Management Methods
The DES-5200 supports four management methods:
• Local Console Management
• Telnet Management
• Web Management
• D-View/ SNMP Management
Local Console Management
Local Console Management is done through the RS-232 Console port. Managing
the DES-5200 in this mode requires a direct connection between a PC and the
DES-5200.
Telnet Management
Telnet is done over the network. Once the DES-5200 is on the network, you can
use Telnet to log in and change the configuration.
D-View/ SNMP Management
The DES-5200 supports SNMP through D-View, D-Link’s proprietary SNMP
application and through other vendor’s SNMP applications. Please refer to the
appropriate documentation for instructions on installing and using D-View and
other SNMP applications.
Web Management
Web Management is done over the Internet. Once an Internet Protocol (IP)
address has been assigned to the DES-5200 it can be accessed over the web.
Software Update
Software can be updated quickly and easily. See the section Software Update
Menu, Chapter 5, for instructions on updating software.

Installing Optional Modules
The process for installing all modules is the same. You cannot change the position
of the CPU module. It must remain in the CPU slot. The DES-5200 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 procedure for installing all optional modules is the same for full size
and half size modules.
Follow these steps to install modules:
1. Power the DES-5200 off before installing or removing modules.
None of the modules are hot swappable. Removing or installing
modules while the DES-5200 is powered on can damage the DES5200 and the modules.
2. Grasp the thumbscrews on the side of the module or blank bracket
and turn counterclockwise to unscrew them. Remove the old
module or the blank bracket, as shown in Figure 9 and set aside.
Do not discard the module or blank bracket. Put the old module or
blank bracket back in if you remove the new module.
3. Install the new module by inserting it into the guides, see Figure
10, and sliding it in until it stops. Press in firmly until you feel the
module snap into place. The module should be level and flush with
the rest of the DES-5200 Never force, twist or bend the module.
The 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-5200 on after the new module is installed. The
DES-5200 will auto detect the module and it will appear on the
menu.
6. The 100BASE-FX and 1000-BASE-SX ports have dust covers
over the transceivers. Remove the dust covers before plugging in
the cable.
7. Check the LEDs to verify that there is a link at the port.
See the Troubleshooting section if the optional module is not working properly.

The power supply will adjust to the local power source automatically. The DES5200 may be plugged in without having any or with all LAN segment cables
connected.
The power plug is located at the rear of the DES-5200. Plug the cable into the
wall socket and plug the other end into the DES-5200. There is a power on/ off
switch located at the rear of the DES-5200. Move the switch to the on position to
power the DES-5200 on. The power LED will light and all ports will auto
negotiate the proper speed and duplex mode.
Reboot the DES-5200 if there is a problem. Contact D-Link Systems, Inc. for
technical support. Check the configuration of the DES-5200 after a power failure
but do not reset unless it is necessary.
The DES-5200 can be used with power sources in the range 100 to 240 VAC., 50
to 60 Hz.

Connecting the DES-5200 to the
This chapter covers the following:
• Cable Specifications
• Ports
• Connecting the DES-5200 to another DES-5200
• Connecting the DES-5200 to other switches and hubs
This section deals with making cables and connecting the DES-5200 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.

Network
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 most
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, and
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-5200 to work properly. See Figure 11, for an
example of straight through and crossover cable.
Connecting the DES-5200 to the Network
Fast Ethernet Switching System User’s Guide
21
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 4: Cable Specifications for Copper Connection, shows the cable
requirements for Ethernet and Fast Ethernet networks.
Table 4: Cable Specifications for Copper Connection
Ethernet Type Cable Requirements Maximum Length
10BASE-T Category 3, 4, and 5 UTP or STP 100 M (328 ft.)
100BASE-TX Category 3, 4, and 5 UTP or STP 100 M (328 ft.)

Fiber Optic Cable
Data can travel much farther over fiber optic cable than over Category 3, 4, or 5
cable. Cable length can be up to two kilometers (1.25 miles) in full duplex and
412 meters (1350 feet) in half duplex transmitting at 100 Mbps.
Fiber optic cables connected to the fiber expansion module for 100 Mbps must
meet the following specifications to carry 1300 nm wavelength for the specified
distance:
• Multi-mode cable ISO/IEC 793-2 type B1 and ITU-T G.652
standards
• Cable must have SC connectors
Fiber optic cables attached to the gigabit expansion module must meet the
following specifications to carry 850 nm wavelength for the specified distance:
• Multi-mode cable ISO/IEC 793-2 type B1 and ITU-T G.652
standards
• Cable must have SC connectors
Gigabit traffic can travel the following distances using the specified cable:
• 62.5 um cable 220 meters (720 feet)
• 50 um cables 500 meters (1639 feet)

Ports
MDI-X Ports
The ports in the 12-Port 10/100-TX module are MDI-X 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-5200 to 10 Mbps
devices or 100 Mbps devices are the same. All the ports will auto negotiate the
proper speed and duplex mode. There are two full sized TX modules and one half
sized TX module available for the DES-5200. The chassis supports a maximum of
28 10/100-TX ports.
Fiber Optic Ports
The DES-5200 supports 100BASE-FX and 1000BASE-SX. The chassis supports
a maximum of 20 100BASE-FX ports and a maximum of 2 1000BASE-SX ports.
There are two 100BASE-FX modules available: a full size 8-Port 100BASE-FX
module and a 2-Port 100BASE-FX half size module. The 100BASE-FX ports
support full and half duplex at 100 Mbps. The ports do not support 10 Mbps.
A half size 1-Port 1000BASE-SX module is available. The 1000BASE-SX
module only supports full duplex at 1000 Mbps.
Refer to Installing Optional Modules for installation instructions. Refer to Cable
Specifications for information on cable types and connectors.
Follow these steps to connect cables to the DES-5200:
1. Check for the appropriate cable configuration for each device.
2. Plug one end of the cable into any of the ports.
3. Plug the other end into the appropriate port on the other device.
4. Verify that the LED indicates connection at the proper speed and
duplex mode.
RS-232 Port
Follow these steps to connect the DES-5200 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.

DES-5200 to DES-5200 Connection
Two or more DES-5200s can be connected together through one or more media
ports. When connecting multiple ports to another DES-5200 use port trunking for
better performance. When bandwidth aggregation is desired, connect multiple
ports to another DES-5200. Refer to Chapter 5 for information about port
trunking.
Connecting the DES-5200 to other Switches
and Hubs
You can connect the DES-5200 to other switches and hubs on the network. The
DES-5200 is compatible with the DES-3216, DES-3224, DES-5016 and DES-
5024.

Console Based Management
This chapter covers three types of management:
• Console Management (out-of-band)
• Telnet Management (in-band)
• D-View/ SNMP Management
Web management is covered in Chapter 6.
The DES-5200 can be managed in-band or out-of-band. In-band management
refers to managing the DES-5200 through Telnet, using one of the ports.
Out-of-band management means going through the RS-232 port.
The interface and options are the same with Console and Telnet Management.
The difference is the type of connection and the port that is used to manage the
DES-5200. Telnet is In-Band Management.
5
D-View is a proprietary SNMP management program. D-View module is
provided with the DES-5200. The DES-5200 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 DView 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 DES5200 and are at the appropriate panel for carrying them out.
Managing the DES-5200
Fast Ethernet Switching System User’s Guide

Console Management
Console Management is always done through the RS-232 serial port and requires
a direct connection between the DES-5200 and a PC. This type of management is
very useful when the network is down and the DES-5200 cannot be reached by
any other means.
Use Console Management to log into the DES-5200 for the first time. You do not
need to know the IP address to log in using Console Management. You can
change all the settings and configure the DES-5200, 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 or Control + r to refresh
the screen. You will have to log in again after a timeout.
Follow these steps to begin a management session using Console Management:
1. Attach the male end of the RS-232 serial cable provided with the
DES-5200 to the RS-232 port located at the front of the DES-5200.
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
• Parity: None
• Stop bits: 1
• Flow Control: Xon/Xoff
• 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 case sensitive.
• User Name: D-Link
• Default Password: D-Link
6. Press Enter to reach the Main menu.

Telnet Management
You can manage the DES-5200 via Telnet session. However, first you must
assign a unique IP address to the DES-5200. Use Console Management to log into
the DES-5200 for the first time so that you can assign an IP address. Once you
have assigned an IP address to the DES-5200, you can use the management
method of your choice.
Telnet management can be done through any of the ports on the switch. You can
use any Telnet application that emulates a VT100 terminal. You must install
TCP/IP on the workstation before using Telnet. Only one Telnet session can be
active at a time.
Configuring Through the Ethernet Port
Follow these steps to manage the DES-5200 through a Telnet session:
1. Assign an IP address to the DES-5200.
2. Attach one end of an Ethernet cable to one of the Ethernet ports on
the DES-5200.
3. Attach the other end of the cable to a workstation.
4. Access the DES-5200 through Telnet.
5. Log into the DES-5200 using your user name and password.
The Telnet session will timeout after five minutes. Any changes that have not
been saved are lost. Press Enter to reconnect after a timeout.

System Rate Control
The System Rate Control panel, displayed in Figure 26, enables you to set the
packet forwarding rate on the DES-5200. There are two options: Store & Forward
and Cut-Through.
Figure 26: System Rate Control
The DES-5200 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-5200 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, packets are sent as soon as the first 128 bytes are received.
The first 128 bytes contain the destination address 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.
Managing the DES-5200
Fast Ethernet Switching System User’s Guide
50
For 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-5200 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-5200 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.

TFTP
TFTP is done using Telnet. It can be done from a remote location using a TFTP
server. The TFTP server and the DES-5200 must be on the same subnet. For
example, if the IP address of the DES-5200 is 100.100.100.001 then the TFTP
server must have an IP address beginning with 100.100.100. Only the last three
digits will be unique to the server and the DES-5200. Remember that two devices
cannot have the same IP address.
Follow these steps to update software using TFTP.

Switch Port Configuration Menu
The Switch Port Configuration menu, displayed in Figure 38, enables you to
change the configurations of individual ports.
Figure 38: 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. Disabled ports
cannot be used.
Physical
Refers to the physical state of the port. If the port state is manually changed it will
not change states. 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-5200
Fast Ethernet Switching System User’s Guide
66
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 Mpbs full duplex.
The 100BASE-FX ports can only be in the 100/ Half or 100/Full states. The
1000BASE-SX port can only be in 1000SX/Full. Half-duplex operation is not
supported.
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 changed manually.
Priority
The port priority can be set from zero to 255. Zero is the highest port priority. The
default setting will work in most situations.
Follow these steps to change the port state:
1. Select the State setting of the appropriate port.
2. Toggle the space bar to change the current setting.
3. Select Save and press Enter.

Spanning Tree Configuration
The Spanning Tree Configuration panel is used to configure the Spanning Tree
Algorithm. The Spanning Tree Algorithm (STA) in the DES-5200 enables you to
create alternative paths (using multiple switches or bridges) in your network.
These backup paths are idle until the DES-5200 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 12: 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-5200, 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 39, enables you to
enable or disable STA, set the bridge priority and other configurations.

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-5200 will be
selected as the Root Bridge. The DES-5200 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-5200 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-5200 will
start sending its own packets and request permission to become the Root Bridge.
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.

SNMP Management Configuration
The SNMP Management Configuration panel is used to configure the DES-5200
for SNMP management. Leave the default values in place if you are not managing
your network through SNMP.
The DES-5200 uses the standard MIB-II Management Information Base module.
The MIB values can be retrieved from any SNMP based network manager. The
DES-5200 supports its own proprietary enterprise as an extended MIB. The MIB
can be retrieved by specifying their Object-Identity (OID). MIB values can be
read-only or read-write.
Read-only MIB variables can be constants that are programmed into the DES5200 or variables that change while the DES-5200 is running. For example, the
number and type of ports on the DES-5200 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-5200’s IP address, STA parameters and port status.
If you use third party vendors’ SNMP software to manage the DES-5200, a
diskette listing the DES-5200’s proprietary enterprise MIB can be obtained by
request. If your software provides 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 OID’s and retrieve
them individually.

configurations. Read/ Write access rights enable the members of the community
to make any changes they desire.
Status
Can be Valid or Invalid. Only communities with Valid status can access the DES-
5200. Communities with Invalid status cannot access the DES-5200.
SNMP Trap Manager Setting
Enables you to enter the IP address of Trap Managers. Traps are messages the
DES-5200 sends out to inform trap managers of events on the network. The DES5200 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-5200
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-5200 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-5200 is not a valid user
of the DES-5200 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.

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 the 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-5200 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 on the marketing VLAN.

The DES-5200 can be managed through an Internet connection. This type of
connection is called Web Management. The panels look different but they have
the same information and function as Console Based Management.
Using Web Management
You can use your web browser to configure and manage the DES-5200. The
DES-5200 must have an IP address in order to be managed over the web. Log in
through Local Console Management the first time and assign an IP address to the
DES-5200. All subsequent management sessions can be done over the web.
Follow these steps to configure the DES-5200 for web based management:
1. Enter the IP address of the DES-5200 in the address field of your
Web browser and press Enter.
