Use these three commands to configure network settings. Text in italics indicates a variable. For each variable, type a numeric value that has the format xxx. For example, to set a system IP address of Type exit.
The Rack PDU restarts to apply the changes. You can use a local computer a computer that connects to the Rack PDU or other device through the serial port to access the command line interface. Select a serial port at the local computer, and disable any service that uses that port.
If you are unable to display the User Name prompt, verify the following:. Press the Reset button. The Status LED will flash alternately orange and green. Press the Reset button a second time immediately while the LED is flashing to reset the user name and password to their defaults temporarily.
Press E NTER , repeatedly if necessary, to display the User Name prompt again, then use the default, apc, for the user name and password. If you take longer than 30 seconds to log on after the User Name prompt is re-displayed, you must repeat step 5 and log on again. At the command line interface, use the following commands to change the User Name and Password settings, both of which are now apc :.
For example, to change the Administrator user name to Admin , type:. Type quit or exit to log off, reconnect any serial cable you disconnected, and restart any service you disabled. Note: Your APC product is configured so the display backlight turns off after 10 minutes of inactivity.
The backlight can be turned on by depressing any button below the display. At least one load warning alarm is present, but no critical alarms are. In addition, the command line interface enables you to create scripts for automated operation. An Administrator has full access to the command line interface, a Device user and Outlet User have limited access, and a Read-Only user is completely restricted. To access the command line interface, you can use either a local serial connection or a remote Telnet or SSH connection with a computer on the same network as the Rack PDU.
You can access the command line interface through Telnet or SSH. Telnet is enabled by default. Enabling SSH disables Telnet. To enable or disable these access methods, use the Web interface. On the Administration tab, select Network on the top menu bar, and then the access option under Console on the left navigation menu.
Telnet for basic access. Telnet provides the basic security of authentication byuser name and password, but not the high security benifits of encryption. If the Rack PDU uses a non-default port number from to , you must include a colon or a space, depending on your Telnet cliet, between the IP address or DNS name and the port number. These are commands for general usage.
Some clients do not allow you to specify the port as an argument and some types of Linux might want extra commands. Enter the user name and password by default, apc and apc for an Administrator, or device and apc for a Device User. SSH for high-security access. SSH encrypts user names, passwords, and transmitted data.
The interface, user accounts, and user access rights are the same whether you access the command line interface through SSH or Telnet, but to use SSH, you must first configure SSH and have an SSH client program installed on your computer. For local access, use a computer that connects to the Rack PDU through the serial port to access the command line interface:. Select a serial port at the computer and disable any service that uses that port.
Run a terminal program e. At the prompts, enter your user name and password.

Feature Overview Basic Installation Rack Mount Installation Advanced Installation Keyboard Control Keyboard Switching Activating OSD The OSD Window The Command Menu Basic Channel Maintenance The ID Window Administrator Functions Choosing a Scanning Method Setting the Scanning Order Turning Scanning On and Off Setting the Scanning Dwell Time Scanning and Security Problem Report All rights reserved; reproduction in whole or in part without permission is prohibited.
Each computer can be up to 25 feet away from the switch. If more than eight channels are needed, multiple units can be cascaded together for expansion. Up to 2 tiers of units can be connected for a total of 64 attached computers in one system. Name your computer channels anything you wish, then select the desired computer from an easy-to-use menu. Secondary menus let you configure and initiate channel scanning and other system features. Use the advanced two-level security feature to configure and control server access for every type of user in the system.
The OSD Configuration Utility allows the administrator to easily configure and download a channel list with defined users and access privileges to the entire system. This utility will also read and save your current configuration for extra security.
In addition to using the on-screen menus, you can switch computer channels in one of three easy ways: via the APC KVM Switch channel push-buttons, with the Scan button or with a simple keyboard sequence. This prevents attached computers from locking up and keeps you from losing time and data. A built-in scanning feature allows you to automatically monitor, or scan, your computers without intervention. When keyboard activity is detected, scanning is suspended until all activity stops.
Scanning then resumes with the next channel in sequence. Status, scanning and channel LEDs take the guesswork out of system operation and diagnostics. The following mice are known to be compatible:.
If you experience problems using an untested mouse, contact APC Technical Support with the manufacturer and model number of the mouse in question. Plug your VGA monitor cable into the port on the back of your.
Locate your first input cable. Plug this cable into any numbered channel port on the rear of the switch. Plug these connectors into the matching ports on your computer. Locate your next input cable. Repeat step 4 until all computers are properly attached to the switch. Plug it into the IEC power connector on the switch.
This outlet must be near the equipment and easily accessible, to allow for unplugging prior to any servicing of the unit. Always disconnect the power cord from the electrical socket. Remove the side screws that secure the cover on your KVM Switch. Line up the holes in the side brackets with the screw holes in the side of the KVM Switch unit.
Using the previously removed screws, thread one through each of the holes in the sides of the rack mount brackets and into the KVM Switch cover. Tighten them securely. Follow steps of the Basic Installation section. Plug the pin video connector on the other end of the cable into. Plug the remaining 6-pin miniDIN keyboard connector into the port. Repeat steps for every cascaded switch unit in your system. Power-up your switch unit s first, then all attached computers.
All units ship defaulted to the non-secure mode. Computers may be powered-up one-at-a-time or all at once. No operator intervention is required during booting.
