IP Settings

The IP Setting screen contains fields for assigning IP addresses. IP addresses are either defined as static or are retrieved using the Dynamic Host Configuration Protocol

(DHCP). DHCP assigns dynamic IP addresses to devices on a network. DHCP ensures that network devices can have a different IP address every time the device connects to the network.

Note the following when configuring IP Addresses:

If the device fails to retrieve an IP address through DHCP, the default IP address is 192.168.0.239.

IPv4

Select whether to you wish to enable Static or DHCP for

Auto-Configuration. Next, enter the information for the IP address, gateway, and DNS servers.

To be managed over the network, the Switch needs an IP Address to be assigned. The IP Settings screen contains fields for assigning IP addresses. IP addresses are either defined as Static or are retrieved using the Dynamic Host Configuration Protocol (DHCP). DHCP assigns dynamic IP addresses to devices on a network. DHCP ensures that network devices have a different IP address every time the device connects to the network.

To access the page, click IP Settings under the System menu.

Important: If the device fails to retrieve an IP address through DHCP, the default IP address is: 192.168.0.239 and the factory default subnet mask is:

255.255.255.0.

To access the page, click IPv4 under IP Settings in the

System menu.

21

Dynamic IP Address (DHCP):	EnablestheIPaddresstobeconfigured
	automatically by the DHCP server.
	Select this option if you have a DHCP
	server that can assign the Switch an IP
	address, subnet mask, default gateway
	IP address, and a domain name server
	IP address automatically. Selecting this
	field disables the IP Address, Subnet
	mask,and Gatewayfields.
Static IP Address:	Allows the entry of an IP address,
	subnet mask, and a default gateway
	for the Switch. Select this option if
	you don’t have a DHCP server or if
	you wish to assign a static IP address
	to the Switch.
IP Address:	This field allows the entry of an
	IPv4 address to be assigned to this
	IP interface. Enter the IP address
	of your Switch in dotted decimal
	notation. The factory default value
	is: 192.168.0.239.
Subnet Mask:	A Bitmask that determines the
	extent of the subnet that the Switch
	is on. This should be labeled in the
	form: xxx.xxx.xxx.xxx, where each
	xxx is a number (represented in
	decimals) between 0 and 255. The
	value should be 255.0.0.0 for a Class
	A network, 255.255.0.0 for a Class
	B network, and 255.255.255.0 for a
	Class C network, but custom subnet
	masks are allowed. Enter the IP
	subnet mask of your Switch in dotted
	decimal notation. The factory default
	value is: 255.255.255.0.

Gateway:	Enter an IP address that determines
	where packets with a destination
	address outside the current subnet
	should be sent. This is usually the
	address of a router or a host acting
	as an IP gateway. If your network
	is not part of an Intranet, or you do
	not want the Switch to be accessible
	outside your local network, you can
	leave this field blank.
DNS Server (Domain Name	Used for mapping a domain name
System):	to its corresponding IP address and
	vice versa. Enter a DNS IP address
	in order to be able to use a domain
	name to access the Switch instead
	of using an IP address.

Apply: Click APPLY to update the the system settings.

22

IPv6

IPv6 is a an upgraded version to IPv4, providing more available IP addresses as well as other benefits. To access the switch over an IPv6 network you must first configure it with IPv6 information (IPv6 prefix, prefix length, and default gateway). To configure IPv6 for the Switch, select whether to you wish to enable Auto-Configura- tion, Static, or DHCP for the IPv6 State. Next, enter the information for the IP address, range, and gateway.

