6 Configuring Cyber Breaker the Virtual Circuit Breaker In addition to the optional hardware circuit breakers for each bank of outlets, the ePower PDU provides an adjustable Virtual Circuit Breaker for each outlet, known as a Cyber Breaker® the Virtual Circuit Breaker™ (referred to as “Virtual Circuit Breaker” or “VCB” within in this user manual and the Web interface).
Chapter 6 – Configuring Cyber Breaker the Virtual Circuit Breaker Theory Each Virtual Circuit Breaker operates according to a trip-curve equation that relates actual current to trip delay time, resulting in the following features: • Limits over-current conditions to a single outlet • Turns Off an outlet when the amperage exceeds a user-defined threshold • Decreases trip delay time as current increases A Virtual Circuit Breaker behaves according to the following algorithm: • From 0A to the user-defined curr
Chapter 6 – Configuring Cyber Breaker the Virtual Circuit Breaker Trip Delay Curve Equation The trip delay curve equation for tdelay (represented by the function f(x)) for any given current (x) above Imin is: where variables a, b, c, and d are as described in Table 6-1. [ ƒ (C) = a • e Table 6-1 Variable -b( C - c ) ]+ d Trip Delay Curve Equation Variables Description a = tgrace Maximum tdelay at Imin Default Value 400 sec b Curve “slope” constanta 0.
Chapter 6 – Configuring Cyber Breaker the Virtual Circuit Breaker Example 1 In this example, a Virtual Circuit Breaker is configured on an IEC 60309 C19 outlet, with a maximum current rating of 20A. The trip delay starts at 7 seconds (a=7) at 4A (c=4, the breaker trip value), and decreases until it reaches 2.5 seconds (d=2.5) at 20A. Above 20A, the trip delay is 0 seconds. The equation for the Example 1 trip delay curve under 20A is: [ ƒ (C) = 7 • e Figure 6-1 58 -0.3 3 3( C - 4) ]+ 2 .
Chapter 6 – Configuring Cyber Breaker the Virtual Circuit Breaker To configure a Virtual Circuit Breaker to the same settings as Example 1, set the parameters in the Web interface: 1. On the Home page, select the bank and outlet for which you want to set a Virtual Circuit Breaker: 2. In the Outlet Options > Alerts tab, select Enabled under Virtual Circuit Breaker, then enter the appropriate values for the Threshold, Max. Grace Period, Min. Grace Period, and Curve Constant, as shown: 3. Select Save.
Chapter 6 – Configuring Cyber Breaker the Virtual Circuit Breaker Example 2 In this example, a Virtual Circuit Breaker on a 20A-rated outlet starts with a trip delay of 400 seconds (a=400) at 16A (c=16, the breaker trip value). The trip delay decreases until it reaches zero seconds at 34A or greater. A negative tmin value (d=-1.81) is used to fine-tune the trip curve to a zero crossing at 34A. The equation for the Example 2 trip delay curve is: [ ƒ (C) = 4 0 0 • e Figure 6-2 60 ] - 1 .8 1 -0.
Chapter 6 – Configuring Cyber Breaker the Virtual Circuit Breaker To configure a Virtual Circuit Breaker to the same settings as Example 2, set the parameters in the Web interface: 1. On the Home page, select the bank and outlet for which you want to set the Virtual Circuit Breaker: 2. In the Outlet Options > Alerts tab, select Enabled under Virtual Circuit Breaker, then enter the appropriate values for the Threshold, Max. Grace Period, Min. Grace Period, and Curve Constant, as shown: 3. Select Save.

7 Troubleshooting General Questions The following table describes how to resolve common issues that may be encountered when using the ePower unit. If the suggested solutions do not resolve the problem, contact Cyber Switching’s Technical Support at support@cyberswitching.com. For additional support information, visit www.cyberswitching.com/ epower/support.
Chapter 7 – Troubleshooting Issue Suggested Solution What is the ePower Reboot sequence? When you Reboot an outlet, the outlet immediately turns Off, then turns back On, after the Off-to-On timer expires. The default Off-to-On delay time is five seconds. The delay time can be changed in the Outlet Properties dialog box, in the Web interface.
Chapter 7 – Troubleshooting Issue Suggested Solution This message indicates that JFFS2 has detected a bad NAND block and corrected the problem. NAND flash commonly wears down over time. The ePower implements “wear leveling,” which significantly reduces the chances of this occurring. The message Erase at XXXX failed immediately, followed by JFFS2: marking eraseblock at XXXX as bad. appeared in the system log.
Chapter 7 – Troubleshooting Issue I occasionally see the message TX underrun, resetting buffers in the ePower’s data logs. Is this an issue? On my ePower unit, why does the alert settings icon column appear to flicker? Suggested Solution This is a common house-cleaning message sent by the kernel, when the network transmit buffers are flushed. It can be safely ignored, and is a common Linux notification for embedded systems.
Chapter 7 – Troubleshooting Restoring Factory Default Settings To reset the ePower to factory defaults: 1. Connect an RS-232D serial cable to the ePower unit’s RS-232 serial port, and open a terminal emulation program, as described in the Initially Configuring the RS-232 Serial Port to Use the CLI section in Chapter 2, “Installing the ePower PDU.” 2. Using a firm, thin object (such as the end of an unfolded paper clip), press and hold the reset button for 1 to 2 seconds. 3.
Chapter 7 – Troubleshooting Troubleshooting a Tripped Outlet (Virtual Circuit Breaker) After a Virtual Circuit Breaker is properly configured, any “trip” conditions should be properly investigated before resetting the circuit breaker’s state. Constantly toggling the relay state from Tripped to Off to On without first clearing the condition that caused the trip causes the relay to trip again. If the trip occurs at a high amperage, this can reduce the lifetime of the relay.
