     108== VN6 GPY111 limited ESD protection
     109
     110Issue:
     111 * The GPY111 PHY used on a variety of boards lacks internal ESD protection to the level of modern standards which could result in network functionality being permanently limited due to ESD cable hot-plug events.
     112
     113Workaround:
     114 * For outdoor applications and boards that could be exposed to electrical events, we would recommend you use an external RJ45 surge protector. The following product also additionally helps to protect against lightning events up to IEC 61000-4-5 (Lightning) 40A (8/20us):
     115  - [http://datasheet.watchfuleyesolutions.com/US121101.html Watchful Eye WTH-SG/RJ45-S, US121101X] (Also available on Amazon)
     116
     117Resolution:
     118 * additional ESD protection has been added between the GPY111 PHY and magnetics to the RJ45. Note that for GW71xx/GW72xx/GW73xx the GPY111 PHY is on the SoM and the external ESD protection is on the baseboard.

     120Affected Products:
     121 - GW710x-A/B/C baseboard with GW700x-E+ SoM
     122 - GW720x-A/B/C/D baseboard with GW700x-E+ SoM
     123 - GW730x-A/B/C baseboard with GW700x-E+ SoM
     124 - GW740x-A
     125
     126Resolved on:
     127 - GW710x-D (PCB 02210196-03)
     128 - GW720x-E (PCB 02210197-04)
     129 - GW730x-D (PCB 02210198-03)
     130 - GW740x-B (PCB 02210199-01)
     131
     132To determine if your board is affected use the 'gsc' command in U-Boot to see the model of the GW700x SoM and the baseboard:
     133{{{#!bash
     134u-boot=> gsc
