Issue
Com'X 210/510 GPRS Settings

Product Line
Com'X 210
Com'X 510

Environment
Installation/Setup

Cause
GPRS access settings depend on the GPRS modem that is connected.

Resolution
There are 2 reference numbers for the GPRS modem:
  • EBXA-GPRS-SIM
  • EBXA-GPRS
NOTE: The good operation of GPRS and Wi-Fi is not guaranteed with other GPRS modems or Wi-Fi USB keys.

The SIM card is embedded in the GPRS modem. You can only use the EBXA GPRS SIM to publish data if you are exporting data to Remote Service Platform. The settings of this GPRS access are set by the Com'X.
The reference EBXA-GRPS-SIM must be selected for the GPRS modem.
This graphic shows the interface for accessing the GPRS modem with an EBXA GPRS SIM card:


NOTE:
For the Com'X that comes with the SIM card included: The SIM card that comes with the Com'X 510 is Vodafone, but will connect to the T-Mobile network in the United States once the card is activated. 

For the Com'X without the SIM card included:  Provided that the cellular provider will allow the equipment on their network, and the user configures the proper APN and SIM card settings, there are no constraints for putting the ComX on another GPRS network. 
 

Symmetra PX 250/500 Battery to Power Module Ratio

Issue:
Symmetra PX 250/500 Battery to Power Module Ratio

Product line:
Symmetra PX 250/500

Environment:
All Product models, all serial numbers

Cause:
Required battery to power module ratio for a Symmetra PX 250/500

Resolution:

Ratio between numbers of battery shelves and power modules (PM)

Maximum recommended discharge level on the batteries used for Symmetra PX 250/500 is 3CA, where CA means the current (Amps) by which the battery is charged or discharged divided by its Amp-hour (Ah) rating.  The 250kW runtime ratio is 10 PMs to 16 battery shelves resulting in a ratio of 1.6 battery shelf per 1 PM. Need to always round up the number of shelves

Results if ratio is not maintained

In some situations, the Power Modules will attempt to draw power from the batteries and if the ratio is not observed, you will potentially clear fuses in the battery modules and (less likely, but it happened before) burn traces on the battery backplane boards due to the DC inrush current.

Resolution

If the total measured leakage current exceeds 3.5mA we recommend to attach a ground wire from the Rack ATS supplementary ground (M4 thread) to a reliable ground connection before energizing the Rack ATS.
The value of 3.5mA is in conformance with IEC/EN 60950 clause 5. The leakage current value of the ATS without loads installed is below the limits required in Table 5A of the standard. The supplementary chassis ground terminal connection is recommended for installations to the meet their requirements if the known or measured leakage current exceeds 3.5mA.
 

Explanation of circuit breakers in 30 amp rPDU's

Product Line
  • Rack Power Distribution
    • AP7XXX, AP7XXXB, AP8XXX series

Environment
  • All serial numbers

Resolution
Circuit breakers are in place to protect the branch circuit and its conductors. With respect to a 30A breaker, all components employed in the circuit (downstream from the circuit breaker) shall be rated for 30A use. In a scenario where a 30A circuit breaker is providing power to a 20A rated outlet, the outlet, load plug, load cord and load are rated for 20A use, thus sized for this rating. In this scenario there is inadequate protection for the outlet and all connected equipment, and potentially (and most harmfully) the conductor that is supplying the outlets themselves.

In North America, Canada, and Europe, PDU's are evaluated under UL/CSA/EN/IEC 60950-1. This standard requires circuit breaker protection when the rating of an output is less than the rating of the input. A PDU with a 30A input plug and 20A receptacles must have circuit breakers. Section 2.7 of the 60950 standard states: "Protective devices necessary to comply with the requirements of 5.3* must be included as part of the equipment" 

*5.3 is the evaluation of abnormal operating and fault conditions.


In North America, the requirement is based on NFPA 70, the National Electrical Code. In general, in the United States, you can have any outlet rated less than 20A protected by a 20A breaker. However, these outlets must have protection rated no less than the outlet rating and no more than 20A. A 30A outlet must be protected by a 30A breaker and may not have anything larger or smaller.

Europe has very similar rules to North America. The main difference is the rating of receptacles and breakers. In Europe, you typically have 10A or 16A outlets protected by a 16A breaker, but the breaker rating can be no more than 16A.

Canada places additional restrictions. In Canada, a 15A outlet must be protected by a 15A breaker. The only exception is the "T-Slot" 20A outlet that accepts either 15A or 20A plugs. This outlet may be protected at 20A.


If a PDU has a 30A plug and 30A receptacles, it will not require and internal circuit breaker. The 30A plug forces it to be plugged into a 30A branch circuit, which will have its own 30A breaker. The PDU can then rely on the branch circuit's breaker rather than an internal breaker.

If a PDU has a 30A plug and 20A receptacles, it must have internal 20A branch rated breakers for the receptacles. The 30A protection of the branch circuit is too high to be safe for the 20A outlets.

UPDATED MARCH-2016: Unable to access my APC Network Management Card (NMC) enabled device via HTTPS (SSL/TLS)


Issue

The user is unable to access their APC Network Management Card (NMC) products via HTTPS (SSL/TLS) secured web access.

There are two parts to this issue, both of which occur when the user has their Network Management Card product configured for SSL (HTTPS).
  1.  Companies such as Microsoft, Mozilla, and Google are disabling SSLv3.0 in their browser products due to numerous security vulnerabilities that exist. One such vulnerability is POODLE (https://www.openssl.org/~bodo/ssl-poodle.pdf).  TLSv1.0, at a minimum, is the advised protocol.
 
  1. TLS does not work on the current NMC products.  Therefore, the NMC will fall back to SSLv3.0 and as such, be vulnerable to POODLE.

Examples:
 
An example of this problem, shown via Firefox, is below. A NetBotz Rack Monitor 200 (SKU# NBRK0201) is configured for HTTPS. The user has Firefox v34.0 installed. The user opens their web browser and types the IP address into address bar.  The user is presented with the following error message:
 

Another example of this problem, via Internet Explorer, is below. A NetBotz Rack Monitor 200 (SKU# NBRK0201) is configured for HTTPS.  The user has Internet Explorer v11.0 installed. The user opens their web browser and types the IP address into address bar.  The user is presented with the following error message:
 

Another example of this problem, via Chrome, is below. An AP9631 Network Management Card is configured for HTTPS. The user has Chrome v39 installed. The user opens their web browser and types the IP address into the address bar. The user is presented with the following error message:
 


Browser error messages may include: ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION, ssl_error_no_cypher_overlap


Note: If you've received mozilla_pkix_error_inadequate_key_size, sec_error_invalid_key, or anything referring to invalid key size/length, please consider reviewing knowledge base article ID FA162031 as this may be due to a separate issue entirely or an additional issue.

Environment

Any customer who uses any one of the products mentioned previously and:
  • Configures their product for SSL (HTTPS).
  • Uses a web browser version that does not allow for web access via SSLv3.0.
Note: HTTP users are not affected. Meaning, if you have not enabled HTTPS (SSL), web browsing will work normally.


Cause

Companies such as Microsoft, Mozilla, and Google are disabling SSLv3.0 in their browser products due to numerous security vulnerabilities that exist. One such example is POODLE (https://www.openssl.org/~bodo/ssl-poodle.pdf). TLSv1.0, at a minimum, is the advised protocol.

Current NMC products have an inability to properly utilize TLS extensions recently released in several modern browsers. With this inability, the NMC device is unable to connect to the browser via TLS. While future versions of the NMC1 devices will not update the underlying cryptology engine, NMC2 devices will be updated to work with current TLS specification and and operate properly with modern browsers.


Resolution

A customer can avoid this problem either by utilizing other access methods on the Network Management Card or they can modify their web browser to allow SSLv3.0 usage (at their own discretion). Other access methods for the Network Management Card are as follows:
  • Local console
  • Web (HTTP)
  • Telnet/SSH
  • SNMPv1/v3

Modifying a web browser to allow SSLv3.0 usage should be addressed by the user’s network security team or facility manager. Schneider Electric will not provide users with instructions on modifying web browser settings. Some users may be prohibited from enabling SSLv3.0 through their web browser.

Any of the following NMC1 products do not currently have any firm future firmware update plans to address this or any future vulnerabilities:
  • AP9921X Battery Management System
  • AP7750, AP7722, AP7701 Rack Automatic Transfer Switches
  • AP9340, AP9320 Environmental Monitoring Units

Note: Certain browsers may also require setting changes to allow TLS 1.0 or TLS 1.0 fallback too, such as Firefox v37+. Schneider Electric will not provide step by step instructions for modfying web browser settings for liability reasons but if you're comfortable modifying settings at your own risk, security.tls.version.fallback-limit within Firefox will likely need to be changed from a default value of 3 (forcing TLS 1.2) to a value of 1 to allow fallback to TLS 1.0. This setting also sometimes resets itself between Firefox browser upgrades. Newer Chrome versions may require --ssl-version-fallback-min=tls1 to be appended to the program shortcut.


A fix to address this problem in the Network Management Card 2 (NMC2) and NMC2 enabled devices has been implemented. The release date will be determined on a product by product basis. See below for available updates for NMC2 firmware applications. These updates provide TLS 1.0, TLS 1.1 and TLS 1.2 functionality.

 Can this problem be confused with other error messages generated by the Network Management Card?

Yes, a user may receive different error messages relating to SSL/TLS when configuring or accessing their Network Management Card device.  It is imperative that Schneider Electric and the user identify the exact error message that the user is receiving and confirm that it relates to this specific issue, related to SSLv3.0.

For example, similar symptoms could be experienced by the issue in knowledge base article ID FA162031 - Network Management Card 1 (NMC1) Information Bulletin: Effects of Microsoft Internet Explorer and other web browsers blocking key lengths less than 1024 bits​(blocking key lengths less than 1024 bits)
