In this section, information on the available token-ring adapter is given.
5.1.1.1 PCI IBM Token-Ring Adapter (# 2920)
The IBM PCI Token-Ring Adapter is a high performance 32-bit bus master
card designed to operate on selected RS/6000 models that incorporate the
PCI bus interface. The following is a list of attributes for this card:
• Enhanced system interface for higher throughput and lower system
utilization, coupled with RJ-45 and DB9 connectors
• Handles LAN environment requirements of today’s servers and high-end
workstations running I/O intensive applications on the network
• Operates at either 16 Mbps or 4 Mbps over unshielded twisted pair (UTP)
or shielded twisted pair (STP)
• Automatic ring-speed detection
• External status LEDs providing visual indication of adapter and ring status
