提问: 在WS-C4506-E机箱内插入2块不同PID的电源, 会怎样? 有什么规律?

我们通过在实验室搭建测试环境,来看一下有什么规律.

实验室测试环境:
-WS-C4506-E
-WS-X45-SUP6-E
-PWR-C45-4200ACV
-PWR-C45-2800AC

测试步骤:
1/将4200瓦电源放入电源槽位1(PS1), 再将2800瓦电源放入电源槽位2(PS2),收集sh log和sh env
2/移除4200瓦电源, 再插入4200瓦电源, 收集sh log和sh env
3/将2个电源位置对调,重复以上操作

我们可以通过官网提供的小工具'Error Message Decoder'来解析以上日志.

Error Message Explanation
++++++++++++++++++++++++++++++++++
%C4K_CHASSIS-3-MIXINPOWERDETECTED: Power supplies in the chassis are of different types (AC/DC) or wattage
//机箱内不同类型的电源被检测到
Explanation: The software detected different kinds of power supplies in the chassis. In a Catalyst 4006 chassis, the power values default to the wattage of the weakest power supply. If you mix power supplies in a Catalyst 4500 series chassis, the switch will use the power supply in power supply bay 1 (PS1) and ignore the power supply in power supply bay 2 (PS2). We do not recommend mixing power supplies of different wattages.
//解释: 软件检测到机箱内有不同的电源类型. 在 Catalyst 4500系列交换机的机箱中,如果混合使用不同型号的电源, 交换机将使用槽位1的电源(PS1), 忽略槽位2的电源. 我们不推荐混合使用不同瓦数的电源.


Recommended Action: Verify that both power supplies are the same kind and wattage. Replace a power supply if necessary.
//推荐行为: 检查并确保两个电源槽位使用相同型号电源. 如果有必要,替换成相同型号电源.
++++++++++++++++++++++++++++++++++
总结:
-在Catalyst 4500系列交换机的机箱中, 推荐使用相同型号电源
-如果混合使用不同型号的电源,处于电源槽位2槽的电源将会处于err-disable的状态,与电源瓦数大小无关(不是因为瓦数大或者小,而被err-disable).

瓦数小的, 第2个放入的...
实验才是王道
