Installing 2T16S Network Processor Modules in the Cisco 4000 Series Software Compatibility Network processor modules must be supported by the appropriate level of system software. The minimum system software version for the 2T16S network processor module is as follows: • 2T16S-RS232 and 2T16S-V.35—Cisco IOS Release 11.2(3)P for synchronous and Cisco IOS Release 11.2(4)P for asynchronous operation • 2T16S-X.21—Cisco IOS Release 11.2(5)P • 2T16S-232V35 and 2T16S-232X21—Cisco IOS Release 11.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series • Locate the room’s emergency power-off switch. Then, if an electrical accident occurs, you can quickly turn OFF the power. • Before working on the system, turn OFF the power and unplug the power cord.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).
Installing 2T16S Network Processor Modules in the Cisco 4000 Series Slot Numbering The chassis contains slots for three network processor modules. These slots correspond to the three slot numbers printed on the front panel of the chassis. (See Figure 3.) Slot numbers represent the order in which the system scans the network processor modules. The location of network processor modules is not slot dependent; you can move any module to any other available slot.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series If the second 2T16S module in Figure 2 was replaced by an Ethernet module, the unit addresses would be as listed in Table 3.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series Warning Before releasing the safety latch, support the component tray from underneath, either on your work surface or with your hands, to prevent personal injury. (See Figure 4.

Installing 2T16S Network Processor Modules in the Cisco 4000 Series Step 2 Grasp the network processor module handle and pull it straight up to lift the module out of its connector. (See Figure 6.) Step 3 Place the removed module on an ESD mat. Caution Do not wiggle the handle of the network processor module, and do not exert any side-to-side pressure because the handle might work loose and damage the network processor module.

H8760 Correct installation showing connectors firmly seated. Step 7 Replace the module mounting screw in its place on the end of the network processor module. (See Figure 6.) Step 8 Replace external rear mounting screws, if used, to attach the module to the rear of the chassis.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series When you face the front of the chassis, the three LEDs (labeled OK) on the lower left correspond to the three network processor modules, if present. (See Figure 2.) When on, these LEDs indicate that the network processor modules are operational. The upper LEDs (labeled DATA) blink to indicate network activity on the respective interfaces.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series High-Speed Serial Ports The two high-speed synchronous serial ports use two 60-pin D-type connectors to attach to the transition cable. Each port requires a serial adapter cable, which provides the interface between the high-speed serial port and the standard connectors that are commonly used for each electrical interface type.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series The adapter cable also determines the electrical interface type and mode (DCE or DTE) of the port to which it is connected. Because the low-speed serial ports require special adapter cables, we recommend that you obtain serial interface cables from Cisco Systems (contact Customer Service at 800 553-6387, 408 526-7208, or cs-rep@cisco.com).
Installing 2T16S Network Processor Modules in the Cisco 4000 Series The data rate depends on the type of electrical interface used. EIA/TIA-232 only supports speeds up to 64 kbps; X.21, V.35, EIA/TIA-449, or EIA-530A support higher speeds. Note that EIA/TIA-449 or EIA-530A interfaces are only supported on the high-speed serial ports. When connecting serial devices, consider the adapter cables as an extension of the router for external connections.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series High-Speed Cable Overview The router-end of the high-speed serial cable is a 60-pin D-sub connector, and the network end reflects the interface type and mode (see Figure 11 and Figure 12 for examples). The high-speed port supports the following DTE cables: CAB-232MT=, CAB-449MT=, CAB-V35MT=, CAB-X21MT=, or CAB-530MT=; the port supports the following DCE cables: CAB-232FC=, CAB-449FC=, CAB-V35FC=, or CAB-X21FC=.

Installing 2T16S Network Processor Modules in the Cisco 4000 Series X.21 Connections The X.21 interface uses a 15-pin connection for balanced circuits and is commonly used in the United Kingdom to connect public data networks. X.21 relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232. The network end of the X.21 adapter cable is a standard DB-15 connector, as shown in Figure 17. X.

Installing 2T16S Network Processor Modules in the Cisco 4000 Series Note The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator to obtain access if necessary. The following sections describe the commands for configuring an external clock signal for a DCE interface and for configuring a port for NRZI encoding or 16-bit cyclic redundancy check (CRC).
Installing 2T16S Network Processor Modules in the Cisco 4000 Series When a port is operating in DCE mode, the default operation is for the attached DTE device to return the clock signal (SCTE) to the DCE port. The DCE sends SCT and SCR clock signals to the DTE, and the DTE returns an SCTE clock signal to the DCE.

Note Step 3 The serial interface numbers for the low-speed ports can be 2 to 17 or 20 to 35 as previously described in Table 1.
Installing 2T16S Network Processor Modules in the Cisco 4000 Series Calculating CRCs on Cisco 4000 Series Serial Interfaces All Cisco 4000 series router serial interfaces support CRC-CCITT, a 16-bit CRC. CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. The sender of a data frame divides the bits in the frame message by a predetermined number to calculate a remainder or frame check sequence (FCS).
Installing 2T16S Network Processor Modules in the Cisco 4000 Series The key to problem solving in this system is to try to isolate the problem to a specific subsystem. By comparing what the system is doing to what it should be doing, the task of isolating a problem is greatly simplified. When problem solving, consider the following subsystems of the router: • Power system—This subsystem includes the power supply and the wiring. • Cooling system—The fan should go on when power is applied.
