Quad-port Gigabit adapter for PCI-X servers

The Intel PWLA8494GT provides four RJ-45 ports operating at 10, 100 or 1000 Mbps over a 32 or 64-bit PCI-X 1.0 or PCI 2.2 bus. It targets administrators who need to connect a single server to several network segments while using only one expansion slot.

Sustained throughput on all four ports

On-board memory of 256 KB helps buffer traffic when multiple gigabit links are active simultaneously, reducing packet loss during prolonged transfers. Teaming support lets the four ports combine bandwidth or provide failover without relying on extra adapters.

Operating limits and power profile

The card is rated for continuous operation from 0 °C to 55 °C at up to 85 % relative humidity and runs on a 3.3 volt bus supply. No Wake-on-LAN function is present, so power draw remains constant regardless of system sleep state.

Questions about this item

How much heat does the PWLA8494GT produce when running all day at full Gigabit speed?

The card is rated for an operating temperature range of 0°C to 55°C with up to 85% humidity at 55°C, so it stays within spec under continuous load.

Does the PWLA8494GT need a PCI-X 1.0 slot with 3.3 V signalling, or will it work in a standard 32-bit 5 V PCI slot?

It supports both 3.3 V 64-bit PCI-X 1.0 and 32/64-bit PCI 2.2 buses, so it fits either a PCI-X 1.0 slot or a conventional PCI 2.2 slot.

Will the four RJ45 ports on the PWLA8494GT negotiate down to 10 Mbps if I connect them to legacy 10BASE-T switches?

Yes, the adapter complies with IEEE 802.3ab and handles 10/100/1000 Mbps speeds, so each port will auto-negotiate to 10 Mbps when linked to older 10BASE-T equipment.
