Installing Modules
The process for installing both optional modules is the same. You cannot change the
position of the CPU module. The DES-5024 will not work unless the CPU module is
installed in the CPU slot.
You can purchase optional modules separately in order to meet the needs of your
network. The two optional modules available for the DES-5024 are: a 2-Port 100BASEFX (fiber optic) module and a 1-Port 1000BASE-SX (gigabit) module. As shown in
Figure 7, optional modules can only be installed in Slot 3. Nothing can be installed in slot
4. The procedure for installing modules is the same for all both modules.
Follow these steps to install an optional module:
1. Power the DES-5024 off before installing the optional module. The optional modules
are not hot swappable.
2. Remove the blank bracket, as shown in Figure 7, and set aside. Grasp the
thumbscrews on the sides of the blank bracket and turn counterclockwise to unscrew
them. You can also use a Phillips screwdriver to unscrew the blank bracket. Do not
discard the blank bracket. Put the blank bracket back in if you remove the optional
module.
3. Install the optional module by inserting it into the guide, see Figure 8, and sliding it in
until it stops. Press in firmly until you feel the optional module snap into place. The
optional module should be level and flush with the rest of the DES-5024. Never force,
twist or bend the module. The optional module slides in smoothly.
4. Gently push the thumbscrews in and turn clockwise to tighten. Do not over tighten
the thumbscrews.
5. Power the DES-5024 on after you have installed the optional module. The DES-5024
will auto detect the optional module.
6. Remove the dust cover from the transceiver and plug the cable in.
7. Check the LEDs to verify that there is a link and a proper connection at the port.
See the Troubleshooting section if the optional module is not working properly.

Connecting the DES-5024 to the
Network
This chapter covers the following:
• Cable Specifications
• Ports
• Connecting the DES-5024 to another DES-5024
• Connecting the DES-5024 to other switches and hubs
This section deals with making cables and connecting the DES-5024 to other devices. It
is extremely important that cables have the correct pin arrangement and that the proper
cables be used when connecting to servers, switches, hubs, workstations and other
devices.
3
Cable Specifications
Use the following guidelines when handling cables:
• Do not stretch or bend cables.
• Do not put copper cables near sources of electromagnetic interference. Fiber optic
cables are immune to electromagnetic interference.
• Do not create trip hazards by laying cables in aisles and walkways.
• Secure cables to the floor when routing in aisles or walkways.
Do not use telephone cable. Telephone cable does not support Ethernet or Fast Ethernet.
Copper Cable
In order for Ethernet or Fast Ethernet to work the wires must be arranged correctly inside
the RJ-45 connector. The most common problem on Ethernet or Fast Ethernet networks is
the cable. If you migrate from Ethernet to Fast Ethernet, make sure the cables are pinned
out properly.
There are two types of cables: straight through and crossover. Category 3, 4, or 5
UTP/STP cable has eight wires inside the sheath. The wires form four pairs. Straight
through cable has the same pin out, inside the RJ-45 connector, at both ends. Crossover
cable has a different pin arrangement at each end. Fast Ethernet does not tolerate
incorrect pin arrangements. You must use the correct pin arrangement in order for the
DES-5024 to work properly. See Figure 9 for an example of straight through and
crossover cable.
The type of cable you use depends on the speed of your network. A network running at
10 Mbps can use lower grade cable than a network running at 100 Mbps., Table 1: Cable
Specifications, shows the cable requirements for Ethernet and Fast Ethernet networks.

Ports
MDI-X Ports
MDI-X ports are crossover ports. The pin arrangement is the same as the arrangement in
a crossover cable. The advantage of MDI-X ports is that you can connect a device with
an MDI-II port without using a crossover cable. The steps for connecting the DES-5024
to 10 Mbps devices or 100 Mbps devices are the same. All the ports will auto negotiate
the proper speed and duplex mode. The DES-5024 has two full sized modules with 12
ports each and one half size optional module.
Follow these steps to connect cables to the DES-5024:
Check for the appropriate cable configuration for each device.
1. Plug one end of the cable into any of the MDI-X ports.
2. Plug the other end into the appropriate port on the other device.
3. Verify that the LED indicates connection at the proper speed and duplex mode.
Fiber Optic Ports
The DES-5024 supports 100BASE-FX and 1000BASE-SX. The ports are on modules
that you can install in the chassis. The chassis supports a 2-Port 100BASE-FX optional
module. The ports support full and half duplex at 100 Mbps. The ports do not support 10
Mbps.
A 1-Port 1000BASE-SX optional module is available. The 1-Port 1000BASE-SX
optional module only supports full duplex at 1000 Mbps. Contact D-Link, Inc. sales to
purchase any of the modules.
Refer to Chapter 3, Installing Optional Modules, for installation instructions. Refer to
Chapter 3, Cable Specifications, for information on cable types and connectors.
RS-232 Port
Follow these steps to connect the DES-5024 and another device:
1. Plug one end of the cable provided into the port.
2. Plug the other end into the PC.
3. Run HyperTerminal or a terminal emulation program using the settings given for
Local Console Management at the beginning of Chapter 5, Managing the DES-5024.

