1. Board hardware reason
2. The version reasons
The 2GE card of Number 2 and 4 slot can not display is because the old version does not support 2GE card. After the upgrade it can solve this problem. Because the Version is relatively old, upgrade to V200R006C02B066 version through the transition version upgrade: upgrade to the first version of the EU300 & 500 & 1000 & SP1800-VRP3.30-0359 (08), and then upgrade to V200R006C02B066 version.
