Appendix a 1 Cable or DSL modem connecting the networked devices to broadband Internet access 2 A network access point (hub, switch, or router) into which all the devices are connected through ethernet cables Networked devices connect to each other through a central device. The most common types include: ● Hubs: A simple, inexpensive network device that lets several computers communicate with each other or share a common printer. Hubs are passive. They only provide a way for communication to flow between other devices. ● Switches: Switches are similar to hubs, but can examine the information sent between devices and forward the information only to the proper device. They can lessen bandwidth usage on a network and help keep it running more efficiently. ● Routers: Routers or gateways connect both devices and networks. A common use is to connect several home computers on a network to the Internet. Routers often also include a built-in firewall that can help protect a home network from unauthorized access. Note For specific information about setting up and configuring the hardware on your network, see the documentation that came with the hardware. Internet connection If your network is connected to the Internet through a router or gateway, it is recommended that you use a router or gateway that supports Dynamic Host Configuration Protocol (DHCP). A gateway with DHCP support manages a pool of reserved IP addresses that it assigns dynamically as needed. See the documentation that came with the router or gateway. Recommended network configurations The following network configurations support the printer. Determine the type of network configuration you have, then see Connecting the printer to the network and Installing the printer software on a Windows computer or Installing the printer software on a Macintosh for instructions on connecting your printer to the network and then installing the software. Ethernet network without Internet access The computers and printer communicate with each other, forming a simple network, through a hub. None of the networked devices has access to the Internet. Some printer features, such as sharing photos directly from the printer over the Internet using HP Instant Share, do not work in this configuration. 72 HP Photosmart 8400 series

A network access point (hub, switch, or router) into which all the devices are connected through ethernet
cables
Networked devices connect to each other through a central device. The most common types
include:
●
Hubs
: A simple, inexpensive network device that lets several computers communicate with
each other or share a common printer. Hubs are passive. They only provide a way for
communication to flow between other devices.
●
Switches
: Switches are similar to hubs, but can examine the information sent between
devices and forward the information only to the proper device. They can lessen bandwidth
usage on a network and help keep it running more efficiently.
●
Routers
: Routers or gateways connect both devices and networks. A common use is to
connect several home computers on a network to the Internet. Routers often also include a
built-in firewall that can help protect a home network from unauthorized access.
Note
For specific information about setting up and configuring the hardware on your
network, see the documentation that came with the hardware.
Internet connection
If your network is connected to the Internet through a router or gateway, it is recommended that
you use a router or gateway that supports Dynamic Host Configuration Protocol (DHCP). A
gateway with DHCP support manages a pool of reserved IP addresses that it assigns
dynamically as needed. See the documentation that came with the router or gateway.
Recommended network configurations
The following network configurations support the printer. Determine the type of network
configuration you have, then see
Connecting the printer to the network
and
Installing the printer
software on a Windows computer
or
Installing the printer software on a Macintosh
for instructions
on connecting your printer to the network and then installing the software.
Ethernet network without Internet access
The computers and printer communicate with each other, forming a simple network, through a
hub. None of the networked devices has access to the Internet. Some printer features, such as
sharing photos directly from the printer over the Internet using HP Instant Share, do not work in
this configuration.