DES-5024 to DES-5024 Connection
Connect two DES-5024s together through one or more MDI-X ports. See the section on
Port Trunking in Chapter 5 for instructions on how to configure trunked ports.
Connecting the DES-5024 to other Switches
and Hubs
You can connect the DES-5024 to other switches and hubs on the network. The DES5024 is compatible with the DES-5016, DES-3216 and DES-3224. Port trunking can be
configured on the device if more than one port is connected between a DES-5024, DES5016, DES-3216 and DES-3224. Port trunking increases the efficiency of the DES-5024
by increasing the bandwidth. See the section on Port Trunking in Chapter 5 for
instructions on how to configure trunked ports.

Link
The Link LED indicates there is a link at the port. If a cable is plugged into the port and
the Link LED is off, check the cable and connection. The default value is that all ports
auto-negotiate the proper speed and duplex mode. If the port has been manually
configured for a particular speed and duplex mode, verify that the speed and duplex mode
of the port match the speed and duplex mode of the device you are connecting to.
The color of the Link LED indicates the port’s speed. Orange indicates the port is
operating at 10 Mbps. Green indicates the port is operating at 100 Mbps.
Duplex
The Duplex LED indicates the duplex mode the port is in. All 24 ports, and the expansion
modules, auto-negotiate the duplex mode by default. Each port can be manually set for a
particular speed and duplex mode. Off indicates the port is in half duplex mode. Green
indicates the port is in full duplex mode. Full duplex means the port is transmitting and
receiving data simultaneously. Half duplex means that data is only being transmitted or
received in one direction at a time.

Managing the DES-5024
This chapter shows the menus used to manage the DES-5024.
Three types of management are available on the DES-5024:
• Local Console Management (out-of-band)
• Telnet Management (in-band)
• D-View/ SNMP Management
The DES-5024 can be managed in-band or out-of-band. In-band management refers to
managing the DES-5024 through one of the MDI-X ports.
Out-of-band management means going through the RS-232 port.
The interface and options are the same with Local Console and Telnet Management. The
difference is the type of connection and the port that is used to manage the DES-5024.
D-View is a proprietary SNMP management program. D-View is provided with the DES-
5024. The DES-5024 supports other SNMP management applications and uses standard
MIB. Refer to appropriate documentation for installing and using other SNMP
application programs. The look and feel of D-View is different from other management
types. Refer to other documentation if you are using other vendors’ SNMP applications.
All instructions given in this chapter assume that you are logged into the DES-5024 and
are at the appropriate panel for carrying them out.
Managing the DES-5024

Fast Ethernet Switching System User’s Guide
Local Console Management
Local Console Management is always done through the RS-232 serial port and requires a
direct connection between the DES-5024 and a PC. This type of management is very
useful when the network is down and the DES-5024 cannot be reached by any other
means.
Use Local Console Management to log into the DES-5024 for the first time. You do not
need to know the IP address to log into the DES-5024 using Local Console Management.
You can change all the settings and configure the DES-5024, set the IP address and
perform other management functions. The management session will timeout after five
minutes if you have not taken any action. Press enter a few times to refresh the screen.
You will have to log in again after a timeout.
Follow these steps to begin a management session using Local Console Management:
1. Attach the male end of the RS-232 serial cable provided with the DES-5024 to the
RS-232 port located at the front of the DES-5024.
2. Attach the other end to the serial port of a PC or workstation.
3. Run a terminal emulation program using the following settings:
• Emulation: VT-100/ANSI compatible
• BPS: 19 200
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow Control: None
• Enable: Terminal keys
4. Press Enter to display the login panel.
5. Log in using the default User Name and Password. The User Name and Password are

