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 7-slot
Enterprise Switch incorporates 60 Gbps of bandwidth
switching capacity. The backplane uses a dual,
star-wired interconnect scheme to connect each
payload slot to the switch fabric module.
The backplane of the CoreBuilder 9000 7-slot
Enterprise Switch is constructed from a non-blocking,
passive, and redundant design.
Five of these links (5 traces, each 2 Gbps) are
star-wired to the slot for the switch fabric module,
providing five primary high-speed links for each
interface module.
Switch Backplane Architecture
The backplane:
Supports one slot for a switch fabric module.
Supports automatic configuration detection.
Provides central clock distribution.
Backplane Connector Architecture
The backplane connector provides easy access to all
the services from the CoreBuilder 9000, including two
10-Mbps MLAN (Management LAN) channels, one
UART channel, a number of system clocks, and the
SCI (Serial Communication Interface) communications
channel.
The backplane connector consists of the:
Common signals bus — The common signals bus
consists of all the signals that are used for
system-wide functions. These include power
supply monitoring and control, backplane reset,
system clock signals, and an LED test signal.
Power delivery — The power delivery connector
provides the following voltage: +2.1V, +3.5V,
+5.2V, and +12V.
System communications channels — The
management system uses two types of busses to
communicate with other modules in the Switch:
Serial Communication Interface (SCI) — The
SCI bus serves as a communications path
between management modules.
