Rear-Panel Ports and LEDs

This section describes the router rear panel ports and LEDs, which are shown in Figure 1-2

and described in Table 1-2 and Table 1-3.

Ethernet port 10/100

ETHERNET

(yellow)

Connects the router to the local Ethernet network through this

port. This port autosenses the speed (10 Mbps or 100 Mbps) and

duplex mode (full- or half-) of the device to which it is connected

and then operates at the same speed and in the same duplex

mode.

Auxiliary port AUX

Front-Panel LEDs

Use the router front-panel LEDs to determine network activity and status on the Ethernet

port and on the WAN interface card ports. The front-panel LEDs are illustrated in

Figure 1-3 and described in Table 1-4.

LED Label Color Description

PWR Green On means that DC power is being supplied to the router.

OK Green On means that the router has successfully booted up and the software is functional.

This LED blinks during the power-on self-test (POST).

Refer to Table 3-1 in the “Troubleshooting” chapter for information on how to use

this LED for router diagnostics.

Router Memory

Cisco 1700 Router Hardware Installation Guide

1-8

Router Memory

This section describes the types of memory stored in the router and how to ﬁnd out how

much of each type of memory is stored in the router.

For instruction on how to upgrade memory in the router, refer to the “Installing and

Upgrading Router Memory” appendix later in this guide.

Types of Memory

The Cisco 1700 router has the following types of memory:

•Dynamic random-access memory (DRAM)—This is the main storage memory for the

router. DRAM is also called working storage and contains the dynamic conﬁguration

information. The Cisco 1700 router stores a working copy of Cisco IOS software,

dynamic conﬁguration information, and routing table information in DRAM.

•Nonvolatile random-access memory (NVRAM)—This type of memory contains a

backup copy of your conﬁguration. If the power is lost or the router is turned off, this

backup copy enables the router to return to operation without reconﬁguration.

•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 Cisco 1700 router is stored on mini-Flash modules.

Amounts of Memory

Use the show version command to view the amount of DRAM, NVRAM, and Flash

memory stored in your router. The following example of the show version command

output in bold text displays the amount of memory stored in this router.
