4-Port Gigabit Ethernet Switch PCI-104 Card   Support 32 bit PCI-104 bus 4 ports RJ45 Gigabit Ethernet Switch IEEE 802.3 10Base-T/100Base-Tx/ 1000Base-T compatible Full or half duplex at 10/100/1000 Mbps IEEE 802.3u Auto-Negotiation supported QoS supported 1.5KV Hi-pot isolation protection

The JetCard 2154G is a flexible and high performance four-port Ethernet switch card in PCI-104 format. The PCI-104 bus of JetCard 2154G supports both +3.3V and +5V slot. The easy-to-install drivers that come with JetCard make it easier for you to set up your complex system. And with its 1.5KV Hipot isolation protection, and overload current/voltage protection, JetCard 2154G is ideal for industrial applications in severe environments and is your best choice for embedded networking solution.

The JetCard 2154G uses Marvell 88E6161 chip to provide 4 Gigabit Ethernet ports. Each Ethernet port in the JetCard offers IEEE 802.3 compliant Ethernet data transmission with auto MDI/MDI-X and autonegotiation, and 1000 Base-T with 10K Jumbo frames.

Jumbo frames: Jumbo frames are Ethernet frames with more than 1,500 bytes of payload (MTU) and the JetCard 2154G can support up to 10Kbyte of payload. Jumbo frames can help performance by reducing the load on the CPU (by requiring fewer headers to be processed for the same amount of payload data).

Auto MDI/MDI-X: The JetCard automatically determine whether or not it needs to interchange cable sense between pairs so that an external crossover cable is not required. If the JetCard interoperate with a device that cannot automatically correct for crossover, the JetCard makes the necessary adjustment prior to commencing Auto-Negotiation.

Flow control: The JetCard supports back pressure and pause frame-based flow control schemes to ensure zero packet loss under temporary traffic congestion.

QoS (Quality of Service): QoS for networks is an industry-wide set of standards and mechanisms for ensuring high-quality performance for critical applications. The JetCard provides the shared memory-based QoS switch architecture. Packets are directed into one of four traffic class queues based upon Port, IEEE 802.1p, IPv4’s TOS or Diff-Serv, or IPv6’s Traffic Class.
