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.

software
Provides a Windows 95, Windows 98, and Windows NT software
tool for basic Cisco 805 configuration.
Cable lockProvides a way to physically secure router.
Locking power connectorLocks power connector in place.
Wall-mount featureBrackets on router bottom provide a way to mount router on wall or
vertical surface.
1An 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.”
