Welcome to the SPECTRUM Element Manager SmartSwitch 2000 UserÕs Guide.
We have designed this guide to serve as a simple reference for using SPECTRUM
Element Manager for the SmartSwitch 2000 family of devices.
The SmartSwitch 2000 product family consists of several models of standalone
high-speed network devices. By default, these devices perform traditional
switching (or bridging); each can also be conÞgured to perform prestandard IEEE
802.1Q VLAN switching (a.k.a Òport-based VLANÓ switching) or CabletronÕs
SecureFast switching (activated via Local Management).
The SmartSwitch 2000 family of devices includes:
¥ The 2E42-27 and 2E42-27R SmartSwitches, which have a total of 27 ports
consisting of 24 built-in front panel RJ45 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
2E42-27 supports a single power supply, and the 2E42-27R supports dual,
redundant power supplies.
¥ The 2E43-27 and 2E43-27R SmartSwitches, which have a total of 27 ports
consisting of two RJ21 Connectors (which provide 24 switched Ethernet
connections), 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 2E43-27 supports a single
power supply, and the 2E43-27R supports dual, redundant power supplies.
