2-2 LED Indicators
There are diagnostic LEDs located on the front panel of HUG-800GSN & HUG-800GSEN. They provide
primary information on switch status as described in the table below.
LED Name LED Color Status Definition
ON
Power is connected and active at the PWR1/PWR2 input terminal
connection.
PWR1
PWR2
Green
OFF PWR1/PWR2 is not connected.
On
One of the power inputs has fault condition (Alarm DIP switch must
be enabled).
Fault
Amber
Off
Normal operation without power faults or Alarm DIP switch is
disabled..
On The connected LAN speed is 1000M.
Blinking Blinking when there is Ethernet traffic.
1000 Yellow
Off There is no Ethernet connection
On The connected LAN speed is 10M or 100M
Blinking Blinking when there is Ethernet traffic.
100 Green
Off There is no Ethernet connection
2-3 DIP Switch
There is DIP switch located on the top panel of HUG-800GSN & HUG-800GSEN. It provides setup options
on power alarm, EEE (Green Ethernet) and broadcast storm protection (BSP), and these functions as
described in the table below.
DIP Function Status Description
Alarm Enable*
Provide alarm relay and fault LED indication if there is a power failure in
one supply.
1
Alarm Disable
Disable alarm relay and fault LED indication if there is a power failure in
one supply. Connecting to a single power source, place this switch to
Disable position to turn off this function.
Broadcast Enable*
Enable broadcast storm protection. When BSP is enabled the switch will
detect the broadcast packet per 10ms, and it only accepts 2 packets per
10ms, if broadcast packet has exceeded 2 packets, and the 3rd packet
will be drop in order to protect the switch from possible broadcast storm.
2
Broadcast Disable
Disable the broadcast storm protection. When disabled, packets will not
be dropped. However, the network performance may be affected or in the
worst situation the network may be melted down due to excessive
network traffic.
Enable
Enable IEEE802.3az Green Power function. Power usage will be reduced
when there is low or no traffic utilization.
3
Green
Power
Disable*
Disable IEEE802.3az Green Power function. No power saving plan will be
carried out when there is low or no traffic utilization.
*Switch’s default setting
* After changing the DIP switch setting, you must restart the device (Power ON/OFF again) to activate the setting.
2-4 RJ-45 Ports
HUG-800GSN & HUG-800GSEN has 8 10/100/1000Mbps auto-sensing ports for 10Base-T, 100Base-TX
and 1000Base-T devices connection. Auto MDI/MDIX function allows HUG-800GSN & HUG-800GSEN to
connect to another switch or workstation without changing straight through or crossover cabling. See RJ-45
Pin Assignment section for straight through and crossover cable schematic.
