You are here to route FC-AL cables from Rack-2, Rack-3, Rack-4, or Rack-5 to the existing
storage facility.
About this task
Note: If an FC-AL cable is
damaged, you can use the point-to-point cabling diagrams to determine the other end of the cable.
See Point-to-point cabling diagrams - FC-AL, Flash PCIe, and SAS cables. Several FC-AL cables are tightly bundled together so
it is difficult to physically trace an individual FC-AL cable from end to end.
Procedure
Find and uncoil the FC-AL cables
that are coiled at the rear of the expansion rack you are installing.
Do not remove the black protective cable connector covers.
Determine the destination rack and storage enclosure for each FC-AL cable.
Find the location code label at the free end of each FC-AL cable.
Translate the location code to the destination storage enclosure, then go to step 3.
If the labels include the physical location code, such as R2-G01-P1-C1-T2, refer
to the following figures.
Figure 1. Cable labels, storage and I/O
enclosure locations for physical location codes

Route the FC-AL cables to the destination rack.
Do not connect the FC-AL cables to the storage enclosure Fibre Channel interface cards
until directed later in this procedure.
Route each cable bundle 1 to the destination rack through the rack
to rack holes at the upper rear of each rack. See Figure 6 and Figure 7.

If you are connecting cables to I/O enclosure locations, route the FC-AL cables to the
destination I/O enclosures.
Do not connect the FC-AL cables to the I/O enclosure device adapter cards until directed later
in this procedure.
FC-AL cables that will connect to an I/O enclosure on the left side of the rack are routed down
the left side of the rack.
Left side cables have "XI1" or "XI3" in the location code (for example, Rx-XI3-P1-Cx-Tx), or the
second character in the connection designator is uppercase (for example, 2A1).
FC-AL cables that will connect to an I/O enclosure on the right side of the rack are routed
down the right side of the rack.
Right side cables have "XI2" or "XI4" in the location code (for example, Rx-XI4-P1-Cx-Tx), or
the last character in the connection designator is lowercase (for example, 2a1).
If you are connecting cables to storage enclosure locations, route the FC-AL cables
to the destination storage enclosures.
Do not connect the FC-AL cables to the storage enclosure Fibre Channel interface cards
until directed later in this procedure.
FC-AL cables that will connect to the Fibre Channel interface card in
the left side of a storage enclosure are routed down the left side of the rack.
Left-side cables have "C1" in the location code (for example, R3-G05-P1-C1-T1), or the
last character in the connection designator is odd (for example, 2A5).
FC-AL cables that will connect to the right Fibre Channel interface card in a
storage enclosure are routed down the right side of the rack.
Right-side cables have "C2" in the location code (for example, R3-G05-P1-C2-T1), or
the last character in the connection designator is even (for example, 2A6).
Do not remove the black rubber protective connector covers at the end of each cable. Do not
connect the cables until directed later in the installation.
Find the expansion rack that you are installing in the first column of the following table and
then use the second column to continue the installation.