IPv6 State:	Select whether you wish to enable Auto
	Configuration, DHCPv6 Client, or Static for
	the IPv6 address.
Auto Configuration:	Use this option to set the IPv6 address for
	the IPv6 network interface in Auto Con-
	figuration. The Switch will automatically
	generate and use a globally-unique IPv6
	address based on the network prefix and
	its Ethernet MAC address.
DHCPv6 Client:	This enables the IP address to be config-
	ured automatically by the DHCP server.
	Select this option if you have an IPv6
	DHCP server that can assign the Switch
	an IPv6 address/Prefix and a default gate-
	way IP address.
Static:	Allows the entry of an IPv6 address/Pre-
	fix and a default gateway for the Switch.
	Select this option if you wish to assign
	static IPv6 address information to the
	Switch.
IPv6 Address:	This field allows the entry of an IPv6
	address/Prefix to be assigned to this IP
	interface.

Port: Displays the port number.

Link Status: Indicates whether the link is up or down.

Mode: Select the speed and the duplex mode of the Ethernet connection on this port.

Selecting Auto (Auto-Negotiation) allows one port to negotiate with a peer port automatically to obtain the connection speed and duplex mode that both ends support. When auto-negotiation is turned on, a port on the Switch negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer port does not support autoegotiation or turns off this feature, the Switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off, a port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer port are the same in order to connect.

Flow Control: A concentration of traffic on a port decreases port bandwidth and overflows buffer memory causing packet discards and frame losses. Flow Control is used to regulate transmission of signals to match the bandwidth of the receiving port. The Switch uses IEEE802.3x flow control in full duplex mode and backpressure flow control in half duplex mode.

IEEE802.3x flow control is used in full duplex mode to send a pause signal to the sending port, causing it to temporarily stop sending signals when the receiving port memory buffers fill.

Back Pressure flow control is typically used in half duplex mode to send a “collision” signal to the sending port (mimicking a state of packet collision) causing the sending port to temporarily stop sending signals and resend later.

PoE

Power Budget

The PoE Management screen contains system PoE information for monitoring the current power usage and assigns the total amount of power the Switch can provide to all of its PoE ports. Ports 1~8, 24, or 48 on the Switch are IEEE802.3at/af compliant ports. Each port is capable of delivering up to 30 Watts and a total PoE budget of either

130, 185, 370 or 740 Watts depending on your model for uninterrupted PoE use. To access the page, click PoE under the System menu.

PoE Port Settings

The EnGenius Layer 2 PoE+ Switches supports Power over Ethernet (PoE) as defined by the IEEE 802.3af and 802.3at. All ports can support PoE up to 30W. Ports 1-24 can supply about 48 VDC power to Powered Devices (PDs) over standard UTP Ethernet cables. The Switch follows the standard PSE (Power Sourcing Equipment) pinout, whereby power is sent out over pins 1, 2, 3 and 6.

EGS5212FP: Ports 1-8 supports both IEEE802.3 af and at. The maximum power budget is 130 Watts.

EGS7228P: Ports 1-24 supports both IEEE802.3 af and at. The maximum power budget is 185 Watts.

EGS7228FP: Ports 1-24 supports both IEEE802.3 af and at. The maximum power budget is 370 Watts and 720 Watts when you are using the EnGenius RPS370 external redundant power supply.

EGS7252FP: Ports 1-48 supports both IEEE802.3 af and at. The maximum power budget is 740 Watts.

Port:	Displays the specific port for which PoE parameters are defined.
	PoE parameters are assigned to the powered device that is
	connected to the selected port.
State:	• Enable – Enables the Device Discovery protocol and provides
	power to the device using the PoE module. The Device Discovery
	Protocol lets the device discover powered devices attached to
	device interfaces and learns their classification.
	• Disable – Disables the Device Discovery protocol and halts
	the power supply delivering power to the device using the PoE
	module.
Priority:	Select the port priority if the power supply is low. The field
	default is Low. For example, if the power supply is running
	at 99% usage, and port 1 is prioritized as high, but port 6 is
	prioritized as low, port 1 is prioritized to receive power and port
	6 may be denied power. The possible field values are: 4.
	• Low – Sets the PoE priority level as low.
	• Medium – Sets the PoE priority level as medium.
	• High – Sets the PoE priority level as high.
	• Critical – Sets the PoE priority level as critical.
