3	Route Processor

Before you install your Cisco 12404 Internet router, your installation site should already be prepared.

Ensure that you have considered the following before you install the router:

•Mounted at the left side of the chassis is the fan tray, the exhaust vents should not be blocked.

•Facing the rear of the router, mounted on the left side is the air filter; air flow to the air filter should not be blocked.

•24 inches (61 centimeters) of clearance in front of the chassis may be needed for working with line cards, attaching Network Interface Cables (NICs), the CSF or the RP.

•Location is temperature-controlled, air-conditioned and dust-free.

•Power cables and power supplies have been checked for compatibility with your power service.

•Labels on the equipment have been checked to ensure that the power service at your site is suitable for the Cisco 12404 router.

---

Warning Do not mix power supply input types in the Cisco 12404 router. All power supplies installed in a router must be either AC PEMs or DC PEMs.

---

•AC  and DC power source voltage receptacles are easy to reach.

Rack-Mounting Bracket Installation

Mounting brackets are shipped with every Cisco 12404 router, these brackets are optional; you can install the Cisco 12404 router in the rack without using rack mounting brackets.

Tools Needed

You need the following items to install the optional rack-mounting brackets.

•Number 2 Phillips screwdriver

•Tape measure (optional)

•Level (optional)

Rack-Mounting Bracket Installation

The mounting brackets temporarily bear the weight of the router while it is being positioned in the rack for permanent installation. These brackets can be left in place following router installation.

Two or more people should install the router to minimize the risk of personal injury and damage to the equipment.

Installing the mounting brackets is presented in this section.

---

Step 1 Measure and mark the hole at the same height on both the left and right rack rails.

Step 2 Hold the right bracket against the right mounting rail and align the bottom screw hole in the bracket with the marked screw hole.

Step 3 While supporting the bracket against the mounting rail with one hand, use the other hand to insert a screw through a hole in the rack-mounting bracket.

Step 4 Use your fingers to tighten the screw.

Step 5 Insert a second screw in the top hole in the bracket and finger tighten the screw.

Step 6 Mount the left rack-mounting bracket the same as you mounted the right bracket.

Step 7 Measure the two brackets to ensure they are positioned at the same height.

Step 8 Use a level to ensure the tops of the two brackets are level, or use a measuring tape to ensure that each bracket is the same distance from the top of both rack rails.

Step 9 Use a screwdriver to tighten all the screws (Figure 3-2).

Figure 3-2 Rack-Mounting Brackets

---

Installing the Chassis in a Rack

Installing the Cisco 12404 router in a rack is presented in this section. It is recommended that two people perform the following steps, to mount the chassis in a rack.

This procedure assumes you have unpacked the router using the "Cisco 12404 router Unpacking Instructions" document number 78-13618-01, posted on the outside of the shipping container.

---

Step 1 Move the router as close to the installation location as possible without interfering with the installation process

Step 2 One person should grasp the front and the other person grasp the rear of the chassis, bending your knees as you lift the chassis off of the pallet and position the chassis in the rack.

Step 3 If a third person is needed, have that person install the screws to secure the chassis to the rack.

Step 4 Look at the bottom mounting holes on the chassis. Align one of the holes with a mounting hole in the rack.

Step 5 Install one of the mounting screws provided.

Step 6 On the other side of the chassis adjust the position of the chassis so that the same mounting hole in the bottom group of mounting holes is aligned with a hole in the rack.

Step 7 Install one of the mounting screws provided.

Step 8 Repeat Step 4 through Step 8 for additional mounting holes.

Step 9 Use a screwdriver to tighten all the screws.

---

Center-Mount Brackets

If you plan to install the Cisco 12404 router in the center-mount position, you must first install the center-mount brackets on the equipment rack rails, then secure the chassis to the center-mount brackets.

The optional center-mount bracket installation kit ships in an accessories box included in the Cisco 12404 router shipping container. If any parts are missing, contact a Cisco service representative for assistance.

Required Tools

You need the following items to install the optional center-mount brackets.

•Number 2 Phillips screwdriver

•Tape measure (optional)

•Level (optional)

Center-Mount Brackets

Installation instructions using the optional center-mount brackets are presented in the following steps.

