Gigabit Ethernet SmartSwitch
Modules
The Gigabit Ethernet SmartSwitch Modules
(9G426-02, 9G421-02, and 9G429-02) are single
slot devices that connect to the INB backplane to
integrate connectivity to ATM, FDDI, and Fast
Ethernet. They feature traditional switching
services as well as Cabletron’s SecureFast Virtual
Networking, embedded Virtual Routing, optional
RMON support, and Broadcast Storm Protection
on every port. The devices provide two front panel
slots that can accommodate SC connectors
offering MMF and SMF connection options. The
9G421-02 and 9G429-02 devices support the
IEEE draft 802.3 specification for Gigabit
Ethernet.
Token Ring MicroLAN Switch
Modules
The TR MicroLAN Switch Modules (9T122-08 and
9T122-24) provide connectivity to two TR
networks through the FDDI backplane in the
chassis. The TR MicroLAN Switch Module’s single
24-port Token Ring, or two 12-port Token Rings
use standard RJ-45 connectors supporting either
Unshielded Twisted Pair (UTP) or Shielded
Twisted Pair (STP) lobe wiring. The rings
interconnect across the chassis’s FNB, a dual 100
Mbps FDDI backplane, and can be configured for
FNB-1 or FNB-2.
The 9T125-08 and 9T125-24 provide connectivity
for two individual Token Ring networks. The rings
interconnect across the FNB, and can be
configured for FNB-1 or FNB-2.
Token Ring SmartSwitch Module
Designed specifically for collapsed Token Ring
backbones, the 9T425-16 and 9T428-16 Token
Ring SmartSwitches occupy two slots, and the
9T427-16 occupies one slot in the chassis. The
9T428-16 has 16 switched multimode fiber ports
supported by ST connectors. The 9T425-16 and
9T427-16 are equipped with 16 copper RJ-45
Dedicated Token Ring (DTR) lobe/station ports,
also known as concentrator or C-ports.
These modules are considered a “hard card,” with
all switching functions performed by the Fast
Packet Switch (FPS Application Specific
Integrated Circuits ASICs). The TR SmartSwitch
Modules attach to the INB 2 backplane and have
System Management Bus -1 (SMB-1) and SMB-10
connections for system management.
