Hi,

The HWIC cards support a much greater bus bandwidth (400 Mbps) than the WIC cards. Therefore, they are able to support a much higher port density than and greater speeds than the WICs. You can insert WICs in HWIC slots but not vice versa.

It also has a third row of pins, supporting power over ethernet and Cisco inline power. You can also get them in two form factors - single-wide or double-wide.

Hope that helps - pls rate the post if it does.

Ok,

Yep, there are some differences apart from the number of ports.

The HWIC-4T can support up to 8Mbps on each port at the same time (for a total of 32 Mbps) on all supported platforms (it's not supported on the 1800 series routers).

The throughput possible on the WIC-2T depends on the platform it is installed in:

* Supports one port at 8 Mbps when used in NM-1FE1R2W, NM-1FE2W, NM-2FE2W, or NM-2W, or Cisco 2600 chassis WIC slots. All other WIC ports on that network module or Cisco 2600 chassis must not be used.

* Supports two ports at 4 Mbps each when used in NM-1FE1R2W, NM-1FE2W, NM-2FE2W, or NM-2W, or Cisco 2600 chassis WIC slots. All other WIC ports on that network module or Cisco 2600 chassis must not be used.

* Supports 8 Mbps on all ports simultaneously on 2691, 3725, and 3745. No restrictions. Maximum six ports at 8 Mbps each.

Hope that helps - pls rate the post if it does.

Hi Basil,

There is really no better place than the data sheets for the products.

Here are links to the relevant datasheets:

Hope that helps,

Paresh
