Remote Console Management
Remote Console Management provides system
administrators with an efficient means of setting up and configuring
network devices—over a TCP/IP Ethernet or by telephone through
a modem-to-modem connection.
Console Management makes use of a product's console port to provide
basic setup and maintenance capability for a wide range of networking
devices. And although this option has been available since at
least the 1970's, it still provides one of the most efficient
means of managing large numbers of networking devices, particularly
when used in conjunction with a reliable Console Server.
A Console Server is a specialized network computer that has at
least one Ethernet port, and multiple serial ports, providing
the capability of using only one TCP/IP network host to simultaneously
connect to the console ports of several devices. Centralized console
control is generally achieved using Telnet through an Ethernet
LAN/WAN connection. To serve as a backup when the Ethernet connection
is unavailable, most Console Servers also provide for a direct
telephone hookup using one modem with the administrator's computer,
and a modem connected to one of the Console Server's serial ports.
Centralized Console Management
Async Server is a sophisticated network device server with its
own built-in NIC (Network Interface Card) and unique IP address.
The primary method of implementing Remote Console Management is
to telnet to Async Server over an Ethernet LAN/WAN/Internet connection.
Each of the attached devices is associated with a unique TCP socket
number, allowing the system administrator to establish a direct
connection between his own computer and each device.
Remote Access Solution
An important aspect of Async Server's operation is that it can
be used as a dial-in/out server, allowing a remote administrator
to access all console management functions from a private PPP
connection (i.e., there's no need to go through an ISP), provided
a modem is connected to one of Async Server's serial ports. In
fact, with the scheme illustrated in the figure above, there would
be no need to obtain a public IP address for Async Server, since
using Async Server's dial-in function provides remote access to
your own private LAN.
A Robust Connection Scheme
Async Server's dial-in capability also allows it to overcome
one of the problems inherent in a pure network management device.
That is, what should be done if the WAN/Internet connection goes
down, taking the connection to the management device with it?
This is particularly true if you are accessing Async Server over
a WAN or over the Internet. Making use of Async Server's dial-in
capability provides access to all console management functions
from a private PPP connection, giving a system administrator the
ability to fix serious network problems, and get the Ethernet
connection up and running in good time.
Complete IT Management Solution from Moxa
Combining MOXA NPower Commander with Async Server provides system
administrators with a complete Console Management and Power
OnOff solution that can be used with workstations, servers,
routers, and other similar equipment. By using Async Server and
NPower Commander together, system administrators not only have
access to centralized Console Management over an Ethernet, but
also have the luxury of being able to remotely OnOff the power
to the usual array of devices.
Advantages and Benefits
Moxa Async Server's console management capability provides system
administrators with an efficient and economical Remote Console
Management solution. Under normal operating conditions, a TCP/IP
Ethernet connection is used to perform basic setup and maintenance
of important networking devices, over a LAN, WAN, or Internet.
And Asyn Server's dial-in function can be used via a regular modem-to-modem
phone connection to access devices when the Ethernet is unavailable.
