By issuing the write erase command and the reload command, you restore the switch settings to their factory defaults. This sequence also restores the redundancy mode setting for the power supplies back to the redundant mode (default).
Depending on the type of power supply, the input voltage, and the number of modules (line cards) in the chassis, the redundancy mode may prevent the line cards from being powered on after a system reboot (see the "Power Supply Configuration Modes" section on page 11-10). If you use this sequence, the commands that apply to the powered down line cards will not be enforced on the switch (and will not be part of its running configuration).
If using the write erase and reload command sequence before rolling back to a saved configuration, follow these steps:
Step 1 Manually change (if originally configured) the redundant mode configuration to combined mode. Step 2 Wait until all modules are back online. The module status displays ok in response to the show module command. Step 3 Roll back to the saved configuration (see the "Rolling Back to a Previous Configuration" section on page 9-7).

LZ试一下手动将Power Supply的模式改到combined mode看看。另外write erase boot后交换机就回到出厂设置了,admin password也需要重设。