System Rate Control
The System Rate Control panel, displayed in Figure 23, allows you to set the packet
forwarding rate on the DES-5024. There are two options: Store & Forward and CutThrough.
Figure 23: System Rate Control
The DES-5024 can be set for Store and Forward or Cut-Through. This is a global setting
that affects all the ports except the RS-232 port.
Store and Forward means that when the DES-5024 receives an incoming packet it
“stores” the packet until the entire data packet has been received before it “forwards” the
packet to a destination.
In Cut-Through mode the DES-5024 begins sending out the packet as soon as it receives
the first 128 bytes of data. The first 128 bytes contain the destination of the packet.
Advantages of Store and Forward
Store and Forward only sends out valid data packets. Bad packets created by collisions on
the network or damaged packets are filtered out.
Always use Store and Forward when some devices on the network run at 10 Mbps and
others run at 100 Mbps.
Disadvantages of Store and Forward
Store and Forward requires more time because it receives the whole packet before
sending it out. Every byte buffered is an additional eight microseconds of delay. For
Managing the DES-5024
44
Fast Ethernet Switching System User’s Guide
example, 1500 byte packets are delayed by 1200 microseconds in a Store and Forward
device versus 60 microseconds in a Cut-Through device.
Store and Forward requires more memory because the DES-5024 must store the packet
before sending it out.
Advantages of Cut-Through
Cut-Through is faster because the packet is sent as soon as the first 128 bytes are
received.
Cut-Through requires less memory since the DES-5024 only reads the address but does
not store the entire message.
Disadvantages of Cut-Through
Bad packets are perpetuated, taking up bandwidth.
The benefits diminish in high traffic networks.
Cut-Through can not be used on networks that use both Ethernet and Fast Ethernet. The
network must use one or the other.
Follow these steps to change the default setting from Store and Forward to Cut-Through:
1. Toggle the space bar to change the setting.
2. Select Save and press Enter.

The Switch Port Configuration menu, displayed in Figure 33, enables you to change the
configurations of individual ports.
Figure 33: Switch Port Configuration
State
All ports have two states: enabled or disabled. Enabled ports transmit and receive data
packets. Disabled ports can not transmit or receive packets. You can disable a port but
you will not be able to use a disabled port.
Physical
Refers to the physical state of the port. If you manually change the state of a port it will
remain in that state until you change it. It will not auto negotiate speed and duplex mode.
All TX ports can be in the following physical states:
• Auto
• 100Tx/Half
• 100Tx/Full
• 10Tx/Half
• 10Tx/Full
Ports in the Auto state automatically negotiate speed and duplex mode. This is the default
setting.
Ports set in the 100Tx/Half physical state are set to work at 100 Mbps half duplex.
Ports set in the 100Tx/Full state are set to work at 100 Mbps full duplex.
Managing the DES-5024
57
Fast Ethernet Switching System User’s Guide
Ports set in the 10Tx/Half state are set to work at 10 Mbps half duplex.
Ports set in the 10Tx/Full state are set to work at 10 Mbps full duplex.
The 100BASE-FX ports can only be in the 100/Fx Half or 100/Fx Full states. The
1000BASE-FX port can only be in 1000SX/Full. Half-duplex operation is not supported
in the Gigabit Module.
Port State
All ports have four states: blocking, listening, learning and forwarding. Blocking means
that nothing is coming through the port. If the Spanning Tree Algorithm detects a loop it
will change the state of the port where the loop is detected to the Blocking State. You can
disable the Spanning Tree Algorithm. Forwarding means the port is forwarding data
packets to their destination. Listening means that the port is listening for data packets.
Learning means the port is learning the MAC address for data packets. This setting
cannot be manually changed.
Priority
The port priority can be set from zero to 255. Zero is the highest port priority. The port
assigned a zero will be the root port. The default setting will work in most situations.
Flow Control
The 1000BASE-SX module allows you to enable or disable flow control. Flow control
allows the module to stop the flow of information from another device.