---

Step 1 Measure and mark the hole at the same height on both the left and right posts.

Step 2 Hold the right bracket against the right rack rail and align the bottom screw hole in the bracket with the marked screw hole.

Step 3 While supporting the bracket against the rack rail with one hand, use the other hand to insert a screw through a hole in the center-mount bracket that aligns with a hole on the rack rail.

Step 4 Use your fingers to tighten the screw.

Step 5 Insert a second screw in the top hole in the bracket and finger tighten the screw.

Step 6 Use a screwdriver to tighten all the screws (Figure 3-3).

Figure 3-3 Center-Mount Brackets

Step 7 Mount the left center-mount bracket so that it is at the same height as the right bracket.

Step 8 Use a level to ensure the two brackets are level; or use a measuring tape to ensure the both center-mount brackets are the same distance from the top of both rack mounting rails.

Step 9 Use a screwdriver to tighten all the screws.

---

Installing the Chassis on a Tabletop or Flat Surface

Installing the Cisco 12404 router on a tabletop or stable flat surface is presented in the following steps.

---

Step 1 Move the Cisco 12404 router as close to the installation location as possible.

Step 2 With one person positioned at the front and rear of the chassis, lift the chassis off of the pallet and position the chassis on the flat surface.

Step 3 Secure the chassis to the flat surface to ensure it does not fall off.

---

You can use the same mounting hardware that secured your router to the shipping pallet to secure the chassis to a flat surface.

Supplemental Unit Bonding and Grounding Guidelines

If you are not installing the Cisco 12404 router in a NEBS environment, you can choose to bypass these guidelines and rely on the safety earth ground connection supplied via the 5-15 15A North American plug to the AC power entry modules (PEMs).

Bonding and grounding receptacles are intended to satisfy the Telcordia NEBS requirements for supplemental bonding and grounding connections. The Cisco 12404 router chassis requires a safety earth ground connection as part of the power cabling to the router (Figure 3-4).

Figure 3-4 Supplemental Bonding and Grounding Port for NEBS Compliance

We strongly recommend that you connect the central office (CO) ground system or interior equipment grounding system to the chassis. Grounding to the CO system or your interior equipment grounding system meets the network equipment building system (NEBS) bonding and grounding requirement.

To meet this requirement, crimp a dual-hole lug to #6 AWG cable and connect the lug to the chassis using two 6.3 mm (M6) screws (see Figure 3-4).

---

Note The spacing between the holes on the lug is 0.63 inch (16 mm). A dual-hole lug meeting these specifications can be ordered directly from Cisco (Part Number 32-0607-01).

---

Connecting RP and Line Card Cables

To connect RP and line card cables to the router (Figure 3-5):

---

Step 1 Attach an ESD-preventive strap to yourself and to either the chassis, or to a bare metal surface.

Figure 3-5 RP and Line Card Cable-Management Brackets

Step 2 Proceeding from left to right identify the network interface cables (NIC) that attach to the RP or line card. See Figure 3-5.

Step 3 Carefully route the identified NIC through the cable-management tray and over to the card interface port; do this for one NIC at a time.

Step 4 Proceeding from left to right identify the NIC that connects to each card port and connect the NIC to the RP or line card port.

Step 5 Proceeding from left to right carefully wrap the NIC using the velcro straps.

---

Caution Carefully adjust the interface cable in the RP or line card cable-management bracket to prevent any kinks or sharp bends in the interface cable. Kinks and sharp bends can destroy or degrade the ability of the optical fiber to propagate the signal-encoded beam of light accurately from one end of the cable to the other. Also, allow adequate strain relief in the interface cable.

---

Step 6 Route the NIC across the cable-management bracket.

Step 7 Route the cable to the chassis cable-management bracket mounted to the left side of the chassis (Figure 3-6).

•Use the screws packaged with the chassis cable management bracket kit.

Figure 3-6 Chassis Cable-Management Bracket

Connecting to the Console Port and Auxiliary Ports

This section provides the information for connecting the console to the router. Both Data Set Ready (DSR) and Data Carrier Detect (DCD) signals are active when the system is running. The console port does not support modem control or hardware flow control. The console port requires a straight-through EIA/TIA-232 cable.

