The modules can be inserted with the power still on so I guess you are looking at a hardware failure.

Have you tried reseating the module and rebooting the router?

Problem Hwic-4ESW 2 unit on chassis

Hi Rechard,

Please find the info regd this problem.

Prerequisites for EtherSwitch HWICs

  • Configuration of IP routing. See the Cisco IOS IP Routing: Protocol-Independent Configuration Guide for the Cisco IOS Release you are using.
  • Use of the Cisco IOS T release, beginning with Cisco IOS Release 12.3(8)T4 or later for Cisco HWIC-4ESW and Cisco HWIC-D-9ESW support. (See the Cisco IOS documentation.)

Restrictions for EtherSwitch HWICs

  • No more than two Ethernet Switch HWICs or network modules must be installed in a host router. Multiple Ethernet Switch HWICs or network modules installed in a host router will not act independently of each other. They must be stacked, as they will not work at all otherwise.
  • The ports of a Cisco EtherSwitch HWIC must not be connected to the Fast Ethernet/Gigabit onboard ports of the router.
  • There must not be inline power on the ninth port (port 8) of the HWIC-D-9ESW card.
  • There must not be Auto MDIX support on the ninth port (port 8) of the HWIC-D-9ESW card when either speed or duplex is not set to auto.
  • There must not be support for online insertion/removal (OIR) of the EtherSwitch HWICs.
  • When Ethernet Switches have been installed and configured in a host router, OIR of the CompactFlash memory card in the router must not occur. OIR of the CompactFlash memory card will compromise the configuration of the Ethernet Switches.
  • VTP pruning is not supported.
  • There is a limit of 200 secure MAC addresses per module that can be supported by an EtherSwitch HWIC.
  • Maximum traffic for a secure MAC address is 8 Mb/s.

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.

Note


Without this configuration and connection, duplications will occur in the VLAN databases, and unexpected packet handling may occur.

Please go thu this doc...

I hope your problem will be solved
