GM1 - Quad Gigabit Ethernet Rear I/O Card (Product Discontinued)

The GM1 is a mezzanine card which is plugged onto CompactPCI Serial CPU boards to implement four Ethernet interfaces on the backplane.

The CompactPCI Serial standard defines up to eight Ethernet interfaces which can be connected in a star or in full mesh architecture via the backplane. The GM1 is used to implement four Gigabit Ethernet interfaces which are led to the backplane via CompactPCI Serial connector P6. All four interfaces are controlled by one Ethernet controller which supports the IEEE 802.3xstandard.

In addition, the GM1 offers the possibility to plug a microSD card.

The board is screened for operation in the extended temperature range of -40 to +85°C.