GRP Console and Auxiliary Ports

This section provides connection equipment and pin designation information for the console and auxiliary ports on the GRP. There are several models of the GRP that can be used with the Cisco 12404 router: GRP=, GRP-B=, and GRP-C=.

---

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect all console, auxiliary, and Ethernet interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

---

The GRP-C= does not require shielded cables for Class B, EMI compliance.

---

Note To properly maintain Class B, EMI compliance, you must use shielded cables on the console and auxiliary ports of the GRP= and GRP-B=.

---

The GRP has two EIA/TIA-232 ports:

•DCE DB-25 receptacle for connecting a console terminal, and

•DTE DB-25 plug for connecting other DTE devices

The DCE-mode auxiliary console port is a DCE- DB-25 and receptacle is used for connecting a console terminal, which you will need to configure the Cisco 12404 router (Figure 3-7).

Figure 3-7 GRP Console DCE and Auxiliary DTE Port Connections

The DTE-mode auxiliary port is a DTE DB-25 plug for connecting a modem or other DCE device (such as a channel service unit/data service unit (CSU/DSU) or another router) to the Cisco 12404 router.

---

Note The console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

---

Check your terminal's documentation to determine the baud rate of the terminal you plan to use. If your documentation does not specify settings use the following terminal settings.

1. Baud to 9600

2. Data bits to 8

3. Parity to no parity

4. Stop bits to 2

You must use an EIA/TIA-232 DCE console cable to connect the terminal to the console port.

GRP Console Port Signals

The console port on the GRP requires a straight-through EIA/TIA-232 cable. Table 3-1 describes the console port pin signals for the GRP.

Table 3-1 GRP Console Port Pin Signals

Pin	Signal	Input/Output	Description

GRP Auxiliary Port Signals

The auxiliary port on the GRP is a DB-25 plug DTE port for connecting a modem or other DCE device (such as a CSU/DSU or other router) to the Cisco 12404 router.

There are several models of the GRP that can be used with the Cisco 12404 router: the GRP=, the GRP-B=, and the GRP-C=. In order to maintain Class B EMI compliance, shielded cables must be used on the console and auxiliary ports of the GRP= and GRP-B=. The newer GRP-C= does not require shielded cables for Class B compliance.

The auxiliary port is located above the console port on the GRP card. The auxiliary port supports hardware flow control and modem control. An example of a modem connection is shown in Figure 3-7. Auxiliary port signals are listed in Table 3-2.

Table 3-2 GRP Auxiliary Port Signals 

Pin	Signal	Input/Output	Description

PRP Console and Auxiliary Ports

The system console port on the PRP is a DCE RJ-45 receptacle for connecting a data terminal, which you must configure. The console port is labeled Console, as shown in Figure 3-8. Before connecting the console port, check your terminal's documentation to determine the baud rate of the terminal you plan to use.

---

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect all console, auxiliary, Ethernet, and BITS (PRP2) interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

---

Check your terminal's documentation to determine the baud rate of the terminal you plan to use. If your documentation does not specify settings use the following terminal settings:

1. Baud to 9600

2. Data bits to 8

3. Parity to no parity

4. Stop bits to 2

The console port requires a rollover RJ-45 cable.

Installing a Flash Memory Card

By default, a Flash memory card containing a valid Cisco IOS software image is inserted in bottom slot, PCMCIA slot 0 before the router is shipped.

---

Note PCMCIA slot 0 is the bottom slot and slot 1 is the top slot. Both Flash memory card slots on each RP can be used at the same time.

---

The software configuration register is set to 0x0102, which causes the router to boot automatically from the Cisco IOS software image stored on the Flash memory card.

•The Flash memory card that shipped with your system is installed in the bottom slot, PCMCIA slot 0 of the RP. See Figure 3-9.

Figure 3-9 Flash Memory Card Slots

Ensure that a console terminal is connected to the RP console port and turned on, or that you have a remote login to the router from another device through a telnet session.

Connecting the GRP to an Ethernet Network

This section provides information for connecting the GRP to an Ethernet network (Figure 3-10).