Spanning Tree Configuration
The Spanning Tree Configuration panel is used to configure the Spanning Tree
Algorithm. The Spanning Tree Algorithm (STA) in the DES-5024 allows you to create
alternative paths (using multiple switches or bridges) in your network. These backup
paths are idle until the DES-5024 determines that a problem has developed in the primary
path. If the primary path breaks down STA will activate the backup path. STA is very
complicated and you should understand it well before changing the default settings. See
Table 7: User Selective STA Parameters.
STA Operation Levels
STA operates on the bridge level and the port level. On the bridge level, STA calculates
the Bridge Identifier for each DES-5024, then sets the Root Bridge and the Designated
Bridges. On the port level, STA sets the Root Port and Designated Ports.
Spanning Tree Configuration Menu
The Spanning Tree Configuration menu, displayed in Figure 34, allows you to enable or
disable STA, set bridge priority and other configurations.
Figure 34: Spanning Tree Configuration
Managing the DES-5024
59
Fast Ethernet Switching System User’s Guide
Spanning Tree Algorithm
Spanning Tree Algorithm can be enabled or disabled. Use Spanning Tree to prevent
network loops.
Bridge Priority
The Bridge Priority can be from 0 to 65535. Zero is the highest Bridge Priority. The
higher the Bridge Priority the greater the chance that the DES-5024 will be selected as
the Root Bridge. The DES-5024 with the highest Bridge Priority is the Root Bridge.
Root Cost
The Root Cost is the number of times a packet is regenerated before reaching its
destination. A source sends a packet to the first device (switch or hub) on the network.
When the packet reaches the next hub or switch and is sent out again, the Path Cost
becomes two. Each switch and active hub regenerates the packet. To determine the Root
Path Cost, count the number of times the packet is regenerated.
The switch with the lowest Path Cost is the Root Bridge. Make the Root Bridge the best
switch on the network.
Hello Time
Is the interval between two transmissions of packets sent by the Root Bridge to tell all
other switches that it is the Root Bridge. The Hello Time can be set manually, with a
range in seconds from 1 to 10. If the Hello Time is set for the switch and the switch is not
the Root Bridge then the Hello Time will not take effect until the switch becomes the
Root Bridge.
Forward Delay Time
This is the time any port on the DES-5024 spends in the listening state while moving
from the listening state to the forwarding state. It can be set from 4 to 30 seconds.
Use the following formula when setting the Hello Time and the Forward Delay Time:
2 x (Forward Delay minus 1 second) > Max Age
2 x (Hello Time plus 1 second) < Max Age
Max Age Time
Is the time a non-root bridge waits for a packet to be sent. At the end of the Max Age, if a
packet has not been received from the Root Bridge, the DES-5024 will start sending its
own packets and request permission to become the Root Bridge. If it turns out that the
DES-5024 has the lowest Bridge Identifier it will become the Root Bridge.
Managing the DES-5024
60
Fast Ethernet Switching System User’s Guide
The switch with the lowest Bridge Identifier is the Root Bridge. It is best to make the
Root Bridge the best switch on the network to ensure the best network performance and
reliability.
Root Bridge
Specifies the MAC address of the Root Bridge. The DES-5024 may or may not be the
root bridge. The DES-5024 is the default root bridge.
Root Port
Specifies the preferred path to the Root Bridge. Only one path per bridge can exist. The
default setting is none.

SNMP Management Configuration
The SNMP Management Configuration panel is used to configure the DES-5024 for
SNMP management. Leave the default values in place if you are not managing your
network through SNMP.
The DES-5024 uses the standard MIB-II Management Information Base module. The
MIB values can be retrieved from any SNMP based network manager. The DES-5024
supports its own proprietary enterprise as an extended MIB. The MIB can be retrieved by
specifying their Object-Identity (OID). MIB values can be either read-only or read-write.
Read-only MIB variables can be constants that are programmed into the DES-5024 or
variables that change while the DES-5024 is running. For example, the number and type
of ports on the DES-5024 is a read-only constant. The number and type of ports is fixed.
Statistics, such as the number of errors that have occurred, are read-only variables.
Read-write MIBs are usually related to user customized configurations. Examples of
these are the DES-5024’s IP address, STA parameters and port status.
If you use third party vendors’ SNMP software to manage the DES-5024, a diskette
listing the DES-5024’s proprietary enterprise MIB can be obtained by request. If your
software provided functions to browse or modify MIB, you can get the MIB values and
change them (if the MIB’s attributes permit the write option). This process can be
difficult. You must know the MIB OIDs and retrieve them one by one.

You can name the SNMP communities anything you like. You can enter up to 32
characters in each of the four fields. You can create up to four SNMP Communities.
Access Right
Enables you to set the rights that members of the SNMP Communities have. Read Only
access rights mean that members of the community can view the information on the DES5024 but they can not make changes to the configurations. Read/ Write access rights
allow the members of the community to make any changes they desire.

