PWR Illuminates GREEN to indicate power applied.
LK/ ACT Steady ON for LINK w/no traffic, blinking for activity per port. LINK will turn off in the event connectivity
is lost between the ends of the twisted pair segment or a loss of power occurs in the unit or remote device.
The Link ports are also represented by LA1, LA2, LA3...LA6. (Steady On or steady Off indicates no Receive
Activity).
10/100 Steady ON for 100Mb speed, OFF for 10Mb speed per port (copper ports)
F/H (FH1, FH2) Steady ON for Full duplex (F/D) mode, OFF for Half duplex (H/D) mode per port (fiber port only)
NOTE: The port #1 and 2 is being assigned for copper or fiber port for different models.
4.4 Hardware operated Alarm Contact for monitoring
internal power supply
The two screws Alarm Contacts feature, standard on
DFG48044X, provides Normally Closed (NC) contacts to which
the user can attach one sets of status monitoring wires at the
green terminal block. When this option is present, the
terminal block for Alarm Contacts is part of the Power Input
panel in the DFG48044X case. The DC power input connection
is in the same panel.
The NC Alarm Contact is held close when there is power on the main board inside of the DFG48044. This
provides a "Hardware operated Alarm" because the NC contacts will open when internal power is lost, either from
an external power down condition or by the failure of the power supply inside of the DFG48044X Switch. Useful
info about Alarm Contacts in DFG48044X:
1. Two-position terminal block (1, 2) provided next to the DC power input, as shown above.
2. The Alarm Relay contact connected to the two terminals (1, 2) is hardware operated.
3. By default it is NC (normally closed). It will open if there is any loss of power to the electronics inside of the
unit.
5.0 TROUBLESHOOTING
All Ethernet products are designed to provide reliability and consistently high performance in all network
environments. The installation of DFG48044X Series 10/100 Mb/s Switches is a straightforward procedure (see
INSTALLATION, Section 3.0); the operation is also straightforward and is discussed in Section 4.
Should problems develop during installation or operation, this section is intended to help locate, identify and
correct these types of problems. Please follow the suggestions listed below prior to contacting your supplier.
However, if you are unsure of the procedures described in this section or if the DFG48044X Series 10/100 Mb/s
Switch is not performing as expected, do not attempt to repair the unit; instead contact your supplier for
assistance or contact company.
