-6.) Attach the EIA/TIA-232, EIA/TIA-449, V.35, X.21, or EIA-530 end of the cable to the Step 2 channel service unit/data service unit (CSU/DSU) or modem. 3-4 Cisco 4000 Series Hardware Installation and Maintenance...

Making Network Connections Network hazardous voltages are accessible in the BRI cable. If you detach the BRI cable, Warning detach the end away from the router first to avoid possible electric shock. Network hazardous voltages are also accessible on the BRI module in the area of the BRI port (RJ-45 connector), even when power is turned OFF.

Cisco Systems throughout Europe. The BRI module is a self-contained product that provides all of the hardware necessary to allow connection of Cisco Systems’ chassis to either four or eight Basic Access Integrated Switched Digital Networks (ISDN), each at the S reference point. The ISDN usage is restricted to the point-to-point mode only.
Page 67
In certain countries, the BRI network processor module must be hardwired permanently to the S-reference connection point (your Cisco Systems dealer will advise). This is accommodated for by the use of a connect one-time-only, nonremovable plug (RJ-45 with the latch tab removed).
Note that in Figure 3-9, X indicates the clearance distances between cards and adjacent cards and components, and Y shows the creepage path across the surface of an insulator and between the two points indicated by X. 3-10 Cisco 4000 Series Hardware Installation and Maintenance...
Failure to install the BRI modules in accordance with these instructions will invalidate any telecommunication terminal equipment type approval(s). If you have any doubt as to how to safely install the Cisco Systems BRI module correctly within a host chassis, seek advice from a qualified telecommunications engineer.

Locate the shared-memory SIMM card socket shown on the left of the motherboard as Step 5 shown in Figure 5-5 (for the Cisco 4000-M) and Figure 5-6 (for the Cisco 4500-M and Cisco 4700). Turn the chassis so that the rear of the chassis is closest to you.
Handle SIMMs by the card edges only. SIMMs are sensitive components and can be Caution shorted by mishandling. Hold the SIMM with the connector edge at the bottom, component side facing you, and the Step 6 polarization notch on the left. (See Figure 5-10.) 5-14 Cisco 4000 Series Hardware Installation and Maintenance...

Removing the Cisco 4500-M and Cisco 4700 Boot Helper Flash Memory SIMM The boot helper image (Rxboot image) is stored in Flash memory on the Cisco 4500-M and Cisco 4700. Take the following steps to replace the 4-MB SIMM with an 8–MB or 16-MB SIMM. (See Figure 5-11.)
Memory Replacement Procedures Installing Flash-Memory SIMMs You upgrade boot helper Flash memory by replacing the existing SIMM (labeled System Flash Memory 0), or by adding a second SIMM to the empty socket (labeled System Flash Memory 1). Take the following steps to add Flash-memory SIMMs: On the motherboard, locate the Flash-memory SIMM sockets shown in Figure 5-5 and Step 1 Figure 5-6.
Check the alignment of each SIMM to make sure that it is straight and that the alignment Step 4 holes are lined up with the plastic socket guides. If you have completed all memory upgrade procedures, proceed to the section “Replacing Network Processor Modules” later in this chapter. 5-18 Cisco 4000 Series Hardware Installation and Maintenance...
Memory Replacement Procedures Replacing Boot ROMs in the Cisco 4000-M To upgrade the boot read-only memory (ROM) software to a new software image, the existing boot ROMs must be replaced. Open the chassis and expose the boot ROMs following the procedures in the section Step 1 “Accessing the Router Internal Components”...
If you suspect that your boot ROMs were inserted incorrectly, reopen the chassis, locate the affected boot ROM and remove it, straighten its pins, reinsert the boot ROM, and try booting again. 5-20 Cisco 4000 Series Hardware Installation and Maintenance...

Virtual Configuration Register Settings The Cisco 4000 series has a 16-bit virtual register, which is written into the nonvolatile random access memory (NVRAM). Use the processor configuration register information contained in this appendix to do the following: •...
Reboot the router. The new value takes effect. Configuration register changes take effect only when the server restarts, for example, when you switch the power off and on or when you issue a reload command from the console. B-2 Cisco 4000 Series Hardware Installation and Maintenance...
Enables boot system commands that override default netboot filename 1. Values of the boot field are 2–15 in the form cisco<n>-processor_name, where 2 < n < 15. The boot field specifies a number in binary. If you set the boot field value to 0, you must have console port access to boot the operating system manually.
The server creates a default boot filename as part of the automatic configuration processes. To form the boot filename, the server starts with cisco and links the octal equivalent of the boot field number, a dash, and the processor-type name. Table B-3 lists the default boot filenames or actions for the processor.
Table B-5 shows the bit settings for the four available baud rates. (The factory-set default baud rate is 9600.) Table B-5 System Console Terminal Baud Rate Settings Baud Bit 12 Bit 11 9600 4800 1200 2400 Cisco 4000 Series Virtual Configuration Register B-5...

A P P E N D I X Cisco 4000-M ROM Monitor This appendix describes the Cisco 4000-M ROM monitor, also known as the bootstrap program. The ROM monitor can help you isolate or rule out hardware problems encountered when installing your router.
Modifiers may be R (register) or S (byte swap). Register names are: D0-D7, A0-A7, SS, US, SR, and PC. The following Cisco 4000-M ROM monitor commands are among the most useful: • Boot—The b command with no argument reboots the system and boots the default software from ROM as defined by the lower four bits of the configuration register, which form the boot field.
Entering the Cisco 4000-M ROM Monitor Program • Display/Reset Virtual Configuration Register—The o command displays the virtual configuration register. The o command used with the /r option will reset the configuration register to the default and cause the system software image to ignore the configuration register information (sets the ignore NVRAM contents bit, 0x0040).
