For most companies, the performance of IT equipment is critical to daily operation. To keep a server, router, PBX, or leased-line modem working properly, it is important to minimize downtime and troubleshoot faulty devices quickly. KVM is commonly used for in-band management of devices that are equipped with a screen and keyboard. However, RS-232 console access is often used as a last resort for all devices.
The CN2510 provides an easy console management solution in a convenient 1U rackmount package. With its RS-232 ports, connections are easily established to the console ports of network equipment, such as UNIX servers or routers, for centralized management of the attached devices. Each device’s RS-232 console port becomes a network-accessible node, giving users Telnet access from anywhere on the network for configuration and management of the device. Full modem control signals are supported, ensuring compatibility with a wide range of serial peripherals.
It is very important that access is strictly controlled in a console management solution, and user privileges should be validated before a console port connection is allowed. The CN2510’s authentication procedure involves verifying the username and password against an internal database or a RADIUS server.
When a dial-up connection is used for out-of-bandmanagement, the CN2510 provides a convenient dial-back function. Insteadof accepting a connection request directly, the CN2510 calls backthe management host to establish the connection. The dial-back functionhelps ensure that only registered users or hosts can remotely connectto the network through the CN2510, and helps to minimize long-distancephone costs.
