SAN Director installation guide 61
A minimum length is required for cables that connect the 4/256 SAN Director ports to device ports,
as described in Table 9:
Setting initial configuration parameters
The 4/256 SAN Director must be configured before it is connected to the fabric, and all of the
configuration commands must be entered through the active CP card. The 4/256 SAN Director
configuration includes the following parameters:
• IP address and subnet mask for the chassis
• IP addresses, host names, subnet masks, and gateway addresses for both CP cards
• Director name
• Domain ID for the Director (optional)
• WWN for the Director
The Director WWN is initially set by the factory to match the license ID (which is based on the
chassis serial number). The WWN can be changed but the license ID cannot be modified.
The configuration information is automatically mirrored to the standby CP card—allowing the most
current configuration to remain available even if the active CP card fails. The configuration
information for the switch is stored in the WWN card and the flash memory of the CP cards. The
configuration can be backed up to a workstation (uploaded) and then downloaded to the active CP
card if necessary.
