______________________________________________________________________________

IV. INITIAL SET-UP

Device Management Utility (DMU)

The SurgeX Device Management Utility (DMU) provides the easiest means to find and configure your AR for use. The DMU can:

1. Automatically discover multiple ARs on a local network.

2. Display the current IP address of each AR.

3. Allow the setting of a new IP address for each AR.

4. Perform firmware upgrades.

5. Return an AR to Factory Defaults.

The SurgeX Device Management Utility is available on the SurgeX website at

http://www.surgex.com

Note: The IP address can only be set within the first 2 minutes after powering up the AR. The utility will only work with ARs on the same local subnet as the PC.

• Device

o Discover: Automatically discover all

ARs on the local network. The DMU will display the location name of the AR, the product ID and version number, the current IP address, and the MAC address. Factory defaulted ARs will display with the name Axess Ready and have an IP address that was automatically assigned by the DHCP server on your network.

- The IP address field also indicates the port for web access that is currently in

use by the AR. The standard port for web browser accessibility is factory default Port 80.

o Add: Manually add an AR by IP address. o Clear: Clear the list.

SA-20-AR User Manual

______________________________________________________________________________

• Manage

o Open Browser: Opens the web browser interface for the selected AR. o Upgrade Firmware: Starts the Firmware Upgrade dialogue.

Firmware Upgrade requirements:

- Valid firmware file.

- Administrative login credentials.

- “Upgrade Enable” must be set to yes, set via web page or CLI.

• Set

o IP Address: Changes the IP address of the selected AR. o Factory Defaults: Return the selected AR to a Factory Default state. This action must

be performed within the first 2 minutes after powering up the unit.

o Local Address: Select the IP address to Discover on. This may be necessary for

computers with multiple network connections.

• Exit

o Exits the DMU program.

• Help

o Online Help: Opens a web browser to online help resources. o About: Displays DMU version information.

Setting the IP Address

ARs are configured with a DHCP assigned factory default IP address.

To set the AR’s IP address using one of the following methods, the computer and AR must be on the same local network.

o DMU: Follow the steps in the preceding subsection to set the IP address using the

Device Management Utility (DMU).

o CLI: These are the basic commands to set the network parameters. After setting these

parameters, the AR will need to be rebooted for the settings to take effect. Any command that requires rebooting of the AR will provide a prompt to do so. All commands may be entered as required before rebooting. Manually specifying the IP address via CLI automatically sets the address as static.

SA-20-AR User Manual

______________________________________________________________________________

Example: Telnet to default IP address of 192.168.1.254 on default Port 23:

SurgeX Axess Ready v1.01.41 User> admin Password> *****

Axess Ready> set ipaddress 10.1.2.69

Ok Axess Ready Reboot Required> set subnet 255.255.255.0

Ok Axess Ready Reboot Required> set gateway 10.1.2.1

Ok Axess Ready Reboot Required> reboot

The CLI command set ipmode dhcp followed by a reboot command may be used to configure the AR to automatically acquire its network settings from a DHCP server. A DHCP server will automatically assign an IP address (dynamic address), as well as the Subnet Mask and Gateway.

To determine what IP address has been automatically assigned by the DHCP server, you will need to use the Discover feature of the DMU or query your DHCP server and locate the MAC address of the AR in the DHCP server’s IP/MAC table.

o Web: To set the IP address using a web browser, navigate to the current IP address of the

AR. Enter the administrator credentials (Factory Default User: admin, Password: admin), click on “Setup”, then click on “Network” and follow the directions in the Web Server/Network/Setup section of this manual.

SA-20-AR User Manual

______________________________________________________________________________

V. WEB SERVER

The Axess Ready web interface provides the easiest means of operating the outlet and changing configuration parameters.

To access the web interface, open a web browser and enter the IP address of the AR into the address bar.

Password

The AR uses two username/password credential sets, one for normal power control (user) and one that also provides access to the Setup functions (admin).

Default credentials:

Role

Username (fixed)

Password (user set)

Administrator

admin

User

user

Enter a valid username and password when prompted. When the proper username/password combination is received, the Control and Status Page is displayed.

Control and Status Page

Once a user is validated, the Control and Status page is displayed.

Note: Only one user may be logged in to the AR at a time.

Press “Power On” or “Power Off” to turn the AC output

On or Off. In the event of a power outage, the AC output will return to its last known state prior to the outage.

Press “Cycle Power” to temporarily change the state of the AC output for a specified cycle time

(factory default is 10 seconds). The cycle operation performed will either be On-Off-On or OffOn-Off, depending on the initial state of the AC output. During the power cycle operation, the Power Status bar will indicate the temporary status with a Blue background. Once the cycle is complete, the status bar will revert to its original condition. To abort a power cycle, press either

“Power On” or “Power Off” and the outlets will assume that status.

Use the Refresh button to update the page with the most current status. Use of the browser’s

refresh button may lead to inadvertent power switching. If an NTP time server is being used, the time of the last refresh will be displayed in the upper right corner, as well as a History log below the Power Status.

SA-20-AR User Manual

______________________________________________________________________________

Setup Pages

Setup pages are only available while logged in with Administrator credentials. Press Save to save the new settings. If the new settings require the AR to be rebooted, a Reboot button will appear at the bottom of the page. Settings requiring reboot will not take effect until the unit is rebooted.

o Device

• Location ID: Specifies a name label (up to 20 characters) that will be displayed at

the top of all pages. Assigning unique names is helpful for management of multiple units.

• Cycle Time: Specifies the length in seconds of a power cycle (1-999 seconds).

This is the amount of time the outlet will temporarily be On or Off, depending on the initial outlet state.

