	LEDs
	Table 1-1. Switch and Port LEDs
Switch LEDs	State	Meaning
Power	On	The switch is receiving power.
(green)	Off	The switch is NOT receiving power.
Fault	Off	The normal state; indicates that there are no fault conditions on the switch.
(orange)	Blinking†	A fault has occurred on the switch, one of the switch ports, or the fan. The Status LED
		for the component with the fault will blink simultaneously.
	On	On briefly after the switch is powered on or reset, at the beginning of switch self test.
		If this LED is on for a prolonged time, the switch has encountered a fatal hardware
		failure, or has failed its self test. See chapter 3, “Troubleshooting” for more information.
Self Test	Off	The normal operational state; the switch is not undergoing self test.
(green)	On	The switch self test and initialization are in progress after you have power cycled or
		reset the switch. The switch is not operational until this LED goes off. The Self Test LED
		also comes on briefly when you “hot swap” a module into the switch; the module is self
		tested when it is hot swapped.
	Blinking†	A component of the switch has failed its self test. The status LED for that component,
		for example an RJ-45 port, and the switch Fault LED will blink simultaneously.
Fan Status	On	The cooling fan is operating normally.
(green)	Blinking†	The cooling fan has failed. The switch Fault LED will be blinking simultaneously.
Link	On	Indicates the port is enabled and receiving a link indication from the connected device.
	Off	One of these conditions exists:
		• no active network cable is connected to the port
		• the port is not receiving link beat or sufficient light
		• the port has been disabled through the switch console, the web browser interface,
		or SNMP management software.
	Blinking	If the LED is blinking simultaneously with the Fault LED, the corresponding port has
		failed its self test.
		The LED can blink by itself (no Fault LED blinking) for the module ports. This occurs
		when a module is installed and the switch has not yet been reset. Modules can be
		installed in the slots while the switch is powered on, but the switch must be reset to
		initialize the module and make it operational.
Act (green)	On	Indicates network activity on the port. Note that the LED will flicker as network traffic
		is received and transmitted through the port.

† The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.

Console Port

This port is used to connect a console to the switch by using the serial cable supplied with the switch. This connection is described under “Connect a Console to the Switch” in chapter 2, “Installing the Switches”. The console can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.

Reset Button

This button is used to reset the switch while it is powered on. This action clears any temporary error conditions that may have occurred and executes the switch self test. Press the Reset button also after installing any modules while the switch is powered on. After installing the module, the switch must be reset to initialize the module and make it operational.

This button also resets all network activity counters to zero. The counters are displayed in the SMC6624M console interface, the web browser interface, and through SNMP network management applications, such as EliteView.

Clear Button

This button is used for these purposes:

■Deleting Passwords - When pressed by itself for at least one second, the button deletes any switch console access passwords that you may have configured. Use this feature if you have misplaced the password and need console access.

This button is provided for your convenience, but its presence means that if you are concerned with the security of the switch configuration and operation, you should make sure the switch is installed in a secure location, such as a locked wiring closet.

■Restoring Factory Default Configuration - When pressed with the Reset button in a specific pattern, any configuration changes you may have made through the switch console, the web browser interface, and SNMP management are removed, and the factory default configuration is restored to the switch. For the specific method to restore the factory default configuration, see “Restoring the Factory Default Configuration” in chapter 3, “Troubleshooting” of this manual.

Switch Features

Switch Features

The features of the SMC6624M includes:

■24 autosensing 10/100Base-TX RJ-45 ports with Auto MDI/MDI-X.

■two slots for installing supported gigabit or 100Base-FX modules.

■plug-and-play networking—all ports are enabled—just connect the network cables to active network devices and your switched network is operational.

■Auto MDI/MDI-X on all 10/100 twisted-pair ports, and IEEE 802.3ab Auto MDI /MDI-X on all 100/1000 twisted-pair ports, meaning that all connections can be made using straight-through twisted-pair cables.

Cross-over cables are not required, although they will also work. The pin operation of each port is automatically adjusted for the attached device: if the switch detects that another switch or hub is connected to the port, it configures the port as MDI; if the switch detects that an end-node device is connected to the port, it configures the port as MDI-X.

■automatic learning of the network addresses in each switch’s 4096address forwarding table, (with configurable address aging value).

■automatically negotiated full-duplex operation for the fixed 10/100 RJ-45 ports when connected to other auto-negotiating devices — the module ports always operate at full duplex.

