请问,3845路由器是否支持同时运行两块NM-16ESW板卡

如题,我现在有台3845路由器本来接了一块NM-16ESW板卡,由于业务多现在16个以太网口基本上插满了,所以又插了一块NM-16ESW板卡,板卡插上后,查看板卡状态正常,然后接了一个业务测试,结果发现接在新板上后端口对应的绿灯亮了,但是业务不通,然后把业务再接回旧板子上,业务就通了,然后我直接接笔记本做测试,结果发现现象一样,接在新板子上网关都ping不通,接到旧板子上就通了,网关是在这台路由器上vlan16,换了块NM-16ESW板卡现象一样,我怀疑是3845不支持两块NM-16ESW板卡同时运行,但是也不确定,所以请教高手帮忙解答一下了!谢谢! 相关配置如下:
interface Vlan6
ip address 192.168.125.38 255.255.255.248
interface FastEthernet1/0 (旧NM-16ESW板卡)
switchport access vlan 16
interface FastEthernet2/0 (新NM-16ESW板卡)
switchport access vlan 16

You have used the two ESW module on one chassis together, you need understand below info.
NAME: "9 Port FE Switch on Slot 0 SubSlot 1", DESCR: "9 Port FE Switch"
PID: HWIC-D-9ESW , VID: V01 , SN: FOC12072R2X
NAME: "16 Port 10BaseT/100BaseTX EtherSwitch on Slot 1", DESCR: "16 Port 10BaseT/100BaseTX EtherSwitch"
PID: NM-16ESW , VID: V01 , SN: FOC13341F3Q
1/How many Cisco EtherSwitch modules can be installed on a Cisco 3800 Series system?
A. Up to two modules. Configurations with two modules require that the Cisco EtherSwitch modules are stacked. A Cisco EtherSwitch HWIC can be
stacked with a Cisco EtherSwitch network module by connecting the Gigabit Ethernet port of the network module to a Fast Ethernet port of a
HWIC card. Similarly, two Cisco EtherSwitch HWICs or network modules can be stacked by connecting to each other.
2/Prerequisites for Installing Two Ethernet Switch Network Modules in a Single Chassis
A maximum of two Ethernet switch network modules can be installed in a single chassis. If two Ethernet switch network modules of any type are
installed in the same chassis, the following configuration requirements must be met:
• Both Ethernet switch network modules must have an optional Gigabit Ethernet expansion board installed.
• An Ethernet crossover cable must be connected to the two Ethernet switch network modules using the optional Gigabit Ethernet expansion board ports.
• Intrachassis stacking for the optional Gigabit Ethernet expansion board ports must be configured. For information about intrachassis stacking configuration, see the
16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series feature module.

3/Configuring Intrachassis Stacking
Router(config)# interface Gigabit slot/port
Router(config-if)# [no] switchport
stacking-link interface Gigabit slot/port

4/Intrachassis Stacking Example
The following example shows how to stack GE port 2/0 to GE port 3/0 to form an extended VLAN within one chassis:
Router #config terminal
Router(config)# interface Gigabit 2/0
Router(config-if)# switchport stacking-link interface Gigabit3/0
show interface
GigabitEthernet2/0 is up, line protocol is down
Internal Stacking Link Active : Gi2/0 is stacked with Gi3/0<<<<
