3.0System Components

Each ConsoleServer 3200 consists of three major components: chassis, device cards, and access cards.

3.1Chassis

The chassis contains a front-panel LCD for quick system information that is available at all times. Two front panel buttons allow display selection and paging through displays (see section 10.0 for more information). The second component of the chassis is the power supply module. This module contains two independent supplies, each capable of sustaining the system should one supply fail. The third and last component of the chassis is the switch and control card set. The switch cards connect the access cards to the device cards, with a maximum of 17 simultaneous connections using all available terminal, network, and modem ports.

3.1.1 Power Supply Module

The ConsoleServer 3200 may be equipped with either an AC power module or a DC power module. The power module may be changed if the available power source changes.

3.2Device Cards

Each device card has four completely independent ports for attachment to servers or other devices with console ports. Eight device cards may be installed per unit, for a maximum of 32 device ports. The device ports do not send a break to the attached servers at any time unless specified by the user. There are no adjustments directly on the device cards. All parameters are set up through the system administrator port.

3.3Access Cards

3.3.1 Terminal Cards

The terminal card provides a point of connection for a conventional terminal or a computer running a terminal emulation program. Users connected through a terminal card may connect to any of the device cards in the system, provided that their user profile has access rights for the port. There are four ports per terminal card. Each port‘s parameters are set up independently from the other ports. All parameters are set up through the system administrator port. There is no access to the administration functions through the terminal card.

3.3.2 Network Cards

The network card allows users to connect to the device cards from a telnet session over a network, and remote access to the administration functions. Each card supports four simultaneous user telnet connections and one administrator connection to the same IP
