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.

Troubleshooting ISDN
Because ISDN uses many variables and supports many different configurations, it
sometimes can cause problems for the router. This section describes problems
related to the ISDN line that might occur.
Two commands are useful when troubleshooting ISDN:
• For routers with an ISDN S/T WIC, enter the clear interface command to
terminate any active ISDN calls and to reset the ISDN BRI interface. Do this
for each ISDN port installed in the router:
• For routers with an ISDN U WIC, use the clear controller command to
terminate any active ISDN calls, to reset the ISDN BRI interface, and to reset
the ISDN line between the router and the central office switch. Do this for
each ISDN port installed in the router:
