3.0 System
Components
Each ConsoleServer 3200 consists of three major components: chassis, device cards,
and access cards.
3.1 Chassis
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.
3.2 Device
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.
3.3 Access
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

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
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
