Switch Backplane Architecture 35
■
Power Management — With EME commands,
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
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
telnet
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
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
and manage the EME through the
CoreBuilder 9000 Web Management suite of
applications.
■
Transcend Network Control Services
Support
— You can also monitor and manage the
EME through the 3Com Transcend Network
Control Services.
Switch Backplane Architecture
The backplane of the CoreBuilder 9000 16-slot
Enterprise Switch incorporates 280 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 CoreBuilder 9000 16-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.
The backplane:
■
Supports two slots for switch fabric modules.
■
Supports automatic configuration detection.
■
Provides central clock distribution.
