Bundled cables can obstruct the movement of conditioned air around your storage
system.
■
Secure cables away from fans.
■
Keep cables away from the intake holes at the front of the storage system.
■
Use flooring seals or grommets to keep conditioned air from escaping through cable
holes.
Preparing for future maintenance
Design your cable infrastructure to accommodate future work on the storage system.
Give thought to future tasks that will be performed on the storage system, such as
locating specific pathways or connections, isolating a fault, or adding or removing
components.
■
Purchase colored cables or apply colored tags.
■
Label both ends of every cable to denote the port to which it connects.
Cable retention
Unintentional unplugging or unseating of a power cable can have a serious impact on
the operation of an enterprise storage system. Unlike data cables, power connectors do
not have built-in retention mechanisms to prevent this from happening.
To prevent accidental unplugging or unseating of power cables, the storage system
includes a rubber cable-retention strap near the AC receptacle on each controller. These
straps, shown in the following image, loop around the neck of a power cable connector,
and the notched tail is slipped over the hook of the restraining bar fixed to the storage
system.
AC power cables
Utility AC power standards for connector types and voltage levels vary by country. Hitachi
provides a variety of power cables that facilitate using storage systems around the world.
Hitachi power cables meet the safety standards for the country for which they are
intended.
