Before Installing the Router

The Cisco 1721 router is shipped ready for desktop mounting. Before making the power and network connections, simply set the router on a desktop, shelf, or other flat surface.

Note For instructions on wall-mounting the router, see the "Wall-Mounting" section later in this chapter.

Be sure to read the safety information in the Regulatory Compliance and Safety Information for Cisco 1700 Routers document that came with your router.

Warning Read the installation instructions before you connect the system to its power source.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Caution Do not place anything on top of the router that weighs more than 10 pounds (4.5 kg). Excessive weight on top of the router could damage the chassis.

Connecting the Router to Your Local Network

The Cisco 1721 router is connected to your local Ethernet network through the yellow 10/100 Ethernet port. You must provide the following items for this connection:

•A straight-through, RJ-45-to-RJ-45, Ethernet cable

•A 10/100-Mbps Ethernet hub or switch

Warning The ports labeled 10/100 ETHERNET and CONSOLE are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuits to the telephone network voltage (TNV) circuits. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information for Cisco 1700 Routers document that came with the router.)

Caution Always connect the Ethernet cable to the yellow ports on the router. Do not connect the cable to an ISDN S/T or U port (on a WIC) or to an NT-1 that is connected to a WIC. Accidentally connecting the cable to the wrong port can damage your router.

Follow these steps to connect the router to the local network:

Step 1 Connect one end of the cable to the yellow Ethernet port (labeled 10/100 ETHERNET), as shown in Figure 2-1.

Figure 2-1 Connecting the Router to the Local Network

Step 2 Connect the other end of the cable to a network port on the hub or switch.

Installing WICs

The Cisco 1721 router supports one or two Cisco WAN interface cards (WICs). Each card has one or two WAN ports. This section describes the general procedure for installing a card in the Cisco 1721 router.

Note For details on specific WICs, how to connect the card to the WAN line, and how to configure the interface with Cisco IOS software, refer to the Cisco WAN Interface Cards Hardware Installation Guide that came with the card(s).

Safety Information

This section lists safety warnings that you should be aware of before installing WICs in the router.

Warning Only trained and qualified personnel should be allowed to install or replace this equipment. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information for Cisco 1700 Routers document that came with the router.)

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information for Cisco 1700 Routers document that came with the router.)

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information for Cisco 1700 Routers document that came with the router.)

Caution Do not connect a WAN cable to the card until you have completed the installation procedure.

WIC Installation

This section describes how to install WICs in the router.

Installing the Cards in Correct Sequence

The Cisco 1721 router discovers interfaces on WICs installed in the WIC0 slot before it discovers those installed in the WIC1 slot. This can affect your router configuration. This section describes how to ensure that your existing router configuration is not affected when you install WICs.

If you are installing a WIC in the router for the first time, install the card in the WIC0 slot to ensure that your software configuration will not be affected if you install a second card at a later time.

If you are installing a second WIC in a Cisco 1721 that has a card installed in the WIC1 slot, follow this general procedure to prevent having to reconfigure your router:

Caution Read the instructions in the following section, "Installing the Cards," before you install the cards.

Step 1 Remove the installed card from the WIC1 slot.

Step 2 Reinstall the card (removed in Step 1) in the WIC0 slot.

Step 3 Install the new card in the WIC1 slot.

Installing the Cards

Follow these steps to install the card in a Cisco 1721 router:

Step 1 Make sure that the power switch is set to the STANDBY position ( ) and that the power cable is not connected to the power socket on the rear panel.

Caution Power must be removed from the system prior to installing or removing WICs to avoid damaging them. When WICs are pushed into or pulled out of a router that is powered up, there is a very good chance that they could be damaged electrically and will no longer function.

Step 2 Loosen the thumbscrews on the WIC slot cover on the rear panel, as shown in Figure 2-2, and then remove the slot cover. You should be able to loosen the screws using your fingers; however, if the screws are very tight, you might need to use a Phillips screwdriver.

Figure 2-2 Removing the WIC Slot Cover

Step 3 Hold the WIC by the edges on either side of the card front panel, and line up the card edges with the guides inside the card slot, as shown in Figure 2-3.

Figure 2-3 Inserting a WIC in the Router

Step 4 Insert the card in the slot and gently push it into the router until the front panel of the card is flush with the rear panel of the router.

Step 5 Tighten the screws.

Connecting Power to the Router

Read the following warnings before connecting the router to power.

Warning The power supply is designed to work with TN power systems.

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120VAC, 15AU.S. (240VAC, 16A international) is used on the phase conductors (all current-carrying conductors).

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.

Take the following steps to connect power to the router and to turn the router on:

Step 1 Connect the attached power-supply cord to the power socket (labeled +5, +12, -12 VDC) on the router rear panel, as shown in Figure 2-4.

Figure 2-4 Connecting the Power Supply

Step 2 Connect one end of the separate power cord to the socket on the power supply.

Step 3 Connect the other end of the separate power cord to a power outlet.

Step 4 Press the router power switch to ON ( | ).

Step 5 Confirm that the router has power by checking that the PWR LED on the front panel is on.

