FCC - Class A

This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause interference to radio
communications. It has been tested and found to comply with the limits for a Class A
computing device pursuant to Subpart B of Part 15 of FCC Rules, which are designed to provide
reasonable protection against such interference when operated in a commercial environment.
Operation of this equipment in a residential area is likely to cause interference, in which case the
user, at his own expense, will be required to take whatever measures may be required to correct
the interference. You are cautioned that changes or modifications not expressly approved by the
party responsible for compliance could void your authority to operate the equipment.

You may use unshielded twisted-pair (UTP) cable for RJ-45 connections—Category 3 or greater
for 10 Mbps connections, Category 5 for 100 Mbps connections and Category 5, 5e or 6 for
1000 Mbps connections. Use 50/125 or 62.5/125 micron multimode fiber optic cable, or 9/125
micron single-mode cable, for SFP transceiver connections.

War ning s: 1. Wear an anti-static wrist strap or take other suitable measures to prevent elec-

trostatic discharge when handling this equipment.

2. When connecting this switch to a power outlet, connect the field ground lead
on the tri-pole power plug to a valid earth ground line to prevent electrical
hazards.

Industry Canada - Class A

This digital apparatus does not exceed the Class A limits for radio noise emissions from digital
apparatus as set out in the interference-causing equipment standard entitled “Digital Apparatus,”

Overview

The SMC6824MPE Power over Ethernet switch contains 24 10BASE-T/
100BASE-TX RJ-45 ports and and two combination ports—10/100/
1000BASE-T ports that operate in combination with Small Form Factor
Pluggable (SFP) transceiver slots. An optional SFP stacking transceiver is
available for connecting up to eight units to a 1 Gbps stack backplane.

All the 10BASE-T/100BASE-TX ports on the switch support IEEE 802.3af
standard (802.3af) Power over Ethernet capabilities. Each port can detect
connected 802.3af-compliant network devices, such as IP phones or wireless
access points, and automatically supply the required DC power.

As well as its Power over Ethernet capabilities, the switch provides
comprehensive network management features, such as Spanning Tree
Protocol, multicast switching, virtual LANs, and Layer 2/3/4 CoS services
that provide reliability and consistent performance for your network traffic.

Switch Architecture

The SMC6824MPE switch employs a wire-speed, non-blocking switching
fabric. This permits simultaneous wire-speed transport of multiple packets at
low latency on all ports. The SMC6824MPE switch also features full-duplex
capability on all ports, which effectively doubles the bandwidth of each
connection.

The switch uses store-and-forward switching to ensure maximum data
integrity. With store-and-forward switching, the entire packet must be
received into a buffer and checked for validity before being forwarded. This
prevents errors from being propagated throughout the network.

The switch includes two Gigabit combination ports with RJ-45 connectors
and associated SFP slots. The optional SFP stacking transceiver enables up to
eight units to be connected together through a 1 Gbps stack backplane. The
switch stack can be managed from a connection to any port on the stack
using a single IP address.

Power over Ethernet Capability

The SMC6824MPE switch’s 24 front panel 10/100 Mbps ports support the
IEEE 802.3af Power over Ethernet (PoE) standard that enables DC power
to be supplied to attached devices using wires in the connecting Ethernet
cable. Any 802.3af-compliant device attached to a port can directly draw
power from the switch over the Ethernet cable without requiring its own
separate power source. This capability gives network administrators
centralized power control for devices such as IP phones and wireless access
points, which translates into greater network availability.

For each attached 802.3af-compliant device, the SMC6824MPE switch
automatically senses the load and dynamically supplies the required power.
The switch delivers power to a device using the two wire pairs in UTP or
STP cable that are not used for 10BASE-T/100BASE-TX connections. Each
port can provide up to 15.4 W of power at the standard -48 VDC voltage.
Independent overload and short-circuit protection for each port allows the
switch to automatically shut down a port’s power when limits are exceeded.

Network devices such as IP phones, wireless access points, and network
cameras, typically consume less than 10 W of power, so they are ideal for
Power over Ethernet applications.

Network Management Options

With a comprehensive arrangement of LEDs, the SMC6824MPE switch
provides “at a glance” monitoring of network and port status. The switch can
be managed over the network with a web browser or Telnet application, or
via a direct connection to the console port. The switch includes a built-in
network management agent that allows it to be managed in-band using
SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an RS-232 serial
port (DB-9 connector) on the front panel for out-of-band management. A
PC may be connected to this port
out-of-band via a

Description of Hardware

10/100BASE-T Ports

The SMC6824MPE switch base unit contains 24 10BASE-T/100BASE-TX
RJ-45 ports. All ports support automatic MDI/MDI-X operation, so you can
use straight-through cables for all network connections to PCs or servers, or
to other switches or hubs. (See “10/100BASE-TX Pin Assignments” on
page B-2.)

Each of these ports support auto-negotiation, so the optimum transmission
mode (half or full duplex), and data rate (10 or 100 Mbps) can be selected
automatically. If a device connected to one of these ports does not support
auto-negotiation, the communication mode of that port can be configured
manually.

Each port also supports IEEE 802.3x auto-negotiation of flow control, so
the switch can automatically prevent port buffers from becoming saturated.

1000BASE-T/SFP Ports

These are combination Gigabit RJ-45 ports with shared Small Form Factor
Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased
separately) is installed in a slot and has a valid link on the port, the associated
RJ-45 port is disabled.

The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation,
so you can use straight-through cables for all network connections to PCs or
servers, or to other switches or hubs. (See “1000BASE-T Pin Assignments”
on page B-4.)

Note: Neither the 1000BASE-T RJ-45 ports nor the SFP slots support PoE

capability.

Port and System Status LEDs

The SMC6824MPE switch base unit also includes a display panel for key
system and port indications that simplify installation and network
troubleshooting. The LEDs, which are located on the front panel for easy
viewing, are shown below and described in the following tables. The port
status LEDs have two display modes; Link and PoE. The Link mode displays
the link status and network activity on each port. The PoE mode displays the
PoE power status on each port. Use the Mode Link/PoE button (see “Mode
PoE/Link Button” on page 1-8) on the front panel to toggle between the
two display modes. The current mode is indicated by the Link/Act and PoE
system LEDs.
