PCI 10/100 Fiber NIC

The 3Com 3CR990B-FX-97 is a 32-bit, 33 MHz PCI network interface card that delivers 10/100 Mbps connectivity over SC multimode fiber. It includes an onboard ARM9 security processor for hardware encryption offload and supports remote wake-up from standby mode only.

Suited for legacy fiber uplinks

This card fits older servers or workstations with a 32-bit PCI slot that need a secure, managed fiber link up to 2,000 metres in full duplex. It is not for systems lacking a 5 V PCI slot, for gigabit or 10-gigabit requirements, or for wake-on-LAN from shutdown or sleep states.

Security and manageability bundle

The ARM9 processor offloads 168-bit 3DES, 56-bit DES, SHA-1 and MD5 with up to 75 security associations, while TCP segmentation and checksum offloads reduce host CPU load. SNMP manageability and the 3Com Managed PC Boot Agent enable remote deployment and monitoring.

Highlights

  • Secure network traffic with hardware 3DES and DES offload
  • Extend links to 2,000 m full-duplex over multimode fiber
  • Wake systems remotely from standby via Wake-on-LAN
  • Offload TCP segmentation and checksum tasks to ARM9 processor
  • Fit standard 32-bit 33 MHz PCI slots for broad compatibility

Questions about this item

Does my motherboard need a 32-bit 33 MHz PCI slot for this 3CR990B-FX-97 card?

Yes, the card uses a 32-bit, 33 MHz PCI bus interface and requires an available PCI slot that matches that specification.

Will the SC fiber connector on this 3Com card link to my existing 62.5 µm multimode patch cables?

Yes, the card supports both 50 µm/125 µm and 62.5 µm/125 µm multimode fiber at 1300 nm wavelength using the SC connector.

How can I verify the ARM9 security processor is offloading 3DES encryption after I install the card?

Check the adapter statistics or SNMP management console for active security associations; the card supports up to 75 simultaneous associations with 168-bit 3DES offload.
