To connect cables and power cords:
1. Read the cabling best practices.
2. Attach Fibre Channel, SAS, and/or LAN cables to controllers, drives, and servers.
3. Label all cables using the supplied cable labeling kit.
4. Plug in all power cables.

Cabling best practices

Use the shortest possible cable between devices. Shorter cables are easier to manage and
route along the back of the rack. In addition, shorter cables reduce the possibility of signal
degradation that may occur over longer distances.
Gather the cables in the rear of the array to ensure that the cabling in the back of the rack
system does not interfere with system operation or maintenance. Bind the cables loosely with
cable ties and route the excess cables out of the way, along the side of the rack. When the
cables are tied together and routed down the side of the rack, system components and
indicators are easily visible and accessible.
Attach a label near both ends of each cable to identify the device connected to that cable.
Include the device type, device name, port, or other information that you think will be helpful.
Use colored markers to color code both ends of each cable, to help you visually identify a
particular cable without having to read or locate the label.
In multipath configurations, you may want to loosely bind the matching pair of cables
connecting devices.

Connecting cables

To connect the EVA to the SAN, use standard Fibre Channel and/or SAS cables, observing the
following caution for good cabling-handling practices.
CAUTION:
Touching the end of a cable will either damage the cable or cause performance problems,
including intermittent difficulties accessing the storage.
Whenever a cable is not connected, replace the protective covers on the ends of the cable.
Make certain that the cables are installed and supported so that no excess weight is placed
on the connectors. This prevents damage to the connector and cable. Excess cable should be
loosely coiled and tied out of the way, being careful not to coil the cable in a tight loop.
The minimum bend radius is 25 mm for 50, 62.5, and 9 micron fiber optic cable. The bend
radius for the 0.5 meter SAS cable is 33 mm (1.3 inches); for the 2 meter SAS cable, it is
40.6 mm (1.6 inches).
