Key Features

The Cisco 815 integrated services router (see Figure 1-1) is a small, modular desktop router that provides an integrated cable solution. The Cisco 815 integrated services router communicates over a cable hybrid fiber coaxial (HFC) network for office-to-Internet connectivity or branch-to-branch connectivity. The Cisco cable modem high-speed WAN interface cards (HWICs) are installed in the router as a fixed configuration for one HWIC full-feature cable modem high-speed interaction, including quality of service (QoS) functionality.

Kensington security slot

Router can be secured to a desktop or other surface using Kensington lockdown equipment.

Support for Cisco IOS software features

Supports IP, IPX, AppleTalk, IBM, Open Shortest Path First (OSPF) Protocol, NetWare Link Services Protocol (NLSP), Resource Reservation Protocol (RSVP), encryption, network address translation, and the Cisco IOS Firewall Feature Set.

1 The HWIC-CABLE-D-2 operates only in WIC mode with 8-Mbps downstream throughput.


Product Serial Number Location

The serial number label for the Cisco 815 integrated services router is located on the rear of the chassis, to the right of the power switch. (See Figure 1-2)

Back Panel Ports and LEDs

This section describes the router back panel ports and LEDs, which are shown and identified in Figure 1-3 and are described in Table 1-2 and Table 1-3. Figure 1-4 shows a closer view of the WIC-4ESW module, which is installed in the WIC 0 slot on the router. Figure 1-5 shows a closer view of the HWIC-CABLE-D-2 module, which is installed in the WIC 1 slot on the router.

Connector/Slot
Label/Color
Description

Ethernet port

10/100 ETHERNET
(yellow)

Connects the router to the local Ethernet network. 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
(black)

Connects to a modem for remote configuration using Cisco IOS software.

Console port

CONSOLE
(blue)

Connects to a terminal or PC for local configuration using Cisco IOS software.

WIC-4ESW (WIC 0)

No label

Supports interface card with four 10/100-BASE-TX Ethernet switchports. See Figure 1-4.

HWIC-CABLE-D-2 (WIC 1)

No label

Supports one Cisco cable WIC. See Figure 1-5.


Use the back panel LEDs during router installation to confirm that you have correctly connected all the cables to the router.

Table 1-3 Back Panel LEDs 

LED Label
Color
Description

WIC0 OK

Green

On when the WIC is correctly installed in the card slot.

There are 2 LEDS associated with the WIC-4ESW: The right LED, which is labeled LNK, and the left LED, which is labeled ACT. The LNK (physical layer link) LED is on when the Cisco IOS software recognizes the switch and the connection is up. The ACT (activity) LED indicates that data is being transmitted or received on the slot.

FDX

Green

On solid—Ethernet port is operating in full-duplex mode.

Off—Ethernet port is operating in half-duplex mode.

100

Green

On solid—Ethernet port is operating at 100 Mbps.

Off—Ethernet port is operating at 10 Mbps.

LINK

Green

On when the Ethernet link is up.

MOD OK

Green

On when the VPN hardware encryption module is installed and recognized by the Cisco IOS software.

WIC1 OK

Green

On when the WIC is correctly installed in the card slot.


Front Panel LEDs

Use the router front panel LEDs to determine network activity and status on the Ethernet port and on the WIC ports. The front panel LEDs are shown in Figure 1-6 and described in Table 1-4.

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, see Appendix C, "Installing and Upgrading Memory and Virtual Private Network Modules."

Types of Memory

The Cisco 815 integrated services 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. It contains the dynamic configuration information. The DRAM in the Cisco 815 integrated services router stores a working copy of the Cisco IOS software, dynamic configuration information, and routing table information.

•Nonvolatile random-access memory (NVRAM)—This type of memory contains a backup copy of the router 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.

Amounts of Memory

The Cisco 815 integrated services router supports a maximum of 32 MB of flash memory and 128 MB of DRAM. Use the show version command to see how much DRAM, NVRAM, and flash memory is stored in your router. The following example of output for the show version command shows the amount of memory in this router:
