The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Router Memory
This section describes the types of memory stored in the router and how to find out how much of each the router has.
For instructions on how to upgrade memory in the router, refer to the “Installing and Upgrading Memory and Data Modules” appendix in this guide.
Types of Memory
The router has the following types of memory:
Dynamic RAM (DRAM)—This is the main storage memory for the router.
DRAM is also called working storage and contains the dynamic configuration information. The router stores a working copy of Cisco IOS software, dynamic configuration information, and routing table information in DRAM.
Nonvolatile RAM (NVRAM)—This type of memory contains the startup
configuration.
Flash memory—This special kind of erasable, programmable memory
contains a copy of the Cisco IOS software. The Flash memory structure can store multiple copies of the Cisco IOS software. You can load a new level of the operating system in every router in your network and then, when convenient, upgrade the whole network to the new level. The Flash memory on the router is stored on mini-Flash modules.

Problem Solving
The key to problem solving is to isolate the problem to a specific subsystem by comparing what the router is doing to what it should be doing.
When problem solving, consider the following subsystems of the router:
WICs and VICs—Refer to the LEDs on the cards and the LEDs on the router
front panel to help identify a failure. For more information on WICs and VICs, refer to the Cisco WAN Interface Cards Hardware Installation Guide that comes with each card.
Cables—Check all the external cables that connect the router to the network.
Power system—Check the external power source, power cable, router power
supply, and circuit breaker. Check for inadequate ventilation or air circulation that might cause overheating.
Cisco 1750 Router Hardware Installation Guide
vi
78-6169-02
ISDN configuration—Consider ISDN-specific hardware and software
configurations (ISDN BRI WICs only).
OK LED Diagnostics
Use the front-panel OK LED to help determine any problems with the router. When the router first boots up, it performs a power-on self-test (POST). If the router detects a problem during the POST, the OK LED blinks in a different pattern (described in Table 1), depending on the problem. A pattern is a specific number of blinks that is repeated until the router is turned off. If the router experiences any of these problems, contact your Cisco reseller.

Warning
Warning
Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.
Do not work on the system or connect or disconnect cables during
periods of lightning activity.
Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.
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.
Only trained and qualified personnel should be allowed to install or replace this equipment.
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first.
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the router. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
