Remote Wake-Up Support 17
Support for Full-Duplex/Dedicated Token Ring
Full-duplex/Dedicated Token Ring (DTR) is an enhancement
to the IEEE 802.5 standard that allows a token ring switch
port to be dedicated to a station.
In full-duplex mode, a station can simultaneously transmit
and receive independent data streams for potential data
throughput of 32 Mbps. The 3C359B NIC can operate in
full-duplex mode when attached to a DTR switch.
Remote Wake-Up Support
The 3C359B NIC supports the capability to remotely
wake-up a PC from a power-saving “sleep” state. The NIC
monitors the network for certain kinds of packets (such as
a Magic Packet, a directed packet, or packets that
incorporate a wake-up pattern) while the PC is asleep.
When the NIC detects a wake-up packet, it wakes up
the PC. Once the PC is awake, you can perform software
upgrades, backups, and other management tasks from a
central location.
“Remote Wake-Up” is equivalent to other popular
“wake-up” terms that are currently in use (for example,
“Wake On LAN”).
The 3C359B NIC’s Remote Wake-Up support conforms to
the Advanced Configuration and Power Interface (ACPI)
specification and applies only to PCs that implement either
the PCI Bus Power Management Interface Specification
(versions 1.0 or 1.1) or a Remote Wake-Up connector on
the PC motherboard. The connector allows a 3-wire cable
to be connected between the NIC and the motherboard.
See your PC system documentation to determine which
mechanism is supported.
If your PC supports the 3-wire cable, then install the cable
supplied with the 3C359B NIC after inserting the NIC into
the appropriate slot. (See “Connecting the Remote
Wake-Up Cable” in Chapter 2.)
If the PC has PCI bus power management, then insert the
NIC without installing the cable. No cable is required.
