– Install one or more foam-block tailgate inserts into any open slot (refer to the tailgate illustration
above).
Note: Do not connect any HPS cables until instructed to do so.
After the preliminary steps are complete:
1. Sort the HPS cables into groups based on SNI port location, but do not clamp or connect cables until
instructed to do so. An overview of the next few steps is as follows:
a. Switch cables will be clamped into the tailgate in groups of either four or two.
b. High Power Switch cables get clamped into the next available tailgate slot.
c. Continue this cable pattern working down the frame and clamping to the right in the tailgate.
2. Before routing the switch cables, position the HMC, Ethernet, and I/O cables but do not clamp these
cables into the tailgate until instructed to do so.
a. Route the HMC and Ethernet cables to the appropriate connectors and connect each cable.
v
If present, make certain the HMC and Ethernet cables do not interfere with the SNI ports.
b. Wire tie the HMC and Ethernet cables into a bundle running down the side of the frame.
c. Wire tie any I/O cables into a bundle running down the side of the frame.
3. If HPS cables are present, without plugging the switch cables into the SNI ports, take the switch cables
and raise them into position.
a. Check any cable labels and verify that you have the correct cables for each SNI port.
b. Make certain that the cable for the upper SNI port extends further than the cable for the lower SNI
port.
c. Place a wire tie far enough down the cable set so that the cables will have sufficient length for a
gentle bend radius.
d. Wire tie the cables together.
4. Clamp any HPS cables into the next available tailgate slot using a rubber-faced, tailgate insert with the
appropriate thickness of rubber.
5. If they are used, clamp the I/O cables into the tailgate using tailgate inserts. Depending on the number
and size of the I/O cables, you may have to use one or two tailgate slots and clamping inserts.
6. Clamp the HMC and Ethernet cables into an available tailgate slot using a tailgate insert.
7. Insert foam-block tailgate inserts into any remaining tailgate slots.
If you have properly cabled the frame, the cable layout should look like the following illustration.
