• Power supplies The director contains two power supplies that share the electrical operating load. If one power supply fails, the other supply handles the full load. Separate receptacles at the rear of the director provide facility input power to each supply. For full redundancy, input power for each receptacle should come from a different source. • Fan modules The director contains two fan modules, each containing three fans (six fans total). If one or more fans in a module fail, the redundant fan module provides cooling until the failed module is replaced. If the second fan module fails, software shuts off power to the director to prevent system damage. • Ports The director is delivered with a minimum of eight FPM cards (32 ports). Any unused Fibre Channel port can be used in place of a failed port. To continue device operation, the fiber-optic cable from a failed port is reconnected to an unused operational port. Additional FPM cards (up to 16 total cards) can be installed to provide spare or additional Fibre Channel port connections. Connectivity Features The director and associated Product Manager application support the following Fibre Channel connectivity features: • Any-to-any connectivity Director software configures hardware routing tables for each source port to provide any-to-any port connectivity. Subject to user-defined restrictions (port blocking and zoning) the tables define the destination ports with which the source port is allowed to communicate. In addition, the director provides connectivity for OSI devices. • Port blocking System administrators can block or unblock any director port through the Product Manager application. Blocking a port prevents an attached device from logging in to the director or communicating with any attached device. A blocked port continuously transmits an offline sequence (OLS). 10 Director Features

one power supply fails, the other supply handles the full load. Separate receptacles at
the rear of the director provide facility input power to each supply. For full
redundancy, input power for each receptacle should come from a different source.

The director is delivered with a minimum of eight FPM cards (32 ports). Any unused
Fibre Channel port can be used in place of a failed port. To continue device operation,
the fiber-optic cable from a failed port is reconnected to an unused operational port.
Additional FPM cards (up to 16 total cards) can be installed to provide spare or
additional Fibre Channel port connections.
Connectivity Features
The director and associated Product Manager application support the following Fibre
Channel connectivity features:
•
Any-to-any connectivity
Director software configures hardware routing tables for each source port to provide
any-to-any port connectivity. Subject to user-defined restrictions (port blocking and
zoning) the tables define the destination ports with which the source port is allowed to
communicate. In addition, the director provides connectivity for OSI devices.
•
Port blocking
System administrators can block or unblock any director port through the Product
Manager application. Blocking a port prevents an attached device from logging in to
the director or communicating with any attached device. A blocked port continuously
transmits an offline sequence (OLS).
