| 594 | == HW35 GPY111 limited ESD protection |
| 595 | |
| 596 | Issue: |
| 597 | * 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. |
| 598 | |
| 599 | Workaround: |
| 600 | * 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): |