Chapter 7 – Troubleshooting Resetting the ePower PDU Resetting the ePower PDU performs a hardware reset of the internal Network Interface Card (NIC) in the event of a lock-up. The reset button is located beside the RS-232 serial port, through the access hole (refer to Figure 7-1). Figure 7-1 Reset Button Location To reset the ePower PDU: 1. Using a firm, thin object (such as the end of an unfolded paper clip), press and hold the reset button for 1 to 2 seconds.

Appendix A – CLI Command Reference cd Syntax cd [target] Description Changes the current default target. By default, the current default target is /. To change the target, issue the “cd target” command. target must be an element that is “adjacent” to the Current Target Element in the nested hierarchy shown in the ePower CLI Managed Elements Hierarchy section.
Appendix A – CLI Command Reference Example 2: Change the Current Target Element from /system1/settings/interfaces to http. ePower:/system1/settings/interfaces--> cd http ePower:/system1/settings/interfaces/http--> Example 3: Use cd, without specifying an explicit target. ePower:/system1/settings/interfaces/http--> cd ePower:/system1/settings/interfaces/http--> Example 4: Change the Current Target Element, using UNIX file path notation. ePower:/system1/settings/interfaces/http--> cd .
Appendix A – CLI Command Reference commit Syntax commit [target] Description Sets and updates a section of properties within a managed element, specifically for network settings where all values need to be updated with a single command; otherwise unexpected behavior might occur. The elements that support commit are /system1/settings/network and /system1/settings/interfaces/energywise. Response There is no response for the commit command.
Appendix A – CLI Command Reference exit Syntax exit Description Terminates the ePower CLI process. The supported synonyms are: • Ctrl-C (Break) • Ctrl-D (End-of-File) Example 1: Terminate the current CLI session. ePower:/--> exit …[session disconnected]… Response The ePower login message is displayed. 78 ePower Power Distribution Unit User Manual, Revision 1.
Appendix A – CLI Command Reference help Syntax help [options] [target] [properties] Description Displays information regarding how to use the ePower CLI. If help is issued with no options, then a summary of this section is displayed. Options • –cd – Provides help for the cd command. • –commit – Provides help for the commit command. • –exit – Provides help for the exit command. • –reset – Provides help for the reset command. • –set – Provides help for the set command.
Appendix A – CLI Command Reference Response Paragraph-formatted text from the CLI specification. help with no options returns a summary. Example 1: Display help for the show command. ePower:/--> help –show show [] [] [][propertyname==propertyvalue] -d, -display Display the parts of the element, where parts are (targets, properties, verbs, all). The default value is all. [Remainder of response not shown.] Example 2: Display help for the IPv4 target.
Appendix A – CLI Command Reference reset Syntax reset reload reboot Description Restarts the device, from boot-up; performs a warm-boot. This has almost the same behavior as toggling the power, except the outlets are unaffected during this process. This command is valid only at the system element. CAUTION Use this command with caution, because it is a system reset. Response There is no command response for the reset command. ePower Power Distribution Unit User Manual, Revision 1.
Appendix A – CLI Command Reference set Syntax set [target] propertyname=value Description Sets the value of properties in a managed element. If no target is specified, the current working target is used. Properties • propertyname=value Sets the property for the given target. Accepts a line with multiple property names and values, separated by spaces. For Boolean properties, accepts Y, Yes, True, or On, and N, No, False, or Off, but displays Y and N. Response There is no response for the set command.
Appendix A – CLI Command Reference show Syntax show [options] [target] [properties] [propertyname==propertyvalue] Description Displays the contents of a target. If no target is specified, the current default target is used. Options • -d, -display properties Displays output that matches the indicated property type(s) (targets, properties, verbs, all), where all is the default if omitted. • -l, -level value Restricts the output to value levels deep in the hierarchy. The keyword all can be used for value.
Appendix A – CLI Command Reference Response If show is issued with no options, all elements (targets, properties, and verbs) for the specified target are displayed. The output format is as follows: [Fully Qualified Target Address] Targets: [Target 1] [Target 2] […] [Target L] Properties: [Property 1] = [Value 1] [Property 2] = [Value 2] [Property 3][0] = [value 3.0] ** when property is a list [Property 3][1] = [value 3.
Appendix A – CLI Command Reference Example 1: Show all elements in the current default target. ePower:/--> show / Targets: session system1 Properties: [None] Commands: cd show help ePower:/--> When show is used with options other than all, such as –d properties, the output format is the same as above, with the other elements omitted. Example 2: Show the properties in the IPv4 target. ePower:/--> show -d properties /system1/settings/network/ipv4 /system1/settings/network/ipv4 Properties: address = 10.0.3.
Appendix A – CLI Command Reference Example 3: Recursively show the available commands for the network target. ePower:/--> show –l all -display verbs system1/settings/network /system1/settings/network Verbs: cd show set help /system1/settings/network/ipv4 Verbs: cd show set help /system1/settings/network/ipv6 Verbs: cd show set help ePower:/--> Example 4: Show only properties with the name “address”.
Appendix A – CLI Command Reference version Syntax version Description Displays current version information for the ePower firmware. Response Returns the ePower firmware version information. Example 1: Display the current firmware version (where YYYY is the year of release and RR is the number of the release (01, 02, 03, and so forth) within that year). ePower:/--> version Software Version: csLinux YYYY.RR ePower Power Distribution Unit User Manual, Revision 1.
Appendix A – CLI Command Reference ePower CLI Managed Elements Hierarchy This appendix documents the ePower managed elements, which use a tree structure for the grouping of elements within branches. All elements are under “/” (the root node). To reach a given element, specify one of the following: • Absolute path from the root • Relative path from the current working target Targets specify the managed element within the ePower CLI Managed Elements Hierarchy on which a verb operates.
