The HP Jetdirect 640n Print Server
The HP Jetdirect 640n Print Server provides a single RJ-45 connector port for a network connection
using an unshielded, twisted-pair network cable. It also contains a high-speed USB connector on the
front panel.
Figure 1-1 HP Jetdirect 640n Print Server
The HP Jetdirect 640n Print Server supports connection to IEEE 802.3 10Base-T, IEEE 802.3u
100Base-TX Fast Ethernet and 802.3ab 1000Base-T Gigabit Ethernet compliant networks. When
connected and powered on, the print server auto-negotiates with your network to operate with a link
speed of either 10, 100, or 1000 Mbps, and to communicate using full- or half-duplex mode. However,
you can manually configure the link using the printer control panel, or through other configuration
tools once network communications is established.
The HP Jetdirect 640n Print Server can support multiple network protocols simultaneously, including
TCP/IPv4, TCP/IPv6, IPX/SPX, AppleTalk (EtherTalk), and DLC/LLC. For security, the print server
includes features to control IP traffic to and from the device and supports configuration of IP Security
(IPsec) protocols.
NOTE: By factory default, only TCP/IP is enabled; other network protocols are disabled.