Fast Ethernet Switching System User’s Guide
Status
Can be Valid or Invalid. Only communities with Valid status can access the DES-5024.
Communities with Invalid status cannot access the DES-5024.
SNMP Trap Manager Setting
Enables you to enter the IP addresses of Trap Managers. Traps are messages the DES5024 sends out to inform trap managers of events on the network. The DES-5024
generates traps and sends them to the network manager. Trap managers are special
network users who are given certain rights and access to oversee and maintain the
network. This feature is available only in D-View or by using other SNMP management
software.
You can specify which network managers may receive traps from the DES-5024 by
creating a list of IP Addresses of the authorized network managers.
Trap managers can receive the following trap types:
• Cold Start
• Authentication Failure
• Link Change Event
Cold Start
Signifies that the DES-5024 has been powered up. Software settings are reconfigured and
hardware systems are rebooted. A cold start is different from a factory reset.
Authentication Failure
Signifies that an addressee (or manager/ user) on the DES-5024 is not a valid user of the
DES-5024 and may have entered an incorrect community name.
Link Change Event
Signifies that the link of a port has changed from link up to link down or vice versa.
IP Address
This field is used to enter the IP Addresses of Trap Managers.
SNMP Community String

VLAN Port Management
A Virtual Local Area Network (VLAN) is a logical subgroup within a LAN that is
created with software rather than physical connections. The purpose of a VLAN is to
prevent broadcast storms and ease congestion on your network.
Each VLAN created is a broadcast domain. A broadcast is a packet that is sent to all
nodes on the network. A broadcast domain is a domain in which every node in the
domain receives the broadcast packet. The advantage of creating VLANs is that they
permit you to group LAN segments together in order to get the most out of your network.
VLANs become more important as the network grows and traffic increases. VLANs are
usually used on high traffic networks. You should consider a VLAN on a smaller
network if a department or workgroup routinely does tasks that take up a lot of bandwidth
and they are not already on their own LAN segment.
VLANs can be used to subdivide the network. The DES-5024 supports port based
VLAN. Port based VLAN means that the VLAN is grouped by port. If a VLAN is
created using three ports, then those ports become a separate broadcast domain.
By using VLANs, members of a particular department or workgroup can be partitioned
from the rest of the network. For example, the marketing department can be on one
VLAN and the accounting department can be on another. If a workstation in marketing
sends a broadcast packet to another workstation in marketing the packet will remain in
the marketing VLAN.

Troubleshooting
This troubleshooting section is intended to help you solve the most common problems on
the DES-5024.
The Diagnostic LED displays a code if there is a problem on the DES-5024. If an error
cannot be resolved by implementing the solutions in this section, contact D-Link
Technical Support.
All LEDs are explained in detail in Chapter 4, LEDs. If you are having a problem that is
not discussed here, contact technical support.
Problem Solution
POST Errors The DES-5024 performs a Power On Self Test (POST) every time
it is powered on. If you are connected to the DES-5024 through
Local Console Management during the POST you can see the
results displayed on your monitor. The login screen appears after
the DES-5024 has completed the POST.
The POST checks all of the hardware components on the DES-5024. See
Table 8: Diagnostic LED for proper actions.
Cables Faulty cable is the most common source of problems on Ethernet and Fast
Ethernet networks. Check the cable first if you are having any
problems connecting to a device.
Ethernet is more fault tolerant than Fast Ethernet. If you are moving from
Ethernet to Fast Ethernet, make sure the cables are pinned out
correctly. See Chapter 3, Connecting the DES-5024 to the
Network, Cable Specifications, for a diagram showing the proper
pin arrangement for Ethernet and Fast Ethernet.
Port StatesAll ports on the DES-5024 have two modes: auto negotiation mode and
forced mode. Ports in auto negotiation mode auto negotiate the
proper speed and duplex mode. Ports in forced mode have been
manually set to a particular speed and duplex mode. Check the
LEDs on the DES-5024 and on the link partner to verify settings.
See Chapter 4, LEDs, for an explanation of all LEDs.
The port settings on the DES-5024 and the port settings on the device you are
connecting to must be the same in order for them to communicate.
Check the speed and duplex setting on both the port and device
you are connecting to.
Power LED is Off Check the three pronged power plug and verify that you are getting
power from the wall socket. If the DES-5024 is on and the power
LED is not working properly return the DES-5024. If the DES-
