Introduction
1-2
¥ The 2E43-51 and 2E43-51R SmartSwitches, which are 48 port MicroLAN
Ethernet switches (4 MicroLANs of 12 ports each, via four RJ21 Telco
connectors) with 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 one additional slot for a High
Speed Interface Module (HSIM) which can provide FDDI, ATM, Gigabit
Ethernet, or WAN connectivity depending on the type of HSIM installed. The
only difference between the two devices is that the 2E43-51 supports a single
power supply, and the 2E43-51R supports dual, redundant power supplies.
¥ The 2H23-50R SmartSwitch is a 48 port MicroLAN 10/100 Mbps Ethernet
switch (4 separately repeated MicroLANs of 12 ports each, via four RJ21 Telco
connectors). The 2H23-50R also provides two FEPIM slots for uplinks, and
features redundant internal power supplies.
¥ The 2H33-37R SmartSwitch is a 36 port MicroLAN 10/100 Mbps Ethernet
switch (3 separately repeated MicroLANs of 12 ports each, via RJ21 Telco
connectors). A single HSIM slot is also provided, as are redundant internal
power supplies.
¥ The 2E48-27 and 2E48-27R SmartSwitches, which have a total of 27 ports
consisting of 24 built-in front panel 10Base-FL multimode Þber ST ports, 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 one additional slot for a High Speed Interface Module
(HSIM) which can provide FDDI, ATM, Gigabit Ethernet, or WAN
connectivity depending on the type of HSIM installed. The only difference
between the two devices is that the 2E48-27 supports a single power supply,
and the 2E48-27R supports dual, redundant power supplies.
¥ The 2E49-27 and 2E49-27R SmartSwitches, which have a total of 27 ports
consisting of 24 built-in front panel 10Base-FL single mode Þber ST ports, 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 one additional slot for a High Speed Interface Module
(HSIM) which can provide FDDI, ATM, Gigabit Ethernet, or WAN
connectivity depending on the type of HSIM installed. The only difference
between the two devices is that the 2E49-27 supports a single power supply,
and the 2E49-27R supports dual, redundant power supplies.
¥ The 2H252-25R SmartSwitch, which provides 24 10/100 Ethernet ports via
RJ45 connectors, as well as a VHSIM slot, which can accept any of CabletronÕs
HSIMs or the VHSIM-G6 Gigabit Ethernet High Speed Interface Module.
¥ The 2E253-49R SmartSwitch, which provides 48 Ethernet ports via 4 RJ21 Telco
connectors, redundant internal power supplies, and a single VHSIM slot.
¥ The 2H22-08R SmartSwitch, which has a total of eight ports consisting of six
built-in front panel 10/100BaseTX RJ45 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 2H22-08R supports dual, redundant power supplies.
