Related Documentation

The documentation title for the Cisco 837 Router and SOHO 97 Router on the top of page xii of the Preface chapter is incorrect. The correct documentation title should be Cisco 837 Router and SOHO 97 Router Hardware Installation Guide.

Quick Start Guide: Setting Up the Cisco 831 and SOHO 91 Routers

In the Cisco 831 Router and SOHO 91 Router Cabling and Setup Quick Start Guide, the explanation of the purpose of the document Cisco 800 Series Routers Software Configuration Guide is incorrect. This error is on page 2 of the "Easy Installation: Try These Steps First" section. The correct explanation should be as follows:

Cisco 800 Series Routers Software Configuration Guide—Provides detailed configuration instructions for the Cisco 800 series router.

ADSL Cable

In the Cisco 837 Router and SOHO 97 Router Hardware Installation Guide, the lavender ADSL cable mentioned in the "Unpacking the Box" section on page 2-5" of the Installation chapter is an item included with the router. The default lavender ADSL cable that goes with the router box is a straight-through cable. Upon request, the ADSL cable can be changed to a lavender with blue stripe crossover cable.

ADSL Connector Pinouts (RJ-11)

In the Cisco 837 Router and SOHO 97 Router Hardware Installation Guide, the description of the ADSL connector pinouts on page A-3 of Appendix A is incorrect. The correct description is as follow:

Warning Information for China

The Cisco 837 Router and SOHO 97 Router passed the compliance and safety test in China in January, 2003. The following new safety and warning information written in Simplified Chinese should therefore be included in the "Compliance Statement" section starting from page 8 of the Regulatory Compliance and Safety Information for Cisco 800 Series and SOHO Series Routers.

Warning Message

Two of the warning messages listed in the Cisco 836 Router and SOHO 96 Router Hardware Installation Guide and the Regulatory Compliance and Safety Information for Cisco 800 Series and SOHO Series Routers do not exactly match to the router's specification. They should be removed from the warning list.

The first warning message is as follows:


Warning This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming call.

It appears on page 2-3, Chapter 2 Installation of the Cisco 836 Router and SOHO 96 Router Hardware Installation Guide and page 16 of the Regulatory Compliance and Safety Information for Cisco 800 Series and SOHO Series Routers. The warning message is not necessary because the Cisco 836 router and SOHO 96 router do not have a ring signal generator embedded.

The second warning message is as follows:


Warning Network hazardous voltages are present in the ISDN cable. If you detach the ISDN cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the ISDN port (RJ-45 connector), regardless of when power is turned off (by pressing power switch to standby).

It appears on page 2-4, Chapter 2 Installation of the Cisco 836 Router and SOHO 96 Router Hardware Installation Guide and page 22 of the Regulatory Compliance and Safety Information for Cisco 800 Series and SOHO Series Routers. The warning is not necessary because the ISDN cable does not connect to the ISDN wall jack directly, instead, it connects to a NT1 box first, and the NT1 box to the ADSL splitter. The ADSL splitter then connects to the ISDN wall jack through an unshielded Category 5 cable. Therefore, no network hazardous voltages are present in the ISDN cable.

Correction of the Switch

The switch cover wording on the back panel of the Cisco 831, 836 and 837 routers, and the Cisco SOHO 91, 96 and 97 routers is not correct. The words "ON" and "OFF" shown on the switch cover should be "1" and "0" as depicted in Figure 1, Figure 2, and Figure 3. "1" represents power on, while "0" represents power off. The back panel of the Cisco 831, 836 and 837 routers is almost identical to the back panel of the Cisco SOHO 91, 96 and 97 routers. The change on the switch cover will not affect any functionality of the router.

Figure 2 Back Panel of the Cisco 831 Router

Figure 3 Back Panel of the Cisco 836 Router

New Warning Tag on Desktop Power Adapter

A new yellow tag will be attached to the power cord of the desktop power adapter. This tag contains the correct input voltage information to help avoid using the wrong power supply cable when connecting to the Cisco 831, 836 and 837 routers and Cisco SOHO 91, 96 and 97 routers. Always use the desktop power adapter shipped with your router to connect to the router. Refer to Figure 4 for details on the warning message.

Connecting the Power Plug to the Router

Use the power latch provided in the accessory kit to prevent the power adapter plug from disconnecting from the Cisco 831, 836 and 837 routers and Cisco SOHO 91, 96 and 97 routers.

Perform the steps below to slide the power adapter plug into the power latch and connect the plug to the router.


Step 1 Place the cable of the power adapter through the ditch of the power latch as shown in Figure 5.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:
