Note

This chapter describes how to make the initial connections to the switch and provides an overview of the web interface.

To enable remote management of the switch through a web browser, the switch must be connected to the network. The switch is preconfigured with an IP address for management purposes. After initial configuration, the switch can also be configured to acquire its address from a DHCP server on the network.

By default, the switch is assigned the following static IP information for access to the web interface:

■	IP address:	192.168.1.1
■	Network mask:	255.255.255.0

■Gateway: 0.0.0.0

1.Connect the switch to the management PC or to the network using any of the available network ports.

2.Power on the switch.

3.Set the IP address of the management PC’s network adaptor to be in the same subnet as the switch.

Example: Set it to IP address 192.168.1.2, mask 255.255.255.0.

4.Enter the IP address shown above in the web browser. See page 1-3 for web browser requirements.

Thereafter, use the web interface to configure a different IP address or configure the switch as a DHCP client so that it receives a dynamically assigned IP address from the network.

■If you enable DHCP for IP network configuration, the switch must be connected to the same network as the DHCP server. You will need to access your DHCP server to determine the IP address assigned to the switch.

■The switch supports LLDP (Link Layer Discovery Protocol), allowing discovery of its IP address from a connected device or management station.

■If DHCP is used for configuration and the switch fails to be configured, the IP address 192.168.1.1 is assigned to the switch interface.

After the switch is able to communicate on your network, enter its IP address into your web browser’s address field to access the switch management features.

•Blinking—The switch is receiving power through its Power Over Ethernet (PoE) port.

•Off—The switch is NOT receiving power.

■Fault/Locator (Orange)

•Blinking rapidly—A fault has occurred, other than during self-test.

•Blinking slowly—The locator function has been enabled to help physically locate the switch.

•On—If continuously on, no firmware was detected upon boot-up.

•Off—The locator function is disabled and the switch is operating properly.

Port LEDs

Each 10/100/1000 Mbps RJ45 port has two single-color LEDs that reflect the status of the actual LEDs on the switch. The upper LED indicates the link/activity status and the lower LED indicates the mode (speed).

The Link/Act LED status can be one of the following:

■On—A self-test is being performed on the port.

■Blinking—The port has network activity.

■Off—The port has no active network cable connected, is not receiving link signal, or is disabled. The function of the Mode LED changes depending on whether the switch supports Power-Over-Ethernet:

■When the switch supports PoE, the Mode LED indicates PoE status for port:

•On—PoE mode is enabled on the port.

•Blinking—The PoE port failed or is not currently providing power because it has temporarily exceeded its allocated power limit.

•Off—PoE mode is disabled on the port.

■When the switch does not support PoE, the Mode LED indicates port speed:

•On—The port is operating continuously at 1000 Mbps.

•Blinking—The port is operating at 100 Mbps.

•Off—The port is operating at 10 Mbps.

You can use the Setup Network pages to configure how a management computer connects to the switch and how the switch connects to a server to synchronize its time.

Use the Get Connected page to configure settings for the network interface. The network interface is defined by an IP address, subnet mask, and gateway. Any one of the switch's front-panel ports can be selected as the management port for the network interface. 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 forwarded except that, for the management port, the port VLAN ID (PVID) will be the management VLAN.

To display the Get Connected page, click Setup Network > Get Connected.

In the example configuration in Figure 3-1, the switch is configured to acquire its IP address through DHCP, which is the default setting. Access to the management software is restricted to members of VLAN 1.

Table 3-1. Get Connected Fields

Field	Description

Network Details

Protocol Type	Select the type of network connection:
	• Static—Select this option to enable the IP address, subnet mask, and gateway fields for
	data entry.
	• DHCP—Select this option to enable the switch to obtain IP information from a DHCP
	server on the network. If the DHCP server responds, then the assigned IP address is used.
	If DHCP is enabled but the DHCP server does not respond, the default static IP address
	192.168.1.1 is used. DHCP operation is enabled by default.
	When a server assigns an IP address to the switch, it specifies the time for which the
	assignment is valid. After the time expires, the server may reclaim the address for
	assignment to another device. When DHCP is enabled, you can click to send a request
	to the DHCP server to renew the lease.
	Only a user-configured, static IP address is saved to flash.
	CAUTION: Changing the protocol type or IP address discontinues the current connection;
	you can log on again using the new IP information.

