We just received a new Cisco Catalyst 2960, and in the box came an item we've never seen before. Interestingly enough, the documentation shows an image of the object, but it is not listed anywhere else in the guide (including the legend, which is numbered incorrectly)!

My buddies and I think it's some type of cable management device. Can anyone identify and elaborate as to its proper use?

Here is an image from the getting started guide (with the object circled):

Very strange. I didn't get those with MY stack of 2960s. – Magellan Mar 28 '12 at 19:11
After you get your answer you should contact Cisco and let them know the diagram is incorrectly labeled. 14, 15 and 16 in the diagram are 13, 14 and 15 in the legend. This new part (probably a power cable securing device like @xeon said) was inserted and the legend never updated. – voretaq7 Mar 28 '12 at 19:12
@Adrian Maybe you should have been nicer to your Cisco sales representative! – voretaq7 Mar 28 '12 at 19:12

Looks like parts to hold the power cable into the switch.

That's it! We took a look at the back of the switch and there are a couple of tangs to hold the metal piece in place. – newmanth Mar 28 '12 at 19:08
Yep. It should hook somewhere behind the PSU a "grabs" the cable. – MDMarra Mar 28 '12 at 19:08
Thanks, I'll accept your answer once the waiting period expires... – newmanth Mar 28 '12 at 19:09
That'd be my guess as well - can you post a photo of the actual parts? – voretaq7 Mar 28 '12 at 19:10
@voretaq7 I suppose, it depends what you do at those workplaces. – JamesBarnett Jan 29 '13 at 2:09

It's part of the power cable assembly. It serves two functions:

  1. Mechanically hold the power cable in so it can not be accidentally pulled
  2. Stress relief on the power plug itself, so the weight of the cable doesn't either loosen the connection or cause a short

I've seen this as standard equipment in all Juniper EX series switches, but the first time I've seen it on a Cisco. Also easier to install than a lot of other supports, since the support body screws on around the power cable.

+1 for the additional info. Thanks! – newmanth Mar 28 '12 at 19:12