Verifying Your Installation

You can verify that you have correctly installed the router by checking the following LEDs:

•PWR (front panel)—On when power is being supplied to the router.

•OK (front panel)—On when the router software is loaded and functional. Blinking means that the router is performing a power-on self-test (POST).

•WIC0/WIC1 OK (back panel)—On when a WIC is correctly installed in the corresponding WIC slot.

•ETH ACT (front panel)—Blinking when there is network traffic on the local 10/100 Ethernet LAN.

•WIC0ACT or WIC1 ACT (front panel)—Varies, depending on the WIC installed. Refer to Table 1-4 in "Cisco 1721 Router Overview."

•LINK (back panel)—On when the router is correctly connected to the local Ethernet LAN through the 10/100 ETHERNET port.

•MOD OK (back panel)—On when the VPN hardware encryption module is installed and recognized by the IOS.

Optional Installation Steps

This section describes some installation steps that you might or might not use, depending on your site and on how you are configuring the router. This section describes the following procedures:

•Connecting a PC

•Connecting a Modem

•Wall-Mounting

•Stacking the Router

•Unstacking the Router

Connecting a PC

If you want to configure the router by using the Cisco IOS command-line interface, you must connect the router console port to a terminal or PC. The cable and adapter required for this connection are included with the router.

To configure the router by using a PC, the PC must have some type of terminal emulation software installed. The software should be configured with the following parameters: 9600 baud, 8 data bits, no parity bits, 1 stop bit. Refer to the Cisco 1700 Router Software Configuration Guide that came with your router for detailed information about configuring the router using Cisco IOS software.

Follow these steps to connect the router to a terminal or PC:

Step 1 Connect the blue console cable to the blue console port on the back of the router, as shown in Figure 2-5.

Figure 2-5 Connecting the Console Cable to the Router

Step 2 Connect the DB-9 end of the console cable to the console port (also called the serial port) on your PC. If this adapter does not fit your PC console port, you must provide an adapter that fits.

Connecting a Modem

When a modem is connected to the auxiliary port, a remote user can dial into the router and configure it. You can use the blue console cable that came in the accessory kit.

Follow these steps to connect a modem to the router, using the console cable:

Step 1 Connect the RJ-45 end of the cable to the black AUX port on the back of the router, as shown in Figure 2-6.

Figure 2-6 Connecting a Modem to the Router

Step 2 Connect the DB-9 end of the cable to the DB-9 end of the DB-9-to-DB-25 adapter.

Step 3 Connect the DB-25 end of the adapter to the modem.

Wall-Mounting

The Cisco 1721 router can be wall-mounted using two number six, 3/4-inch screws and the molded mounting brackets on the bottom of the hub, as shown in Figure 2-7. You must provide the screws. We recommend using pan-head or round-head screws.

Figure 2-7 Wall-Mount Brackets—Bottom of Router

To mount the router on a wall or other surface:

Step 1 Install the two screws 3.75 inches (9.52 centimeters) horizontally apart on a wall or other vertical surface.

The screws should protrude 0.25 inch (0.64 centimeter) from the surface of the wall.

Step 2 Hang the router on the screws with either the left side or right side mounting brackets so that

•The LEDs are visible to the user—Because the LEDs indicate the router operating status, they need to be easily visible.

•The power supply does not hang from its cable—If the power supply is not supported, it might disconnect from the cable that connects it to the router.

Caution If you install the screws in drywall, use hollow wall anchors (1/8 inch by 5/16 inch) to secure the screws. If the screws are not properly anchored, the strain of the cables connected to the router rear-panel connectors could pull the router from the wall.

Stacking the Router

You can stack one Cisco 1721 router in a four-device stack, along with other Cisco products designed to be stacked with the router. You can stack each device directly on top of another device.

Note The Cisco 1721 router is not shipped with the stacking equipment described in this section; however, the equipment is included with all other Cisco products that are designed to be stacked.

Each Cisco product designed to be stacked with the router comes with a stacking clip and a fastener for keeping the multiple devices together in a stack. Before you stack the devices, assemble the clip and fastener as shown in Figure 2-8.

Figure 2-8 Assembling Stacking Clip and Fastener

After assembling the clip and fastener, follow these steps to to stack the router with another device:

Step 1 Place the clip on top of the lower device, as shown in Figure 2-9. Slide the clip forward so that the front tabs slide into the vent slots. Make sure that the rear hooks fit over the edge of the lower device.

Figure 2-9 Stacking the Router

Step 2 Position the router onto the clips so that the rear hooks fit over the edge of the router.

Step 3 Snap the router to the clip by pushing it down. Make sure that the plastic fastener fits into the bottom of the router.

Unstacking the Router

Follow these steps to unstack the router from another device:

Step 1 Press up on the tab over the center of the lower device to release the clip from the vent, as shown in Figure 2-10.

Figure 2-10 Unstacking the Router

Step 2 Slide the clip and router toward you.

Step 3 Use both hands to lift the router and the stacking clip off the lower device. Afterward, remove the clip from the bottom of the router.
