Verifying
Connectivity
After all Ethernet and/or fiber connections are made, check the LED’s corresponding to the
ports that each of the devices are connected to. Ensure that for each port that is in use, the
LED is on or blinking. If a port LED is off, go back and check for connectivity problems
between that port and the network device connected to that particular port.
Console Port
Management
The switch can be software configured via an RJ45 RS232 console port. See the images
below. This manual only details on how to connect to this port. Refer to the software manual
for details on how to configure the switch via this port.
RS232 RJ45 Port
The RJ-
45 serial port on the switch’s front panel is used to connect to the switch for out-of-
band console configuration. The on-board configuration program can be accessed from a
terminal or a PC running a terminal emulation program. The console cable is an RJ45 to DB9
adapter included with the unit, part number EL326CNSCBL. The pin assignments used to
connect to the serial port are provided in the following table:
Switch Console Port PC RS232 Port
6 RXD (receive data) 3 TXD (transmit data)
3 TXD (transmit data) 2 RXD (receive data)
5 SGND (signal ground) 5 SGND (signal ground)
No other pins are used. PC should be configured for a
baud rate of 115,200, 8-N-1, 8 data bits and no flow
control.
Connecting
Switches in a
Stack
In line-topology stacking there is a single stack cable connection between each switch that
carries two-way communications across the stack. In ring-topology stacking, an extra cable is
connected between the top and bottom switches forming a “ring” or “closed-loop.” The closed-
loop cable provides a redundant path for the stack link, so if one link fails, stack
communications can still be maintained.