Figure 3-10 RJ-45 and MII Ethernet Connections

---

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect all console, auxiliary, and Ethernet interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

---

Warning The ports labeled Ethernet, 10BASE T, Token Ring, Console, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits should only be-connected to other SELV circuits. Because the basic line interface (BRI) circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.

---

Connecting the PRP to an Ethernet Network

This section provides information for connecting the GRP to an Ethernet network.

There are two RJ-45 Ethernet interface receptacles on the PRP, providing media-dependent interface (MDI) Ethernet ports. These connections support IEEE 802.3 and IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

The RJ-45 receptacles on the PRP provide two physical connection options for Ethernet interfaces. RJ-45 cables are not available from Cisco Systems; they are available from outside commercial cable vendors. To connect cables to the PRPs Ethernet interfaces (ports labeled ETH0 and ETH1), attach the Category 5 UTP cable directly to a RJ-45 receptacle on the PRP.

The Ethernet interfaces on the PRP are end-station devices, not repeaters; therefore, you must connect an Ethernet interface to a repeater or hub.

---

Note Only connect cables that comply with EIA/TIA-568 standards. (See Table 3-8 and Table 3-9 for cable recommendations and specifications.)

---

---

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect all console, auxiliary, Ethernet, and BITS (PRP2) interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

---

---

Caution The Ethernet ports are primarily used as a Telnet port into the Cisco 12000 series router, and for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

---

Figure 3-13 is an example of the functionality of an Ethernet port. In this example, you cannot access Network 2.0.0.0 through the Ethernet port (ETH0) on the PRP in router A; you can only access the hosts and router C, which are in Network 1.0.0.0. (See dotted arrows in Figure 3-13.)

To access Network 2.0.0.0 from router A, you must use an interface port on one of your line cards (in this example, a Packet-over-SONET (POS) line card in router A) to go through router B, through router C, and into Network 2.0.0.0. (See solid arrows in Figure 3-13.)

Figure 3-13 Using the Ethernet Port on the PRP

PRP Ethernet Connections

Figure 3-14 shows a PRP RJ-45 receptacle and cable connectors. The RJ-45 connection does not require an external transceiver. The RJ-45 connection requires Category 5 unshielded twisted-pair (UTP) cables, which are not available from Cisco Systems, but are available from commercial cable vendors. Table 3-7 lists the port pinouts for the RJ-45 receptacle.

Figure 3-14 RJ-45 Receptacle and Plug (Horizontal Orientation)

---

Warning The ports labeled Ethernet, 10BASE-T, Token Ring, Console, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.

Connecting to an AC Power Source

This section provides the procedure for connecting your router to an AC power source. A power factor corrector (PFC) allows the PEM to accept AC power source voltage from an AC power source operating between 100-120 VAC, 15-Amp service in North America; and a range of 185-264 VAC, 10-Amp service in an international environment.

---

Caution The AC PEM weighs 14.0 pounds (6.35 kg.). Use two hands when handling a PEM.

---

---

Step 1 Attach an ESD-preventive strap to yourself and to either the chassis, or to a bare metal surface.

Step 2 Using two hands to support and guide the PEM, slide it into the PEM bay. Push the PEM all the way into the bay until the PEM connector engages the backplane connector.

Step 3 Tighten the captive screws on the PEM faceplate (Figure 3-17).

Figure 3-17 AC PEM

1	AC PEM handle	4	Power cord receptacle
2	On/Off switch	5	LEDs
3	Bail Latch	6	Captive screws

•All electrical connections between the power supply and the backplane are made automatically when the power supply is fully inserted in the power supply bay.

Step 4 Locate the AC power cord and remove it from its shipping packaging. Verify that the AC power cord shipped with the power supply is the correct type for your site.

---

Note If you have an incorrect type of power cord, contact your service representative for a replacement.

---

Step 5 Plug the AC power cord into the AC PEM.

Step 6 Connect the other end of the AC power cord to the AC power source outlet.

---

Note We recommend attaching each AC PEM to an independent power source for full redundancy. We also recommend that you use an uninterruptable power source (UPS) to protect against power failures at your site.

