Remote access via Ethernet or Modem:
Remote access to console switch and to the target systems is via a Web browser. The switch provides
agentless remote control and access. No special software or drivers are required on the attached servers
or client. Access is normally via a standard Ethernet network, requiring that the console switch be
connected to the network via one or both Ethernet ports. Connecting both ports provides redundancy.
Additionally, if a modem is connected to the modem port on the console switch and the modem is
connected to a telephone (PSTN) system, then you can dial the console switch via your modem and
establish an out-of-band connection to the console switch using the Point-to-Point Protocol (PPP) for
remote control. V.34, V.90, or V.92 connections are supported.
Conversion Options:
These are cable-connector combinations that are connected between the CAT-5 cables from the console
switches to the target systems. Figure 4 shows the five conversion option cables available for use with the
console switches. The part numbers are listed in Table 1.
The KVM Conversion Option (KCO) is suitable for target servers with VGA and PS/2-style mouse and
keyboard connections. The USB Conversion Option (UCO) is for systems with VGA and USB connections.
The Virtual Media Conversion Options (VCO and VCO2) supports the virtual media capability of the console
switches; however, they do not support chaining. We describe both virtual media and chaining later in this
document.

The built-in memory of each connection option helps simplify configuration by assigning and retaining
unique server identification codes for each attached server. This integrated intelligence enhances security
and helps prevent unauthorized access to a server through cable manipulation. The connection option is
powered directly from the server, providing Keep Alive functionality even if the server is not powered on.
Supported video resolutions are listed in the following table.
