Each WIC has one or two WAN ports and each VIC has one or two voice ports. This section describes the procedure for installing a WIC or a VIC in the router.
Chapter 2 Installation Installing WICs and VICs Warning Caution Do not work on the system or connect or disconnect cables during periods of lightning activity. Do not connect a WAN, telephone or fax cable to the card until you have completed the installation procedure. Follow these steps to remove and insert a card in the router: Step 1 Make sure the router is turned off and is disconnected from the power supply.
Chapter 2 Installation Installing WICs and VICs Step 3 Remove the metal plate that covers the card slot. Step 4 Hold the card 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. Step 5 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 6 Tighten the screws.
Chapter 2 Installation Connecting Power to the Router Connecting Power to the Router Read the following warnings before connecting the power to the router. 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).

(See Figure 2-6.) Step 2 Connect the adapter labeled Modem to the other end of the cable. Step 3 Connect the DB-25 end of the adapter to the modem.
Chapter 2 Installation Optional Installation Steps Wall-Mounting The router can be wall-mounted using two number 6 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 Front panel of router Mounting bracket Bottom of router Mounting bracket 3.75" (9.
Chapter 2 Installation Optional Installation Steps Follow these steps 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 inches (0.64 centimeters) from the surface of the wall. Step 2 Caution 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.
C H A P T E R 3 Troubleshooting Use the information in this chapter to help isolate problems you might encounter with the router or to rule out the router as the source of the problem. This chapter contains the following sections: • Contacting Cisco or Your Reseller • Recovering a Lost Password • Problem Solving Contacting Cisco or Your Reseller If you cannot locate the source of a problem, contact your local reseller for advice.

A P P E N D I X E Installing the Echo Canceler Expansion Modules on Cisco Interface Cards This chapter provides information about the hardware-based echo canceler expansion modules that are available on the enhanced multiflex trunk interface cards on the Cisco 1751 router.
Appendix E Installing the Echo Canceler Expansion Modules on Cisco Interface Cards Echo Echo occurs when the speech energy being generated and transmitted down the signal path is coupled into the receive path from the far end. This causes a speaker to hear the sound of his or her own voice, delayed by the total echo path delay time. In a traditional voice network, voice can reflect back, but it usually goes unnoticed because the delay is so low.
Appendix E Installing the Echo Canceler Expansion Modules on Cisco Interface Cards The following echo canceler expansion modules are available for voice-only support on the 1-port RJ-48 multiflex trunk T1/E1 (VWIC2-1MFT-T1/E1) and on the 2-port RJ-48 multiflex trunk T1/E1(VWIC2-2MFT-T1/E1) interface cards on the Cisco 1751 router.