---

Step 7 Verify that the AC power source circuit breaker servicing the AC PEM is switched on (Figure 3-18).

---

Caution Turn the AC PEM power switch OFF.

---

Figure 3-18 AC PEM LEDs

1	INPUT OK	Green	AC is present and within specified limits
2	OUTPUT OK	Green	Power supply module is operating normally in a powered up condition
3	OUTPUT FAIL	Amber	Power module is operating in a fault condition and shutdown has occurred

---

Note When operating your router on an AC power source, both PEM bays must have all AC PEMs installed to ensure compliance with regulatory EMI standards.

---

---

Powering On the Router

Power on the router by switching on all the circuit breakers and/or plug the power cord into an active power source that controls power to the router's AC PEM or DC power distribution unit (PDU).

---

Note During the first-time startup, the system displays the system banner information.

---

Checking the Startup

Check the startup banner and displays to ensure that the system has restarted properly and that all the interfaces reinitialize properly. You should observe the power module LEDs shown in figures Figure 3-18. Also, listen for the fans in the fan tray, you should immediately hear them operating. In a noisy environment, the fans might be difficult to hear; therefore, place your hand in front of the exhaust vents at the side of the chassis to verify that the fans are operating.

Visually check the CSF LEDs, MBus LEDs on the CSF, and the RP LEDs on the RP (Figure 3-19).

RP LEDs are located at one end of the RP faceplate, near the ejector lever. Figure 3-25 shows the RP LED displays.

Table 3-10 lists the CSF LEDs.

On the console terminal, verify that the console displays the system banner and that the system and all interfaces initialize successfully.

If the power supplies do not power up, or if the system or any interfaces do not initialize properly, see Chapter 4, "Troubleshooting the Installation." If you are still unable to resolve the problem, contact your Cisco service representative for assistance.

Connecting the Router to a DC Power Source

This section provides the procedure for connecting your router to a DC power source (Figure 3-20).

---

Note We recommend each DC PDU be connected to an independent power source for full redundancy. We also recommend that you use an uninterruptable power source (UPS) to protect against power failures at your site.

Connecting a DC PDU and DC PEM Assembly

Each DC PDU should be connected to separate DC sources using six threaded terminals. Two terminals for negative (source DC), two terminals for positive (source DC return), and two terminals for ground. The DC power cable leads should be 6 American Wiring Gauge (AWG) high strand count wire. The PEM accepts DC power source voltage from a dedicated 35-Amp service DC power source operating between -48 to -60 VDC.

---

Caution The DC PEM and DC PDU assembly weighs 14.0 pounds (6.35 kg.). Use two hands when handling the power supply.

---

---

Warning Power to your router must be Off and all cables disconnected before you install the DC power assembly. The DC PDU and DC PEM when connected, is not a hot-swappable, field replaceable unit.

---

Use this procedure to install the DC PEM and DC PDU in your router. The DC power module housing is located at the rear of the chassis.

---

Step 1 Attach an ESD-preventive strap to yourself and to either the chassis, or to a bare metal surface.

Step 2 Insert the DC power module into the power module bay at the rear of the chassis

Step 3 Press the power supply against the backplane until the connectors are seated against the backplane receptacles.

•Figure 3-21 shows the rear view of a Cisco 12404 router with the DC PDU installed.

Step 4 Tighten all of the captive screws on the faceplate.

•All electrical connections between the power supply and the backplane are made automatically when the power supply is fully inserted in the power supply bay.

Step 5 Use a 1/4-inch screwdriver to tighten the captive screws on the DC PDU (Figure 3-22).

2	Positive Terminal Port	4	Terminal Port Connector Screws

Step 6 Secure each lead to the proper terminal port by tightening the terminal port connector screws with a 3/16-inch flat-blade screw driver.

Step 7 Verify that the DC power source circuit breaker servicing the DC PEM is switched on.

---

Powering On the Router

Power on the router by switching on all the circuit breakers and/or plug the power cord into an active power source that controls power to the router's AC PEM or DC power distribution unit (PDU).

---

Note During the first-time startup, the system displays the system banner information.
