Connectors on the AlterPath OnSite

AlterPath OnSite Administrators and Users Guide
Serial Ports
Serial ports provide remote access to many types of devices that have console
ports.
Servers running Linux, FreeBSD, Solaris, HP/UX, AIX, System V, or other
UNIX operating systems, or Microsoft Windows 2003 with emergency
management services (EMS) enabled can be managed over their console ports
(or serial ports configured as console ports). Through their consoles, you can
get low-level control over servers, with access to hardware self-test and BIOS
information that is generated before the operating system is loaded and that is
therefore not available over the network. Other types of equipment, such as
routers, hubs, switches, modems, POS (point-of-sale) systems, PBXs, ATMs,
process controllers, and environmental monitoring devices, also have console
ports or auxiliary ports that you can connect to the OnSite serial ports for
similar purposes.
When a device is connected to an OnSite serial port, you can access diagnostic
information (boot messages, error logs, alarms, monitor mode), change low-
level system configuration and perform and script other administrative tasks,
such as resetting or rebooting the system. You can receive notifications via
email, pager, or SNMP trap if a device crashes or other event of interest
occurs. You can directly connect to the serial ports via telnet, ssh, or other
connection protocols. You can also connect to the serial ports through the Web
Manager.
You can also connect dumb terminals to serial ports. You can dedicate a dumb
terminal to a single remote server or you can enable the dumb terminal to
access many servers through the OnSite. When configuring a dumb terminal
as a local terminal that uses telnet or ssh to access the OnSite, you can
define a command menu that appears when the dumb terminal is turned on.
The OnSite is usually connected to the serial port of a device using a RS-232
cable with a DB-9 connector on the OnSite end.
KVM Ports
The KVM (keyboard, video, mouse) ports provide remote access to the
keyboard, monitor, and mouse devices of servers running Microsoft
Windows, Sun Solaris and Linux operating systems. Connecting a server to a
KVM port allows use of a keyboard, video, and mouse on a remote work
station as if it were the keyboard video and mouse of the connected server.
