PhaserShare Series B Network Interfaces
PhaserShare Series B Token Ring card
The PhaserShare Series B Token Ring port conforms to the IEEE 802.5 standard.
With the PhaserShare Series B Token Ring card, you can connect the printer directly
to a Token Ring network using shielded twisted pair (STP; IBM Type 1) or
unshielded twisted pair (UTP; IBM Type 3) cables. Contact your dealer to obtain
adapters and cables.

To fully comply with EMI specifications, the use of shielded or screened cables may
be required. “Shielded” describes IBM-defined cables used with the DB-9
connector. “Screened” describes cables that are electrically similar to Category 4
UTP, but with an added shield or screen.
When a PhaserShare Series B card is purchased initially with the printer, it is
installed at the factory. When a PhaserShare Series B card is purchased later as an
upgrade kit, follow the installation instructions that are shipped with the card.
When a PhaserShare Series B Token Ring card is installed in the printer, the printer’s
built-in Ethernet connector is disabled.

To avoid damaging the network interface, turn off the printer before making any
Token Ring connections.
