6. Slide the gateway into the rails. This is easier with two people.
7. Make sure the gateway will be level after installation.
8. Put the gateway into place and screw the bolts into the nuts from step 5. Tighten the bolts to 9.2
Nm or 81.5 pound inches.
9. Tighten the pan head screws, from step 4 that hold the rails, to 9.2 Nm or 81.5 pound inches.
10. Ground the gateway.
You must install an external ground to all IT components. If this gateway is installed in a grounded rack,
make sure the gateway chassis has a valid connection to the rack. If the gateway is not installed in a
grounded rack, 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.
11. Plug in the power cables.
Note: There is no On-Off switch on the gateway. The gateway will come on when the plug is plugged in.
12. Check the Status LEDs and confirm that all of the LEDs show status lights consistent with nor-
mal operation.
13. You can start connecting all of the cables to the gateway.
Cable Installation
All cables can be inserted or removed with the unit powered on. To insert a cable, press the connector into
the port receptacle until the connector is firmly seated. The GREEN LED indicator, above of each CX4 ports
or above or below each SFP+ 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 mechanism particular to
the cable vendor. When a logical connection is made the yellow light will come on. When data is being
transferred the yellow light will blink.
Note: When installing SFP+ cables make sure that you hear a click when the latch engages.
Always install and remove cables by pushing or pulling the cable and connector in a straight line
with the gateway.
To remove, disengage the locks and slowly pull the connector away from the port receptacle. Both LED
indicators will turn off when the cable is unseated.
Care should be taken not to impede the air exhaust flow through the ventilation holes next to the InfiniBand
ports. Cable lengths should be used which allow for routing horizontally around to the side of the chassis
before bending upward or downward in the rack.
Cables in the bottom row should be inserted up side down in relation to the how the cables are inserted in the
top row.
Warning: Any yellow status LEDs is cause for concern and must be dealt with
immediately.
Cables, especially long copper cables, can weigh a substantial amount. Make
sure that the weight of the cable is supported on its own and not hanging from
the gateway.
