Chapter 3 Description of the equipment

The outward appearance of the equipment can be seen in the following figure. Here you can see both the
front panel and the various rear panels depending on the version.
On the front panel, you can see the LEDs which display the status of the various interfaces and devices that
the Atlas 250 router has.
Located on the rear panel is the power point, the AUX console connection (in DB-9 format) for local configur-
ation and monitoring and the micro-switches. From the communications point of view, you will find the con-
nection to the LAN (in RJ45 format) with the link LED (in yellow), the ISDN connection (in RJ24 format) with
the TERM pushbutton controlling the ISDN bus terminal resistance and the WAN connectors (in DB-25
format). Finally, depending on the version, you will find diverse types of slots which permit access to the
various expansion cards that can be situated in the interior of the device. By default, these slots are protec-
ted by blind covers and once removed allow you to access the distinct connectors supporting the expansion
cards.
