## Standards

- IEEE 802.1p: Priority Queuing (traffic prioritizing) and Quality of Service levels
- IEEE 802.1Q: Virtual LAN identification
- IEEE 802.3ab: Gigabit Ethernet over copper
- IEEE 802.3ac: Tagging
- IEEE 802.3ad: Link Aggregation (static mode is supported on indicated Intel adapters)
- IEEE 802.3u: Fast Ethernet
- IEEE 802.3x: Flow Control
- IEEE 802.3z: Gigabit Ethernet over optical fiber
- ACPI: Advanced Configuration and Power Management
- PCI: system bus specification: 32/64-bit, 33/66 Mhz (any combination, unless otherwise noted)
- PCI-X: system bus specification: 64-bit, 66/100/133 Mhz (any combination)

More information on IEEE 802 standards available at http://www.ieee802.org.

IEEE 802.3ac VLANs:

VLANs require VLAN capable switches either implicit (switch only) or explicit (IEEE 802.3ac). IEEE 802.3ac VLANs allow multiple VLANs per adapter or team since both the switch and adapter use a tag in the packet header to sort VLANs.

All PRO/1000 server adapters fully support IEEE 802.3ac VLANs when attached to an explicit VLAN enabled switch.

## Cabling

- 1000Base-SX on 850 nanometer optical fiber:

  - Utilizing 50 micron multimode, length is 550 meters max.

  - Utilizing 62.5 micron multimode, length is 275 meters max.

- 1000Base-LX on 1310 nanometer optical fiber:

  - Utilizing 50 micron multimode, length is 550 meters max.

  - Utilizing 62.5 micron multimode, length is 550 meters max.

  - Utilizing 9 micron single mode, length is 10 Km max.

- 1000BaseT on Category 4, or Category 5 wiring, twisted 4-pair copper.

  - Length is 100 meters max.

  - Category 3 wiring supports only 10Mbps.

## Ethernet MAC Addresses

### Single-Port Adapters

The Ethernet address is printed on the identification sticker on the front of the card.

### Dual-Port Adapters

There are two types of dual port adapters: a 32-bit adapter with part numbers 715191-00x or 751110-00x, and a 32/64-bit adapter with part numbers A28276-00x. On both types, the adapter's 12-digit, hexadecimal Ethernet address is printed on a sticker placed on the adapter, or can be found in the system's BIOS setup. The Ethernet address is sometimes called the node address or the MAC address.

For 32-bit dual port adapters, the Ethernet address printed on the identification sticker refers to the port closest to the PCI slot. Add 1 to the printed address to find the address of the 2nd port. For example, if the Ethernet address on the sticker reads xxxxxxxxxx77, then the address of the 2nd port (the one farthest from the slot) would be xxxxxxxxxx78.

For 32/64-bit dual port adapters, the Ethernet address printed on the identification sticker refers to the port farthest from the slot. Add 1 to the printed address to find the address of the 2nd port. For example, if the Ethernet address on the sticker reads xxxxxxxxxx77, then the address of the 2nd port (the one closest to the PCI slot) would be xxxxxxxxxx78.

### Integrated Adapters

On a system with the LAN integrated on the motherboard, the identification sticker is usually located on the motherboard near the network connector.
