Introduction
¥ The
2H28-08R
SmartSwitch, which has a total of eight ports consisting of six
built-in front panel 100BaseFX multimode Þber SC ports and two front panel
slots for optional Fast Ethernet Port Interface Modules (FEPIMs) to support an
uplink to 100 Mbps Ethernet backbones or a high speed connection to a local
server. The 2H28-08R supports dual, redundant power supplies.
¥ The
2H253-25R
SmartSwitch is a 10/100 Fast Ethernet switch, providing 24
100BaseTX ports via dual RJ21 connectors, and a VHSIM slot. The 2H253-25R
also includes redundant internal power supplies.
¥ The
2H258-17R
SmartSwitch features 16 100BaseFX MMF (via MT-RJ
connectors) ports, and a single VHSIM slot. The 2H258-17R also includes
redundant internal power supplies.
¥ The
2M46-04R
SmartSwitch provides two front panel slots for optional Fast
Ethernet Port Interface Modules (FEPIMs) to support an uplink to 100 Mbps
Ethernet backbones or a high speed connection to a local server, and two slots
for High Speed Interface Modules (HSIMs) which can provide FDDI, ATM,
Gigabit Ethernet, or WAN connectivity depending on the type of HSIMs
installed. The 2M46-04R supports dual, redundant power supplies.
Several Fast Ethernet Port Interface Modules (FEPIMs) are available for use with
the various SmartSwitch 2000 models:
¥ the
FE-100FX
, which provides one multi-mode Þber port via an SC connector;
¥ the
FE-100TX
, with one Category 5 UTP RJ45 connector;
¥ the
FE-100F3
, with one single-mode Þber port via an SC connector;
¥ and the
FE-100S1
,
S3
, and
S5
, which provide one multi-mode Þber,
single-mode Þber, or long reach single-mode Þber SONET/SDH port, all via
SC connectors.
Two types of High Speed Interface Modules (HSIMs) are available for use with
the various SmartSwitch 2000 models. Each HSIM provides frame translation
between ATM, FDDI, WAN, Gigabit Ethernet, and Ethernet through an on-board
Intel i960 processor:
¥ The
HSIM-F6
is an FDDI/Ethernet Translator, which can act as a Single
Attached Station (SAS) or Dual Attached Station (DAS) on an external FDDI
ring. CabletronÕs FDDI Port Interface Modules (FPIMs) provide a wide range
of media connectivity to the ring. The HSIM-F6 also has full-duplex capability,
allowing for a 200 Mbps connection to another HSIM-F6.
¥ The
HSIM-A6DP
is an Asynchronous Transfer Mode (ATM) HSIM, which
provides an ATM uplink via two media-conÞgurable ATM Port Interface
Modules (APIMs). The dual APIM design allows for a redundant connection
to the uplink, so that if the primary interface fails, the secondary interface will
automatically take over. The HSIM-A6DP acts as an ATM Forum LAN
Emulation Client (LEC) so that it can transfer data between devices on an
802.X LAN supported by the SmartSwitch 2000 and ATM-connected end
stations (or other 802.X end stations) across a high speed ATM Link. The
HSIM-A6DP adheres to the ATM Forum-approved LAN Emulation (LANE)
