Grounding The Switch; Cable Installation - Mellanox Technologies InfiniScale MIS5022Q-1BRR User Manual

InfiniScale® IV 8-Port QSFP 40 Gb/s InfiniBand Switch User Manual
Caution: When turning off the switch, make sure ALL Connector LEDS are off to
ensure a powered down status.

5.2.5 Grounding the Switch

Check to determine if your local or national electrical codes require an external ground to all IT
components. If so, connect a ground wire to one of the casing screws and connect the other end to
a valid ground. If you choose to not use the ground screw, make sure that the rack is properly
grounded and that there is a valid ground connection between the chassis of the switch and the
rack. Test the ground using an Ohm meter.
Some national and/or local codes may require IT components to be bonded and exter-
nally grounded (not including the power cord ground). You must follow all national
and local codes when installing this equipment.

5.2.6 Cable Installation

All cables can be inserted or removed with the unit powered on. To insert a cable, press the con-
nector into the port receptacle until the connector is firmly seated. The orange LED indicator cor-
responding to each port will light when the physical connection is established (that is, when the
unit is powered on and a cable is plugged into the port with the other end of the connector plugged
into a functioning port). After plugging in a cable, lock the connector using the latching mecha-
nism particular to the cable vendor. When a logical connection is made the green light will come
on. When data is being transferred the light will blink green.
Cables in the bottom row should be inserted up side down in relation to the how the
cables are inserted in the top row.
To remove, disengage the locks and slowly pull the connector away from the port receptacle. The
LED indicator will turn off when the cable is unseated.
