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.
