HWIC-4ESW in 1921

Does Cisco 1921-SEC/K9 support HWIC-4ESW ? I require 4 x 10/100 Ethernet ports

If yes how many ? are there any drawbacks if i use this module instead of a switch?

Regards

Aakash.

HWIC-4ESW in 1921

Cisco 1921 does not support this module, only 1941 supports it.

see table-7 in this link

Re: HWIC-4ESW in 1921

Hi Reza,

I have gone through a cisco datasheet which shows that CISCO1921 supports 2 numbers of HWIC-4ESW !!

Check the link below and in the table 2 look for HWIC-4ESW ! I

I am not sure though! Some datasheet shows that 1921 supports hwic-4esw while some does not! i need to revert back to my client, can any body suggest ???

Hello!

   No it doesn't; this HWIC physically can NOT be inserted in the router so, nothing to do. I didn't used a hammer in my test but I can figure that I shouldn't try!

Page 5 of the document at

http://www.cisco.com/en/US/prod/collateral/routers/ps10538/aag_c07_563807.pdf will confirm that the HWIC-4ESW is supported on the 1921.

Here's one in the 1921 in my office:

Re: HWIC-4ESW in 1921

Well well well,

I could this be possible since we have the same revisions of router and Hwic? This was an easy one and I'm feeling a little shy 'bout it: the middle plastic bracket between the two slots was broke and stops the card at the very end of insertion, at the same place it will habitually stops when a card is not made for a dedicated router. First time in 15 years and it's happend now. Heh, Murphy's law!

I confirm than kmccourt is right and it works correctly:
