How to Test an ATX Power Supply

Although there are portable power supply testers on the market that are inexpensive, it often becomes necessary to test whether a power supply is good or bad with only a multi-meter handy. The following steps detail how to perform this.

<br>

WARNING: When working with electricity always follow proper safety procedures. Remove jewelry from your hands. Do not attempt to open enclosures labeled “Non-Serviceable” or with warnings of electric shock. Do not touch capacitors which may still be holding an electric charge.

<br>

  1. Power down the system and remove the power cable(s) from the device.
  2. Open the server case and unplug the power connectors inside.
    • Follow the large bundle of wires from the power supply to the motherboard. You will find a large, plastic connector. This is typically white but may also be black.
    • Press the release down on one side of the connector and pull up to remove it.
    • A smaller bundle will connect to a 4 or 8-pin connector elsewhere on the motherboard. Disconnect these as well.
    • It is not necessary to remove the entire power supply from the chassis; just pull the connectors to a place you can easily access them.
  3. Examine the pinout diagrams. While some machines may have a 20-pin connector, others will have a 24-pin connector. With the pins facing you and the release clip towards the right the top-left pin will be pin number 1 and follow down the left side before beginning again at the top of the next column.
  4. You will need a short piece of wire to use as a jumper for the next step. If you have a 20-pin connector, insert the ends of the wire into pins 13 and 14 to short out this connection. If you have a 24-pin connector, insert the wire into pins 15 and 16
    • 20-pin -->  13 to 14
    • 24-pin -->  15 to 16
  5. Plug in the power supply. If it has no power switch you should hear the fan come on. If it does have a power switch, turn the unit on.
  6. If you have an Auto-Ranging multi-meter you can just set it to DC Voltage. If you have a traditional multi-meter, set the dial to the 10-Volt setting.
  7. Place the black (-) probe from your multi-meter on any of the pins labeled Ground (GND). Place the red (+) probe on the first pin and work your way around to each pin.
    • Make a note of the voltage reach from each pin. Click here for a printable worksheet to record these readings.
  8. Compare the values from your meter readings to the value that should be supplied.

Note:  These will almost never be exactly 3.3, 5.0 or 12.0 volts. Your actual meter readings should fall between the minimum and maximum voltage tolerances.

<br>

If your readings are above or below the allowable tolerances, noted on the worksheet, for that pin the power supply should be replaced.

E-Series 1-channel and 4-channel Official Firmware Version

INTERNAL NOTE: E-Series Encoders are EOM and non-NDAA compliant devices.

<br>

Some E-series encoders are having trouble with network communication. Attempts to connect with ExacqVision server, E-series utility or even find using ARP commands fail.

<br>

It was found that some encoders were shipped with firmware 1.2.0.150420 pre-installed. This firmware is for testing only.

<br>

The official firmware release for the 1-channel and 4-channel Exacq E-Series encoders is 1.2.0.140801.

1.  Start LXTerminal.

2.  Change to admin user.

      su admin 

3.  Change to the admin home directory.

      cd 

4.  Download and execute the m-series script from translations server.

curl -fsSL https://translate.exacq.com/m-series.sh | sh 

5.  Progress messages will scroll as the script executes. The last will be about installing the m-series lang.

Enable Translations

The process is the same for any language, but this example shows application of Japanese.

1.  Open System Settings dialog. Enter the admin password when prompted.

2.  On the Language and Keyboard tab, press Configure Locale.

3.  Check ja_JP.UTF-8 from the list and press Forward.

4.  Select ja_JP.UTF-8 from the drop-down and press Forward.

Redirecting HTTP to HTTPS with Web Sevice 9.0 – 19.06

NOTE: This document does not apply to Web Service versions 19.09 and higher.

Best Practice is to use the latest version of Web Service available.

The way the web service handles HTTP requests when HTTPS is configured can be controlled with the webserver.tls.httpPolicy key:

Open the following file in a text editor:

Windows: C:\ProgramData\Webservice\conf\wfe.json
Linux: /etc/webservice/wfe.json

Add the “httpPolicy” line as shown below.

{<br>
    "webserver": {<br>
        "listen": 80,<br>
        "tls": {<br>
            "listen": 443,<br>
            "httpPolicy": "redirect",<br>
            [...]<br>
        }<br>
    }<br>
}

The key can be one of the following values:

  • “redirect” will cause HTTP traffic to be redirected to HTTPS
  • “disable” will reject any requests not sent over HTTPS

NOTE: This key will only take effect if after a Web Service restart, and if SSL is configured.

Drives displaying “Red” on Storage Drive and Hardware tab

Description

Drives showing offline or write error on Storage => Drive tab and Hardware tab.

<br>

Workaround

Open Windows device manager (Windows start menu and type “device manager”)
Expand IDE ATA/ATAPI controllers
Check to see if there are duplicate ATA Channel entries (ATA Channel 0, ATA Channel 1, etc)
Disable the “Standard Dual Channel PCI IDE Controller” and reboot to remove the duplicates.
If the “Standard Dual Channel PCI IDE Controller” does not exist, disable the second entry for each duplicate ATA Channel by right clicking and choose disable.
Reboot the server

Exacq Storage Issues

Drives failing WD Self Test

Issue

Drive shows failed on the Hardware tab in the exacqVision Storage area.
Certain combinations of exacqVision and other read/write data could cause the Western Digital Drive Short Test (WD DST) to intermittently get stuck in a loop and write excessively to a specific physical drive location dedicated for testing, which causes false failure alerts.

Affected Version

Exacq Server 7.8 – 8.0


See KB: 22936 https://exacq.com/kb/?crc=22936 for more detail

<br>

Drive not found HBA issue

Description

The HBA (Host Bus Adapter) can get damaged by the HBA clamp. Specifically the SATA 3 port capacitor can get damaged.

NOTE: The damage to the HBA does not affect all units. This has been seen in a very limited number. The clamp is there for shipping purposes only can may be removed. The card can become damaged only during shipping.

Platform

A-Series systems with more than 4 drives (non raid)

NOTE: A-Series IP only systems do not use a hold down bracket for the HBA after 11/01/2016.
NOTE: A-Series Hybrid systems use a modified hold down bracket for the HBA after 11/01/2016.

Drives showing offline in linux

Some users are experiencing multiple drives in an ‘Offline’ status with Linux systems containing host bus adapters. This may also present drives not on the HBA as ‘Offline’ or with ‘Write Errors’.

WD Firmware upgrade for 2TB RR02 drives

Exacq has been made aware of a firmware issue affecting 2TB Western Digital drives. This issue manifests itself on our exacqVision servers as a drive in the RAID Array going to ‘Unconfigured Bad’. While this is a recoverable error, due to the nature of the firmware issue with Western Digital, it will occur again. The scope of when these drives were used is fairly narrow within Exacq.
