Connecting SAS cables and power cords
Overview
Connecting cables includes the following steps:
1. Reading the Cabling best practices , page 35.
2. Connecting SAS cables to the server or controller enclosure , page 36.
3. Connecting SAS cables to cascaded disk enclosures , page 37.
4. Connecting power cords , page 38.
IMPORTANT:
The following illustrations demonstrate connecting a disk enclosure to a server with an installed
controller. In your environment, the disk enclosure might connect to a controller enclosure, which then
connects to the host or network. Cabling restrictions may exist for the different installation environments.
For more information, see the user documents for your controller or controller enclosure.
NOTE:
For additional examples of cabling scenarios, see Chapter 7 on page 45.
Cabling best practices
• Use supported SAS cables and power cords. A variety of cables and cable lengths are supported
for use with this disk enclosure. For more information, see the QuickSpecs for the disk enclosure,
available on the D2000 website:
http://www.hp.com/go/D2000 .
• Use the shortest possible cable between devices. Shorter cables reduce the possibility of signal
degradation that might occur over longer distances. In addition, shorter cables are easier to
manage and route along the back of the rack.
• Gather cables in the rear of the disk enclosure to ensure that the cabling in the back of the rack
system does not interfere with system operation or maintenance. Bind cables loosely with cable
ties and route the cables out of the way, along the side of the rack. When the cables are tied to-
gether and routed down the side of the rack, system components and indicators are easily visible
and accessible.
• Bind and support cables in a manner that eliminates stress on connectors and tight bends of the
cables. This prevents damage to the connector and cable, and ensures that the connector remains
fully seated in the port.
• Attach a label near both ends of each cable to identify the device connected to that cable. Include
the device, device name, port, or other useful information.
• Use colored markers to color code both ends of each cable, to help visually identify a particular
cable without having to read or locate the label.
• In multipath configurations, you might want to loosely bind the matching pair of cables connecting
devices.
