BIG 101x
Version: 2010/12/01 35
The front view on the left shows the Ethernet ports (LAN1 for LCT and LAN2 – LAN4 for
the LAN-connection). In addition to that, the front panel provides a socket for the 12 V power
supply and the WAN-connection (4 × SHDSL).
On the side of the BIG 101x there is the Reset button (behind the right-side service opening,
as shown in figure 4), which can be operated by means of a pin / a paperclip. If this button is
pressed for a few seconds (< 4 s), the BIG 101x will perform a reset (rebooting). By keeping
the button pressed for more than 4 seconds, all user data will be reset (low-level access).
While the button is pressed, the LED for LINK and LAN (including all status LEDs) are
flashing up subsequently.
The data reset from the high-level access is realized through a special procedure (see subsec-
tion 3.3).
Figure 4: Side view
The LED display section is on the right upper part of the BIG 101x housing. The LEDs pro-
vide the following information (For details see subsection 2.9):
LED PWR (yellow): Internal power supply status information
LED ALARM (red): Signalling of alarm conditions
LED LINK (green / yellow): Status display of the WAN-interface (SHDSL)
LED LAN (green / yellow): Status display of the LAN-interface (LAN1 ... LAN4)
2.5 Power supply
Power supply of the device is effected through an external wall power supply 12 V / 1.2 A,
which is equipped with a two-pin Europlug and included in delivery.
The input voltage of the mains unit ranges between 100 V … 240 V (50 Hz … 60 Hz), the
output voltage of the BIG 101x is 12 V DC.
2.6 LCT-port and integrated Web-Server (LAN1)
The LAN1-interface has been configured as LCT-port (Local Craft Terminal). The LCT-port
provides direct access to the integrated Web-Server (Web-GUI). To protect the settings and
configurations, which can be realized via the Web-Server, against unauthorized access, the
BIG 101x has a dual access protection:
Low-level access mainly enables access to statistical information.
High-level access makes all read/write rights available to the user. The user may carry out
configurations at the WAN- and LAN-port, and he/she can change the switch settings. It is
also possible to perform a software update of the BIG 101x and a reset to its default settings.
Local access to the Web server can be influenced via SNMP-Remote access.
