Grounding Issues
007-4522-003 37
This transparent flexibility protects investments in existing infrastructure, enhances
storage area network (SAN) robustness, and simplifies SAN configuration management.
The 2Gb TP9100 with FFx-2 RAID controller features a host side hub function which is
configured by the switches on the ops panel. When the system is in hub mode, FC-AL is
the only supported topology. If the system is in point to point mode because of the host
hub functionality, the system must be power cycled before connecting to a HBA or switch
in an arbitrated loop topology.
For more information on configurations, see “Disk Topologies” on page 65.
Grounding Issues
Each chassis—storage or host—must be well-grounded through its power connector. If
you have any doubts about the quality of the ground connection, consult with a qualified
electrician.
The branch circuit wiring should include an insulated grounding conductor that is
identical in size, insulation material, and thickness to the earthed and unearthed
branch-circuit supply conductors.
The grounding conductor should be green, with or without one or more yellow stripes.
This grounding or earthing conductor should be connected to earth at the service
equipment or, if supplied by a separately derived system, at the supply transformer or
motor-generator set. The power receptacles in the vicinity of the systems should all be of
an earthing type, and the grounding or earthing conductors serving these receptacles
should be connected to earth at the service equipment.
Warning: The rack power distribution units (PDUs) must be connected only to
power sources that have a safe electrical earth connection. For safety reasons, this earth
connection must be in place at all times.
Connecting the Power Cords and Powering On the 2 Gb TP9100 Tower
The tower requires 115-220 V (autoranging), and is shipped with two power cords,
shown in Figure 2-1.