• Disable Off: When checked, removes the Power OFF button from the Status and

Control page.

• Upgrade Enable: Enables the ability to upgrade the firmware of the AR.

• Auto Logout: Specifies the inactivity timer duration in minutes (0-99 minutes). If

there is no activity after the specified amount of time, the user will be automatically logged out. Setting the timer duration to 0 disables the timeout feature.

• Enable Security Timeout: When unchecked, disables the 2-minute window for

setting IP address and factory defaults via DMU.

Important: As the AR allows only one web user logged in at any time, use caution when disabling the timeout feature, as it is possible to lock out other users by forgetting to log out. Closing the web browser will not log the user out and may lock out web access. In this situation it will be necessary to access the AR via telnet and reboot the unit.

SA-20-AR User Manual

______________________________________________________________________________

o AutoPing

The AutoPing feature allows the AR to automatically detect failed equipment and perform a timed reboot or other power control function (like turning on an indicator or siren). First specify one or two IP addresses to be periodically pinged. When the AR no longer receives a response from these addresses, the programmed power control function is actuated. AND or OR logic can be applied to the two addresses, so that both (AND) or either (OR) must fail in order to trigger the selected action.

Examples:

Server monitor: AR is installed with the device it monitors and automatically reboots if there is no response. Ideal for Kiosks and Servers.

Service monitor: AR is installed with the device to be rebooted but pings a remote host to test the communication channel. Ideal for DSL/Cable Modem verification.

AR monitors a network device and powers up an alarm or redundant system when there is no response. Ideal for Hot Standby Servers, Environmental Control, Alert for any network failure.

• IP Address 1 and 2: Enter the IP address(es) of the device(s) to be pinged.

• Frequency 1 and 2: Enter the desired ping frequency in seconds for the device(s)

to be pinged (1-999 seconds).

• Fail Count 1 and 2: Enter the number of times the ping must consecutively fail

(1-999) before the selected action is triggered.

• Mode: Select the logic to be used (AND, OR, or Single). With AND logic, both

AutoPings must exceed their fail count to trigger the action. With OR logic, the action will be triggered if either AutoPing exceeds its fail count. With Single, only AutoPing 1 is used.

SA-20-AR User Manual

______________________________________________________________________________

• Action: Select the action to be triggered.

None

AutoPing not used

Power On – Latch

Upon triggering, AR will power on and remain so until changed via web, telnet, or DxP.

VII. DxP PROTOCOL

Overview

The DxP Protocol is a packet-based protocol designed to be extensible. This protocol is transmitted over TCP on a user-defined port. The factory default DxP port is 9100.

The protocol uses a Hello handshake to establish unique sequence numbers to allow for advanced security when AES encryption is used. With AES enabled, all messages must be encrypted with the AES Passphrase set in the device.

After the Hello, a Command and Response sequence follows. Any number of Command → Response sequences are permitted after Hello.

Hello Handshake

The client sends a Hello message in the form of a text string ‘hello-000’. The DxP enabled device will respond with a packet containing the unsigned 16-bit sequence number. This sequence number is incremented by the client and server with each correct packet sent.

Example:

Client

Server

hello-000

→

← 1234

(seq 1234)

Command (seq 1235)

→ ←

Response

Command (seq 1237)

→ ←

Response

Payloads

o TChangeRelay

typedef struct{ unsigned char relay; unsigned char state; } TChangeRelay;

Where relay is the number of the relay to be affected – 1 (For example, 0 for relay 1 and 1 for relay 2) and state sets the state of the relay (1=Energize; 2=Relax).

o TChangeRelays

typedef struct{ unsigned char relayStates[32]; }TChangeRelays;

Where relayStates is an array of relay states as defined below:

#define NO_CHANGE 0 #define ENERGIZE 1 #define RELAX 2

This payload is supported by devices that support the DxP protocol with 2-32 controllable relays.

o TPulseRelay

typedef struct{ unsigned char relay; //the relay to be pulsed unsigned char state; //the state to pulse uint16 pulseWidth; //the pulse width in seconds }TPulseRelay;

Where relay is the number of the relay to be affected, state is the state to pulse, and pulseWidth is the time to pulse in seconds.

VIII. FIRMWARE UPGRADES

The AR can be upgraded via the network if the upgrade feature has been enabled. To perform a field upgrade, follow the steps below.

Important: Upgrading the firmware with a minor upgrade (For example, 1.01.xx to 1.01.yy) will not alter the user defined settings. Major upgrades may or may not reset the AR to factory defaults. Check the release notes for the upgrade before making any changes.

1. Download the latest firmware version and Device Management Utility (DMU) from the

SurgeX website: http://www.surgex.com.

2. Enable the upgrade feature. Use the CLI set upgrade enable yes command via telnet, or

check the “Upgrade Enable” box on the Device web page.

3. Run the DMU. If the AR you would like to upgrade is not visible in the list box, either:

• Select Device | Discover from the menu to locate the ARs on the local network.

• Select Device | Add from the menu to manually add the AR by IP address.

Once the device is displayed in the list, highlight it.

4. Select Manage | Upgrade Firmware.

Enter User Name admin and the password for the Administrator. Enter the filename of the new firmware or click Browse and navigate to the firmware file

to be used. AR firmware files use the file extension .g2u. If no files of that type are displayed, ensure that the “Files of Type” box is set for SX-iPD or All Files.

Click OK when all details are entered.

5. The upload will begin, and a progress bar will be displayed.

6. When the firmware upload is complete, the AR will automatically reboot and will be

ready for use.

IX. RESET BUTTON

The recessed reset pushbutton located on the side panel performs 3 functions as detailed below:
