other descriptions. The allowed string length is 0~255 and the allowed content is the ASCII characters from
32~126.
System Name: Indicate the hostname for this device. Alphabets (A-Z; a-z), digits (0-9) and minus sign (-) can be
used. However, space characters are not allowed. The first character must be an alphabet character. The first and
last character must not be a minus sign. The allowed string length is 0~255.
System Location: Indicate the location of this device. The allowed string length is 0~255.
2-2 System Information
The system information screen will display the configuration information of the system, in System section shows
“Contact”, “Name” and “Location”, the Hardware section shows “MAC Address” and “Hardware Version”, the Time
section shows “System Date” and “System Uptime" and the Software section shows the “Software Version” and
“Software Date”.
HMG-838PT & HMG-838EPT Web Configuration 2-1
2-3 System IP
The section allows you to setup the switch’s IP configuration, interface and routes.
System
IP Configuration:
Mode: The pull-down configures whether the IP stack should act as a Host or a Router.
Host: IP traffic between interfaces will not be routed.
Router: Traffic is routed between all interfaces. When configuring this device for multiple VLANs, the Router
mode should be chosen.
DNS Server: This setting controls the DNS name resolution done by the switch. The following modes are
supported:
From any DHCP interfaces: The first DNS server offered from a DHCP lease to a DHCP-enabled interface
will be used.
No DNS server: No DNS server will be used.
Configured: Explicitly provide the IP address of the DNS Server in dotted decimal notation.
From this DHCP interface: Specify from which DHCP-enabled interface a provided DNS server should be
preferred.
DNS Proxy: When DNS proxy is enabled, the system will relay DNS requests to the currently configured DNS
server, and reply as a DNS resolver to the client devices on the network.
HMG-838PT & HMG-838EPT Web Configuration 2-2
System
IP Interface:
Click "Add Interface" to add a new IP interface. A maximum of 8 interfaces is supported.
VLAN: This is the VLAN associated with the IP interface. Only ports in this VLAN will be able to access the IP
interface. This field is only available for input when creating a new interface.
DHCP: When this checkbox is enabled, the system will configure the IPv4 address and mask of the interface
using the DHCP protocol. The DHCP client will announce the configured System Name as hostname to provide
DNS lookup.
IPv4 Address: The IPv4 address of the interface is entered in dotted decimal notation. If DHCP is enabled, this
field is not used. The field may also be left blank if IPv4 operation on the interface is not desired.
IPv4 Mask: The IPv4 network mask is entered by a number of bits (prefix length). Valid values are between 0 and
30 bits for a IPv4 address. If DHCP is enabled, this field is not used. The field may also be left blank if IPv4
operation on the interface is not desired.
IPv4 Current Lease: For DHCP interfaces with an active lease, this column shows the current interface address,
as provided by the DHCP server.
IPv6 Address: An IPv6 address is a 128-bit record represented as eight fields of up to four hexadecimal digits
with a colon separating each field (:). For example, fe80::215:c5ff:fe03:4dc7. The symbol :: is a special syntax that
can be used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it can appear only
once. It can also represent a legally valid IPv4 address. For example, ::192.1.2.34. The field may be left blank if
IPv6 operation on the interface is not desired.
IPv6 Mask: The IPv6 network mask is entered by a number of bits (prefix length). Valid values are between 1 and
128 bits for an IPv6 address. The field may be left blank if IPv6 operation on the interface is not desired.
IP Routes:
Route Network: The IP route is the destination IP network or host address of this route. Valid format is dotted
decimal notation or a valid IPv6 notation. A default route can use the value 0.0.0.0 or for IPv6 use the :: notation.
Route Mask: The route mask is a destination IP network or host mask, in number of bits (prefix length). It defines
how much of a network address that must match, in order to qualify for this route. Valid values are between 0 and
32 bits respectively 128 for IPv6 routes. Only a default route will have a mask length of 0 (as it will match
anything).
Gateway: This is the IP address of the gateway. Valid format is dotted decimal notation or a valid IPv6 notation.
Gateway and Network must be of the same type.
2-4 System IP Status
Display the status of IP interfaces and routes.
HMG-838PT & HMG-838EPT Web Configuration 2-3
System
Please refer to “System IP” for the configuration of the interfaces and routes. This page is informational only.
2-5 System NTP
Display the status of IP interfaces and routes.
NTP Configuration:
Mode: Configure the NTP mode operation. Possible modes are:
Enabled: Enable NTP client mode operation.
Disabled: Disable NTP client mode operation.
Server #: Enter the IPv4 or IPv6 address of an NTP server. IPv6 address is in 128-bit records represented as
eight fields of up to four hexadecimal digits with a colon separating each field (:). For example,
'fe80::218:a9ff:fe00:4ec0'. The symbol '::' is a special syntax that can be used as a shorthand way of representing
multiple 16-bit groups of contiguous zeros; but it can appear only once. NTP servers can also be represented by a
legally valid IPv4 address. For example, '::192.1.2.34'. The NTP servers are tried in numeric order. If 'Server 1' is
unavailable, the NTP client will try to contact 'Server 2'.
Note: The NTP Server support is only support NTPv4 Protocol.
HMG-838PT & HMG-838EPT Web Configuration 2-4
2-6 System Time

