Step 14.
Check the Status LEDs and confirm that all of the LEDs show status lights consistent
with normal operation.
Step 15.
You can start connecting all of the cables to the switch.
Grounding the Switch
You must install an external ground to all IT components. To this purpose there are two threaded screw
holes marked as grounds. Connect a ground wire to one of these grounds and connect the other end to a
valid ground. Do not rely on the power connection ground. If you choose to not use the ground screw,
make sure that there is a valid ground connection between the chassis of the switch and the grounded rack.
Test the ground using an Ohm meter.
Note: Grounding wires, screws, and connectors for the ground are not supplied by Mellanox.
Configuring the Switch for the First Time
Note: Unmanaged (Externally managed) switches, that is the IS5025 switches, do not get configured. On
unmanaged switches, the CONSOLE, Ethernet, and USB connectors are not found. Instead there is
an I2C connector.
Step 1.
Connect the host PC RS232 connector to the CONSOLE port of the switch using the supplied
cable
Note: No remote IP connection is available at this stage.
Step 2.
Configure a serial terminal program (for example, HyperTerminal, Minicom, or Tera
Term) on your host PC with the settings described in Table 3.
