Product Overview
The Cisco 805 router can connect a remote office to a corporate office or a small professional office to an Internet service provider (ISP).
In the remote-office-to-corporate-office network, the remote office is typically a small professional office that is part of a largercorporation,suchasarealestateoffice. Although amajorityof its datamightexist attheremote officeitself,the remoteofficemightalso need to exchange data with its larger corporate office. As a result, the remote office needs a connection to the corporate office.
In the small-office-to-ISP network, the small office is typically a small, independent professional office,suchasa small architectural firm that needs to accessinformationfrom the Internet.
Features
Table 1-1 summarizes the features of the Cisco 805 router.
Table 1-1 Cisco 805 Feature Summary Feature Description

Ease of installation Color-coded ports and cables reduce the chance of error. Cisco IOS software Router supports a subset of Cisco IOS software. Cisco 805 Fast Step
software
Provides a Windows 95, Windows 98, and Windows NT software
tool for basic Cisco 805 configuration. Cable lock Provides a way to physically secure router. Locking power connector Locks power connector in place. Wall-mount feature Brackets on router bottom provide a way to mount router on wall or
vertical surface.
1 An additional 4 or 8 MB of Flash memory and DRAM can be added at the factory or later. You can order
upgrade kits and have qualified personnel add the memory. The Cisco product number for the 4-MB Flash memory upgrade kit is MEM805-4U8F, for the 8-MB Flash memory upgrade kit it is MEM805-4U12F, for the 4-MB DRAM upgrade kit it is MEM805-8U12D, and for the 8-MB DRAM upgrade kit it is MEM805-8U16D. (Because of the height of the actual DRAM component, you must order the additional DRAM from Cisco.)

Back Panel
Figure 1-2 describes the Cisco 805 back panel. If the symbol of suitability ( ) appears above a port, you can connect the port directly to a
public network that follows the European Union standards. If the symbol of suitability with an overlaid cross ( ) appears above a port, you must not
connect the port to a public network that follows the European Union standards. Connecting the port to this type of public network can cause severe injury or damage your router.

With the HUB/NO HUB button, you can connect hubs, servers, PCs, and workstations using the yellow Ethernet (straight-through) cable instead of using a crossoverEthernet cable, which you would need to supply. This button identifies the device that you connect to the router Ethernet port using the yellow Ethernet cable. Setting the button to HUB (in) indicates that you are connecting a hub; setting the buttonto NO HUB (out) indicates that you are connecting a server, PC, or workstation. The default setting of this buttonis HUB. If you resetthe button toNO HUB, the router Ethernet connector crosses over the signals transmitted to and received from the yellow Ethernet cable. For information on how the setting of an equivalent hub button can affect the setting of this router button, refer to the “Connecting an Ethernet Device” section in Chapter 2, “Installing the Cisco 805 Router.”
