Switch Installation
Desktop Hardware Installation
The site where you install the hub stack may greatly affect its performance. When
installing, consider the following pointers:
Note: The switch model may be different than the one shown in the example
illustrations.
•Install the Switch in a fairly cool and dry place.
•Install the Switch in a site free from strong electromagnetic field generators (such
as motors), vibration, dust, and direct exposure to sunlight.
•Leave at least 10cm of space at the front and rear of the hub for ventilation.
•Install the Switch on a sturdy, level surface that can support its weight, or in an
EIA standard-size equipment rack. For information on rack installation, see the
next section, Rack Mounting.
•When installing the Switch on a level surface, attach the rubber feet to the
bottom of each device. The rubber feet cushion the hub and protect the hub
case from scratching.
Rack Mount Hardware Installation
The switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in
a wiring closet with other equipment. Attach the mounting brackets at the switch’s
front panel (one on each side), and secure them with the provided screws.
Note: The switch model may be different than the one shown in the example
illustrations.
Then, use screws provided with the equipment rack to mount each switch in the rack.

Connect additional devices to your switch
You can connect additional computers or other network devices to your switch using Ethernet cables to connect them to one of the available Gigabit Ethernet Ports (1-48). Check the
status of the LED indicators on the front panel of your switch to ensure the physical cable connection from your computer or device.
Note: If you encounter issues connecting to your network, there may be a problem with your computer or device network settings. Please ensure that your computer or device network
settings (also called TCP/IP settings) are configured properly within the network subnet your switch is connected.

Set your IPv6 settings
System > IPv6 System Settings
Internet Protocol version 6 (IPv6) is a new IP protocol designed to replace IP version 4
(IPv4). The IPv6 address protocol meets the current requirements of new applications
and the never ending growth of the Internet. The IPv6 address space makes more
addresses available but it must be approached with careful planning. Successful
deployment of IPv6 can be achieved with existing IPv4 infrastructures. With proper
planning and design, the transition between IP version 4 and 6 is possible today as well.
Use the IPv6 System Settings page to configure the IPv6 network interface, which is the
logical interface used for in-band connectivity with the switch via all of the switch's
front-panel ports. The configuration parameters associated with the switch's network
interface do not affect the configuration of the front-panel ports through which traffic is
switched or routed.
1. Log into your switch management page (see “Access your switch management page”
on page 7).
2. Click on System, and click on IPv6 System Settings.
3. Review the settings. When you have completed making changes, click Apply to save
the settings.
•IPv6 State: The IPv6 address for the IPv6 network interface is set in auto
configuration mode if this option is enabled. The default value is Disable. Auto
configuration can be enabled only when DHCPv6 is not enabled on any of the
management interfaces. DHCPv6 Client: This option only displays when
DHCPv6 is enabled.
•IPv6 Unicast Address / Prefix Length: The IPv6 Unicast Address is an identifier
for a single interface, on a single node. A packet that is sent to a unicast
address is delivered to the interface identified by that address. Add the IPv6
prefix and prefix length to the IPv6 System Settings interface.
•IPv6 Static Gateway: Specifies the corresponding Gateway of the IP address
entered into the field.
•IPv6 Dynamic Gateway: To configure the switch to automatically obtain its IP
configuration from a DHCP server on your network.
•NS Retransmit Time Settings: A constant that defines a nonzero number of
seconds between periodic reauthentication of the client. The field is 1~3600
seconds. The default setting is 1 second.
•Link Local Address Settings: A link-local address is an IPv6 unicast address that
can be automatically configured on any interface using the link-local prefix
FE80::/10 (1111 1110 10) and the interface identifier in the modified EUI-64
format. Link-local addresses are used in the neighbor discovery protocol and
the stateless autoconfiguration process. Nodes on a local link can use link-local
addresses to communicate; the nodes do not need globally unique addresses
to communicate. IPv6 devices must not forward packets that have link-local
source or destination addresses to other links.
•Automatic Link Local Address: A link local address has a prefix of FE80, is not
routable, and can be used for communication only on the local network. Only
one link local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
•Link Local Address/Prefix length: Enter the Link Local Address/Prefix Length.
