Migration Tower PCI Hardware

#2720/#9720 PCI WAN/Twinaxial IOA

This combined twinaxial/communication adapter supports 28 active twinaxial addresses. It
ships with a cable and a 4-port expansion box, with each port supporting seven attached
addresses. When the attached display supports address sharing, a maximum of 112 shared
sessions are supported. It also supports a single communications line. See "#9720 Base PCI
WAN/Twinaxial IOA" on page 100 for a discussion of the communications capabilities of this
adapter. When the attached display supports address sharing, a maximum of 112 shared
sessions are supported.
The #9720 is supported for migration only.

#2721/#9721 PCI Two-Line WAN IOA

The #2721/#9721 supports up to two multiple protocol communications ports and is
supported for migration only.

#2722 PCI Twinaxial Workstation IOA

The #2722 is an 8-port twinaxial workstation IOA with a 20-foot attachment cable for
attaching up to 40 5250-type displays and printers. Each port supports seven attached
addresses. This allows up to 56 attached addresses of which only 40 can be active. When
the attached display supports address sharing, a maximum of 120 shared sessions are
supported. The #2722 is specified when additional PCI twinaxial workstations controllers are
required.

#2723/#9723 PCI Ethernet IOA (10 Mbps)

This feature provides a single attachment to one Carrier Sense Multiple Access/Collision
Detect Local Area Network. It consists of an adapter card and internal code that supplies
Ethernet Version 2 and IEEE 802.3 Media Access Control (MAC), plus 802.2 Logical Link
Control (LLC) functions. The Ethernet/IEEE 802.3 IOA is capable of operating in half or full
duplex mode. RJ-45 cabling for 10 Mbps must be CAT-3 or CAT-5. If CAT 5 is used, it must meet
or exceed Industry Standard EIA/TIA T568A or T568B.
It has an RJ-45 connector and a 15-pin D-shell connector for attachment of
customer-supplied cabling. A vendor AUI Ethernet cable or RJ-45 twisted-pair cable must be
ordered separately.