IP Address	The IPv4 address to be used. The default IP address is 192.168.1.1.
	Note: A broadcast IP address cannot be entered in this field.

Subnet Mask	The IPv4 subnet address to be used. The default IP subnet address is 255.255.255.0.

Gateway Address	The IPv4 gateway address to be used. When in doubt, set this to be the same as the default
	gateway address used by your PC.

MAC Address	The burned-in universally administered MAC address of this switch.

Web Parameters

Session Timeout	Specify the amount of time in minutes that a connection to the web interface remains active,
	assuming no user activity. The range is 1 to 60 and the default is 5 minutes. To keep the
	connection active regardless of user activity, set this value to 0.
	CAUTION: When a session window is closed without logging out, the server connection
	remains open until the session times out. When the session timeout is set to 0, closing a
	session window without logging out keeps the session open at the server indefinitely. In such
	cases, you may fail to connect after the maximum sessions are left open indefinitely.

Management Access

Management VLAN	Access to the management software is controlled by the assignment of a management VLAN
ID	ID. Only ports that are members of the management VLAN allow access to the management
	software.
	By default, the management VLAN ID is 1. The allowed range is 1 to 4093. All ports are
	members of VLAN 1 by default; the administrator may want to create a different VLAN to
	assign as the management VLAN and associate it with a management port (see the next field).
	A VLAN that does not have any member ports (either tagged or untagged) cannot be
	configured as the management VLAN.
	When the network protocol is configured to be DHCP, any change in the configured
	management VLAN ID may cause disruption in connectivity because the switch acquires a
	new IP address when the management subnet is changed. To reconnect to the switch, the user
	must determine the new IP address by viewing the log on the DHCP server.

3-2

			Setup Network
			Get Connected

	Field	Description

	Management Port	Access to the management software can also be controlled by the selection of a management
		port. The selected management port is auto-configured to be an untagged member of the
		management VLAN and is excluded from any other untagged VLANs.
		When the switch boots with the default configuration, any port can be used as management
		port and this field is configured as 'None'.
		You can configure a management port to ensure that a port always remains an untagged
		member of the configured management VLAN; this helps to ensure management connectivity
		in case of an accidental change in VLAN membership.
		If no management port is specified, then all ports that are members of the management VLAN
		provide access to the switch management interface. If a management port is configured,
		access to the switch is restricted to that port. For example, if VLAN 1 is the management
		VLAN and port 10 is the management port, other ports that are members of VLAN 1 will
		not provide access to the switch management interface.

	SNMP

	SNMP	Enable or disable Simple Network Management Protocol (SNMP). If enabled, the
		administrator can view switch data using an SNMPv1/v2c manager. The switch supports
		read-only access to a limited set of MIBs. SNMP is enabled by default.

	Community Name	Specify a community name or use the default name, public.
		The switch supports the following MIBs:
		• BRIDGE-MIB (IEEE 802.1Q)
		• LLDP-MIB (IEEE 802.3AB)
		•	EtherLike-MIB
		•	IF-MIB
		•	RFC1213-MIB
		• RMON-MIB (RMON History as in v1)
		• Power Ethernet MIB (RFC3621), only on switches that support PoE+. (No SNMP
			information is available on configured PoE schedules.)

	Click Apply to save any changes for the current boot session. The changes take effect immediately.

Note	A power cycle does not reset the IP address to its factory-default value. If the configured IP address is unknown,
	you can perform a manual reset to factory defaults to regain access to the switch.
