3.2.3.2 2.5 Gigabit Ethernet interface
The front panel of the CPC505 (see Figure 2-2 ) contains 2 x 10Base-T/100Base- TX/1000Base-
T/2500Base-T Ethernet ports based on 2.5 Gigabit Ethernet i225 network controllers.

– Connector 2.5 Gigabit Ethernet
The interfaces provide automatic baud rate detection and switching between 10Base-T, 100Base-
TX, and 1000Base-T modes, 2500Base-T. Using the BIOS setup program or a user program, both
Ethernet channels can be disabled independently in order to free up system resources.

Ethernet Link Status LEDs
The green
“Link” (line) LED is on when a line is connected.
The green
“Act” (network activity) LED is on when the computer is receiving or sending packets
through the RJ45 connector.
3.2.3.3 DVI-I connector
The DVI-I connector on the front panel of the CPC505 (see Figure 3-5) is intended to connect an
analog VGA monitor (2048x1536@75Hz) or a digital DVI-D monitor (1920x1200@60Hz).
