The rear panel of this NexLog 840 shows the dual-redundant power supplies on
the left. On the right are two USB ports, two gigabit Ethernet ports, VGA output
(only available on blank front panel systems). Just to the left are audio in/out
(unused- use the front audio connectors instead), followed by two 9-pin RS-232
serial ports for ANI/ALI and SMDR integrations or for serial time
synchronization. To the left of those are ten telephony board slots. Slots 1 and 2
are shown filled. The board in Slot 1 holds the lowest-numbered channels. Note
that it is important when inserting additional boards into the system you must
fill in order from 1 to 10, and not skip slots.
2.2.5. NexLog 740 and NexLog 840 Blank Front Panel Units
The NexLog 740 and the NexLog 840 Blank Panel Unit require that a mouse,
monitor, and keyboard be plugged in for local configuration (setting of the IP
address). Note that once basic networking setup is completed, it is possible to
access all other configuration settings remotely via a web browser.
