EME Network Management Functions

The EME provides the following management and
control capabilities:
Configurations — When you are logged in using
I
the Administer password, you can configure the
EME and monitor the chassis environment.
Inventory — The EME provides a complete
I
inventory of Switch contents, including fans and
power supplies. The inventory lists current
software revisions for all installed modules. The
inventory system also supports a scratchpad
feature so that you can add custom information to
the EME display.
Power Management — With EME commands,
I
you can manage how the Switch reacts to low
power situations. The Switch can also provide
fault-tolerant power, which protects the Switch
against power supply failures.
SNMP Support — SNMP (Simple Network
I
Management Protocol) is a protocol that the
Internet Engineering Task Force defined. The EME
acts as an agent in an SNMP-managed
environment. The agent responds to SNMP
requests and generates SNMP traps.
Telnet Support — With the EME
I
command, you can connect an EME to any other
Telnet device. The EME also supports incoming
Telnet sessions so that you can manage an EME
from a workstation with Telnet support or from
another EME.

In-Band and Out-of-Band Download — The
I
EME provides both in-band and out-of-band
downloads. In-band download uses TFTP (Trivial
File Transfer Protocol) through a network
connection. Out-of-band download uses
XMODEM software and the RS-232 serial port on
the front panel of the EME. The EME allows you to
download to multiple modules using a single
command.
Web Management Support — You can monitor
I
and manage the EME through the Switch 4007R
Web Management suite of applications.
3Com Network Supervisor Support — You can
I
also monitor and manage the EME through the
3Com Network Supervisor.
The backplane of the Switch 4007R incorporates 240
Gbps of bandwidth capacity in a passive and
redundant design. The backplane uses a dual,
star-wired interconnect scheme to connect each
payload slot to the primary and backup switch fabric
module.
The backplane of the Switch 4007R 8-slot Enterprise
Switch is constructed from a non-blocking, passive,
fully redundant design.
Five of these links (5 traces, each 2 Gbps) are
star-wired to each of the slots for the switch fabric
modules, providing five primary and five redundant
high-speed links for each interface module.