3-2 Green Ethernet Configuration
Configure EEE (Energy-Efficient Ethernet) as well as Ethernet power savings.
HMG-838PT & HMG-838EPT Web Configuration 3-1
Green Ethernet
Port Power Savings Configuration:
Optimize EEE for: Enables/disables the EEE function for this switch. The two options are:
Power: The EEE function is enabled. This is the default setting.
Legacy: EEE is not enabled.
Port Configuration:
ActiPHY™: ActiPHY™ works by lowering the power for a port when there is no link. The port is power up for short
moment in order to determine if an Ethernet cable is inserted. For ports with no cable connection, the PHY
remains powered down to save energy.
PerfectReach™: PerfectReach™ is another power saving mechanism. PerfectReach™ works by determining the
cable length and lowering the Ethernet transmit power for ports with short cables.
EEE (Energy-Efficient Ethernet): EEE is a power saving option that reduces the power usage when there is low
or no traffic utilization. EEE was developed through the IEEE802.3az task force of the Institute of Electrical and
Electronic Engineers (IEEE). EEE works by powering down circuits when there is no traffic. When a port gets data
to be transmitted all circuits are powered up. The time it takes to power up the circuits is called wakeup time. The
default wakeup time is 30 us for 100Mbit links. EEE devices must agree upon the value of the wakeup time in
order to make sure that both the receiving and transmitting device has all circuits powered up when traffic is
transmitted. The devices can exchange wakeup time information using the LLDP (Link Layer Discovery Protocol)
protocol. EEE works for ports in auto-negotiation mode, where the port is negotiated to either 10 or 100 Mbit full
duplex modes. For ports that are not EEE-capable the corresponding EEE checkboxes are grayed out and thus
impossible to enable EEE for.
When a port is powered down for saving power, outgoing traffic is stored in a buffer until the port is powered up
again. Because there are some overhead in turning the port down and up, more power can be saved if the traffic
can be buffered up until a large burst of traffic can be transmitted. Buffering traffic will give some latency in the
traffic. For traffic that should not be held back, urgent queues may be assigned to reduce latency yet still result in
overall power saving.
EEE Urgent Queues: It is possible to minimize the latency for specific frames, by mapping the frames to a
specific queue (done with QOS), and then mark the queue as an urgent queue. When an urgent queue gets data
to be transmitted, the circuits will be powered up at once and the latency will be reduced to the wakeup time.
Queues set will activate transmission of frames as soon as data is available. Otherwise the queue will postpone
HMG-838PT & HMG-838EPT Web Configuration 3-2
transmission until a burst of frames can be transmitted.

Green Ethernet
Port Power Savings Status:
In the above we can see that port 8 is saving power through PerfectReach™ as the Ethernet cable is short. Our port 6 is
connected to an EEE compliant device but with short cable, so we have savings both by EEE and PerfectReach™. As
for rest other ports do not linked to any devices, so they are saving power via ActiPHY™. It should be noted that
Ethernet power savings do not apply to the optical fiber ports, only to the electrical LAN ports.

supported by the specific port are shown.
Copper Ports
Fiber Ports
HMG-838PT & HMG-838EPT Web Configuration 4-1
Possible copper port settings are:
Disabled: Disables the switch port operation.
Auto: Port auto negotiating speed with the link partner, selecting the highest speed that is compatible with
the link partner and negotiating the duplex mode.
10Mbps HDX: Forces the port to 10Mbps half duplex mode.
10Mbps FDX: Forces the port to 10Mbps full duplex mode.
100Mbps HDX: Forces the port to 100Mbps half duplex mode.
100Mbps FDX: Forces the port to 100Mbps full duplex mode.
Possible fiber port settings are:
Disabled: Disables the switch port operation.
Auto: The auto-negotiation function in fiber optic network is to negotiate on the duplex mode only, not the
speed of the SFP.
100Mbps FDX: Forces the fiber port to 100Mbps full duplex mode.
1Gbps FDX: Forces the fiber port to 1Gbps full duplex mode. (System Default)
Flow Control: The Current Rx column indicates whether pause frames on the port are obeyed, and the Current
Tx column indicates whether pause frames on the port are transmitted. The Rx and Tx settings are determined by
the result of the last Auto-Negotiation. Check the configured column to use flow control. This setting is also related
to the setting for Configured Link Speed.
Ports
Maximum Frame Size: Enter the maximum frame size allowed for the switch port, including FCS. This switch
supports up to 9600 byte packets.
Excessive Collision Mode: This setting configures the port transmit collision behavior to either "Discard"
(Discard frame after 16 collisions - default) or to "Restart" (Restart back off algorithm after 16 collisions).
Note: The Auto-Negotiation function that supported by SFP port, is to negotiate on the duplex mode only, not the speed of the SFP,
our system’s default speed for SFP port is 1Gbps, if you wish to use 100Mbps SFP module please manually setup the port speed
to “100Mbps FDX”.
