Recently, we have had reports regarding “blown” power supply circuitry with Sierra Wireless AirLink Raven X cellular gateways. Sierra Wireless states that this is a known issue, albeit a small one, with the power supply circuit on the Raven X modems manifesting the issue in approximately 1% of all Raven X’s sold early-to-mid 2012.
NOTE: Raven X’s with this issue may fail at any time. Some evidence points to the fact that higher supply voltage (24 Vdc versus 12 Vdc) stresses the faulty circuitry more and makes the issue more likely to manifest.
All modems exhibiting this issue should be returned to Sierra Wireless and will be repaired at no charge under Sierra Wireless’s warranty program. The device will be repaired or the unit will be replaced. The issue has be traced to a faulty component, so once the unit has been repaired, the issue will be mitigated.
This technical issue is very similar to an earlier power circuitry problem with the GX line that Sierra Wireless has since rectified.
To borrow from Edgar Allen Poe, Quoth the raven, “nevermore”
Sierra Wireless has made it official this week that the AirLink Raven X line is going end-of-life (EOL) sooner than their past manufacturing roadmaps indicated. For Raven X the date for the last order placement has been pegged at June 30th 2013. For Raven XT (Verizon Wireless) the date is May 31st. For Raven XE the date is August 31st.
The Sierra Wireless AirLink Raven X, XT, and XT has long been the standard for M2M cell modems in use for Smart Grid applications in the U.S.A.. Sierra Wireless has released the Sierra Wireless AirLink LS300 (1101489, 1101490, 1101491) cell modem as a replacement for this line and many of utility industry clients are currently testing it. Feedback has been good so far, but change is never easy, especially for utility and energy companies where long test-cycles are a part of the best practices.
Is Sierra Wireless going to be firm with their scheduled sunset of the ultra-profitable Raven X line? My inclination is no, however, prudence dictates that the alternative LS300, GX400, and GX440 be tested immediately in order to move them through the standards department and into production.
