2.1

Power Supply

The G211 is supplied with a primary +12V voltage via the CompactPCI Serial connector P1.

2.2

Ethernet Interfaces

The G211 has four Gigabit Ethernet interfaces controlled by the Intel 82580 Dual/

Quad Gigabit Ethernet Controller. All channels support 10/100/1000Base-T physical layers, and half-duplex and full-duplex operation complying with

IEEE802.3x. Each of the four channels reach a performance of 1 Gbit/s read and/or write, even when all four interfaces are used simultaneously.

The unique MAC address for every interface is set at the factory and should not be changed. Any attempt to change this address may create node or bus contention and thereby render the board inoperable. The MAC addresses on G211 are:

• Interface X1:

0x 00 C0 3A 9D 0x xx

• Interface X2:

0x 00 C0 3A 9D 1x xx

• Interface X3:

0x 00 C0 3A 9D 2x xx

• Interface X4:

0x 00 C0 3A 9D 3x xx where "00 C0 3A" is the MEN vendor code, "9D" is the MEN product code. The last four digits depend on the interface and the serial number of the product. The serial number is added to the offset, for example for X2:

• Serial number 0042:

0x xx xx = 0x1000 + 0x002A = 0x 10 2A.

(See

Chapter 3.2 Finding out the Product’s Article Number, Revision and Serial

Number on page 21

.)

2.2.1

Connection

The G211 is available in two standard versions: one provides four standard RJ45 connectors and one four 8-pin M12 connectors at the front panel.

The pin assignments correspond to the Ethernet specification IEEE802.3.

CompactPCI Serial Interface

The G211 uses up to four PCI Express lanes at the backplane according to the

CompactPCI Serial specification (PICMG CPCI-S.0, proposed standard under development).

Connector type of P1:

• 72-pin Airmax VS 4 pair, right angle header, 6 IMLA with end walls

See the following table for the pin assignment of the P1 connector:
