This chapter introduces the main features and applications of the switch. The switch comes in the following models:
MGS3600-24F 20-port GbE Fiber L2 Switch with Four GbE Combo Ports
XGS3600-26F 20-port GbE Fiber L2 Switch with Four GbE Combo Ports and Two 10G Fiber Ports
XGS3600-28F 20-port GbE Fiber L2 Switch with Four GbE Combo Ports and Four 10G Fiber Ports
The switch is a layer-2 standalone Ethernet switch with additional layer-2, layer-3, and layer-4 features suit able for Ethernet s. With it s built-in web
configurator, managing and configuring the switch is easy. In addition, the switch can also be managed via Telnet, any terminal emulator program
on the console port, or third-party SNMP management.
See “Firmware Specifications” on page 11-7 for a full list of software features available on the switch.
Use any of the following methods to manage the switch.
Web Configurator. This is recommended for everyday management of the switch using a (supported) web browser.
Command Line Interface. Line commands offer an alternative to the Web Configurator and may be necessary to configure advanced fea-
tures. See the CLI Reference Guide.
SNMP. The device can be monitored and/or managed by an SNMP manager. See “SNMP” on page 6-23.
Do the following things regularly to make the switch more secure and to manage the switch more effectively.
Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and let-
ters.
Write down the password and put it in a safe place.
Back up the configuration (and make sure you know how to restore it).
Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you
will have to reset the switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the switch. You could simply restore your last configuration.
For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the switch. This is especially important for enclosed rack installations.
This section lists the rack mounting requirements and precautions and describes the installation steps.
2.2.1 Rack-mounted Installation Requirements
Two mounting brackets.
Eight M3 flat head screws and a #2 Phillips screwdriver.
Four M5 flat head screws and a #2 Phillips screwdriver.
Failure to use the proper screws may damage the unit.
2.2.1.1 Precautions
Make sure the rack will safely support the combined weight of all the equipment it contains.
Make sure the position of the switch does not make the rack unstable or top heavy. Take all necessary precautions to anchor the rack
Connect these interfaces to local servers, routers or switches. Each interface
consists of a pair of ports — one SFP (100/1000 Mb) port and one RJ-45 (10/
100/1000Base-T) port. Only one port may be active at a time.

FRONT MATTER
Table 3-1: Front Panel Connections
CONNECTOR DESCRIPTION
5SFP+ Uplink Ports
(2 x 1/10 Gbps)
Connect these ports to the distribution layer of the network (XGS3600-28F
only).
6RS-232 Management PortConnect this port to an RS-232 interface to configure the switch using the
command line interface (CLI).
7RJ-45 Management Port
Connect this Ethernet port to the out-of-band remote management network.
There are four Dual Personality interfaces, comprising four 1000Base-T and four mini-GBIC combo ports. For each interface you can connect
either to the 1000Base-T port or the mini-GBIC port. The mini-GBIC ports have priority over the 1000Base-T ports. This means that if a mini-GBIC
port and the corresponding 1000Base-T port are connected at the same time, the 1000Base-T port will be disabled.
The switch has 24 (26 for the XGS3600-26F only) 1000Base-T mini-GBIC Ethernet ports. In 100/1000 Mbps Gigabit Ethernet, the speed can be
100 Mbps or 1000 Mbps. The duplex mode can be both half or full duplex at 100 Mbps and full duplex only at 1000 Mbps.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (100/1000 Mbps) and duplex mode (full duplex or half duplex) of the
connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight through or crossover Ethernet cable.
3.1.2.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the switch are:
These are 24 (26 for the XGS3600-26F only) slots for Small Form-Factor Pluggable (SFP) transceivers. A transceiver is a single unit that houses
a transmitter and a receiver. Use a transceiver to connect a fiber-optic cable to the switch. The switch does not come with transceivers. You must
use transceivers that comply with the Small Form-Factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s
INF-8074i specification Rev 1.0 for details.
You can change transceivers while the switch is operating. You can use different transceivers to connect to Ethernet switches with different types
of fiber-optic connectors.
Type: SFP connection interface
Connection speed: 1 Gigabit per second (Gbps) or 10 Gbps for the 2 uplink ports on the XGS3600-26F only
To avoid possible eye injury, do not look into an operating fiber optic module’s connectors.
Use the following procedures to connect the switch to a power source after you have installed it.
Make sure you are using the correct power source as shown on the panel and that no objects obstruct the airflow of the fans. Use only
power wires of the required diameter for connecting the switch to a power supply.
AC Power Connection
1. Connect the female end of the power cord to the power socket of your switch.
2. Connect the other end of the cord to a power outlet.
The switch uses a single ETB series terminal block plug with four pins which allows you to connect up to two separate power supplies. If one
power supply fails the system can operate on the remaining power supply. Use two wires to connect to a single terminal pair, one wire for the positive terminal and one wire for the negative terminal.
When installing the power wire, push it wire firmly into the terminal as deep as possible and make sure that no exposed (bare) wire can be
seen or touched.
Exposed power wire is dangerous. Use extreme care when connecting a DC power source to the device.
To connect a power supply:
1. Use a screwdriver to loosen the terminal block captive screws.
2. Connect one end of a power wire to the switch’s RTN (return) pin and tighten the captive screw.
3. Connect the other end of the power wire to the positive terminal on the power supply.
4. Connect one end of a power wire to the switch’s -48V (input) pin and tighten the captive screw.
5. Connect the other end of the power wire to the negative terminal on the power supply.
6. Insert the terminal block plug in the switch’s terminal block header.
For local management, you can use a computer with terminal emulation software configured to the following parameters:
VT100 terminal emulation
115200 bps
No parity, 8 data bits, 1 stop bit
No flow control
Connect the male 9-pin end of the RS-232 console cable to the console port of the switch. Connect the female end to a serial port (COM1, COM2
or other COM port) of your computer.

Clock SourceSelect Use Local Settings or Use NTP Server to set the time from the device's onboard
clock or from a remote NTP server.
Local TimeUse this field to set the device's onboard clock.
Time Zone OffsetUse this field to configure the time zone offset relative to UTC/GMT. This is also used
when NTP synchronizes time.
Daylight SavingsUse this check box to enable or disable daylight saving mode. In daylight saving mode,
the time will be offset by the Time Set Offset value between the From and To times.
Time Set OffsetUse this field to configure the daylight saving time offset. If this is non-zero, the From and
To fields must be configured to enable daylight saving mode.
Daylight Savings TypeSelect By dates or Recurring to configure how the From and To fields are used to define
daylight saving time. Select By dates to start and finish daylight saving on fixed dates.
Select Recurring to start and finish daylight saving on a day of the month.
FromUse this field to configure the start of daylight saving time. The top From field is active if
the By dates radio button is selected in Daylight Savings Type otherwise the bottom From
field is active.
ToUse this field to configure the end of daylight saving time. The top To field is active if the
By dates radio button is selected in Daylight Savings Type otherwise the bottom To field is
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong
to one group. A device can belong to more than one group. With VLANs, a device cannot directly talk to or hear from devices that are not in the
same group(s); the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLANs are vital in providing isolation and security among the subscribers. When properly configured,
VLANs prevent one subscriber from accessing the network resources of another on the same LAN, thus a user will not see the printers and hard
disks of another user in the same building.
VLANs also increase network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain. In traditional
switched environments, all broadcast packets go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast
domain.
VLANs are unidirectional; they only govern outgoing traffic.
Use the VLAN sub-menu to configure which ports can communicate with other ports. Use the VLAN Membership sub-menu to add, delete or
modify VLANs.
The following table describes the labels in this screen.
Table 5-3: Configuration > VLAN > VLAN membership
LABELDESCRIPTION
VLAN IDUse this field to configure the identity of this VLAN.
VLAN NameUse this field to configure the name of VLAN. The VLAN name can only contain alphabetic
or numeric characters and should contain at least one alphabetic character.
Port MembersUse these check boxes to configure membership for each VLAN ID. No ports are mem-
Use the IP Setup screen to configure the switch IP address, default gateway device, the default domain name server and the management VLAN
ID. The default gateway specifies the IP address of the default gateway (next hop) for outgoing traffic.
5.5.1 Management IP Addresses
The switch needs an IP address for it to be managed over the network. The factory default static IP address is 192.168.1.1. The subnet mask
specifies the network number portion of an IP address. The factory default subnet mask is 255.255.255.0. Inband configuration applies to nonmanagement ports and outband configuration applies only to the management port.
The switch gets its management IPv4 configuration via DHCP by default. If there is no DHCP server, the switch uses the static IP configuration.
To set the IPv4 configuration:
1. Click System > IP > IPv4.
2. Specify the IPv4 settings, and enable the DNS Proxy service if required.
The following table describes the labels in this screen.
Figure 5-5. System > IP > IPv4
Table 5-4: System > IP > IPv4
LABELDESCRIPTION
DHCP ClientUse this check box to enable or disable the DHCP client. If DHCP fails and the configured
IP address is zero, DHCP will retry. If DHCP fails and the configured IP address is nonzero, DHCP will stop and the static IP settings will be used. The DHCP client will
announce the configured System Name as host name to provide DNS lookup.
IP AddressUse this field to set the management IPv4 address of this switch.
IP MaskUse this field to set the IPv4 mask of this switch.
IP GatewayUse this field to set the IPv4 address of the default gateway.
VLAN IDUse this field to set the management VLAN ID. The allowed range is 1 to 4095.
DNS ServerUse this field to set the IPv4 address of the DNS Server.
DNS ProxyUse this check box to enable or disable the DNS Proxy. When DNS Proxy is enabled the
device appears as a DNS resolver to DNS clients connected to the device. Only valid
DNS requests are relayed to the DNS server on behalf of DNS clients connected to the
device. This helps to protect DNS clients against attack.
PortThis field shows the port number for this row.
LinkThis field shows the current link state. Green indicates the link is up and red that it is
down.
Current Link SpeedThis field shows the current link speed.
Configured Link SpeedUse this drop-down box to select a fixed link speed.
Flow ControlCheck the Configured column to use pause frames for flow control. The Current Rx col-
umn indicates whether pause frames on the port are obeyed, and the Current Tx column
indicates whether pause frames on the port are transmitted. If the configured link speed is
auto, the current Rx and Tx fields show the flow control capabilities of the link partner. If
the configured link speed is fixed, the current Rx and Tx fields reflect that setting. The cur-
rent Rx and Tx settings are determined by the result of the last Auto-Negotiation. Flow
control is not possible for half duplex (HDX) link speeds.
Maximum Frame SizeUse this field to configure the maximum frame size, including Frame Check Sequence
(FCS) allowed for the port.
Excessive Collision ModeUse this drop-down box to configure port transmit collision behavior. Possible collision
modes are:
Discard: Discard frame after 16 collisions (default).
Restart: Restart backoff algorithm after 16 collisions.