The SMC6624M also includes these network management features:

■easy management of the switch through several available interfaces:

•web browser interface—an easy to use built-in graphical interface that can be accessed from common web browsers.

•console interface—a full featured, easy to use, VT-100 terminal interface that is especially good for out-of-band switch management or for telnet access to the switch.

•EliteView—an SNMP-based, graphical network management tool that you can use to manage your entire network.

■support for the Spanning Tree Protocol to eliminate network loops.

■support for up to 30 IEEE 802.1Q-compliant VLANs so you can divide the attached end nodes into logical groupings that fit your business needs.

■support for many advanced features to enhance network performance and network traffic control—described in the Management Guide that came with your SMC6624M.

■download of new code for product enhancements or bug fixes.

Switch Operation Overview

Switch Operation Overview

Address Table Operation

Address Learning. As devices are connected to the switch ports, either directly or through hubs or other switches, the MAC addresses of those devices are learned automatically and stored in the 4096-entry address table featured by the SMC6624M. The switch also identifies the number of the port on which each address is learned so they know the network location of each connected device.

Forwarding, Filtering, Flooding. When the switch receives a packet, it determines the destination address and looks for the address in the address table. Based on the port location of that address, the switch then determines whether to forward, filter-out, or flood the packet.

■forward - if the destination address is on a different port than the one on which the packet was received, the packet is forwarded to the destination port and on to the destination device.

■filter out - if the destination address is on the same port as the one on which the packet was received, the packet is filtered out. The switch thereby isolates local traffic so the rest of the network connected to the switch does not lose bandwidth dealing with unnecessary traffic.

■flood - whenever a new destination address is found in a packet received on a switch port, the destination address will not yet be in the switch’s address table and the switch cannot know whether to forward or filter out the packet. In this case, it sends the packet to all the other switch ports. This is referred to as “flooding”. When the destination device receives the packet, and it replies, the switch learns the new address from the reply packet. Then, all future packets destined for that address are forwarded or filtered out appropriately.

Note: Usually, multicast and broadcast packets are flooded, although configuration of sofware features influence that behavior.

Switch Operation Overview

Network Moves and Changes. When a PC, server, printer, or other network device is moved in the network, and becomes connected to a different switch port, the SMC6624M automatically recognizes the change and updates the address table with the new port location of the device. Communication with the device is automatically maintained, without any address table manipulation being required by the network administrator.

Effect of VLANs

If you configure multiple virtual LANs (VLANs) on the switch, each VLAN behaves as a “logical switch” containing the switch ports that you assign to it. Each logical switch behaves as an isolated broadcast domain, just as if it were a separate physical switch. The forward, filter, and flood behavior described for the physical switch above, operates the same for each of the logical switches defined by the VLANs: packets are forwarded or flooded only to the ports that are within a given VLAN. Just as for separate isolated physical switches, there is no communication between ports that are in separate VLANs unless the VLANs are connected by an external router.

For more information on configuring VLANs and their behavior, see the

Management Guide that came with your switch.

Installation Procedures

Summary

Follow these easy steps to install your switch. The rest of this chapter provides details on these steps.

1.Prepare the installation site (page 2-4). Make sure that the physical environment into which you will be installing the switch is properly prepared, including having the correct network cabling ready to connect to the switch and having an appropriate location for the switch. Please see page 2-3 for some installation precautions.

2.Install modules (optional—page 2-6). The switches have two slots for installing any of the supported 1 Gbps (gigabit) or 100 Mbps modules. Depending on where you will install the switch, it may be easier to install the modules first.

3.Verify that the switch passes self test (page 2-7). This is a simple process of plugging the switch into a power source and observing that the LEDs on the switch’s front panel indicate correct switch operation.

4.Mount the switch (page 2-9). The switch can be mounted in a 19-inch telco rack, in an equipment cabinet, on a wall, or on a horizontal surface. The included mounting brackets allow mounting the switch in a variety of locations and orientations.

5.Connect power to the switch (page 2-13). Once the switch is mounted, plug it in to the nearby main power source.

6.Connect the network devices (page 2-14). Using the appropriate network cables, connect the network devices to the switch ports.

7.Connect a console to the switch (optional—page 2-15). You may wish to modify the switch’s configuration, for example, to configure an IP address so it can be managed using a web browser, from an SNMP network management station, or through a Telnet session. Configuration changes can be made easily by using the included console cable to connect a PC to the switch’s console port.

At this point, your switch is fully installed. See the rest of this chapter if you need more detailed information on any of these installation steps.
