Configuration overview The Core Switch 2/64 includes two logical switches in one cabinet. Each switch can have up to 64 ports. The SAN Director 2/128 is a single switch in one cabinet. It can have up to128 ports. This section provides information about how each switch is configured. Core Switch 2/64 The Core Switch 2/64 can contain up to two logical switches, each with its own configuration: one logical switch for any 16-port cards in slots 1-4, and one logical switch for any 16-port cards in slots 7-10. The configuration information for both logical switches is stored in the WWN card and in the CP cards' flash memory. The configuration settings are automatically mirrored to the standby CP card. In this way, the most current configuration is available even if the active CP card fails. You can also back up the configuration by uploading the settings to a workstation using the configUpload command (see "Backing up system configuration settings" on page 131), and you can download the settings to the active CP card using the configDownload command (see "Restoring the system configuration settings" on page 132). NOTE: HP recommends a routine backup of the configuration to ensure that the current configuration is available if it is needed. The Core Switch 2/64 configuration can be modified only through a login session to the active CP card. The switch supports up to two simultaneous telnet sessions (with administrative privileges). NOTE: For fabric OS v4.1 or later, different logins are provided for each logical switch. Logical Switch 0 has logins User0, Admin0, Factory0, and Root0. Logical Switch 1 has logins User1, Admin1, Factory1, and Root1. For versions earlier than v4.1, the same administrative login account applies to both logical switches. If the password is changed on switch 0, it is automatically changed on switch 1. 52 Installing and configuring the switch
