Identify the fans used in a Cisco Catalyst 9400 Series Switch

[scott-f-moynihan]

Hello.  This is my first time using the Cisco community, so hopefully I don't screw it up. 

I'm trying to identify the specific fans used in a C9410R Cisco Catalyst Switch.  The vertical fan tray on the side pulls cooling flow through the lower part of the chassis, past the 10 slots for the various cards/blades.  The only product name I can find in the datasheet is "C9410-FAN", which seems to be for the entire tray of 16 small muffin fans.

I'm doing a thermal analysis of a cabinet that houses one of these switches, so I need to understand how much flow the fans can move.  If I had a vendor part number (i.e., from Ametek, Rotron, or similar company) I could track down a datasheet that probably has a performance curve (i.e., of flow vs. pressure).  Unfortunately I have nothing to go on, and don't have the serial number to open a TAC case.

Can anyone help me identify a part number for the individual fan, or suggest the best way of getting that information through Cisco's main website?  Thank you, in advance, for your help.

Hello marce1000.  I appreciate your reply, but that only seems to link me to a site that (a) has information/images I already have, and (b) lets me order one.  I'm doing a thermal analysis of a cabinet that houses one of these switches, so (b) isn't my function.  I need to get some idea of how much airflow the 16 muffin fans will move, so I need a performance curve for a single fan.  That model number is still TBD.  It sounds like I need to identify the serial number of our C9410R switch, and then Cisco may be willing/able to help.  Thanks again, though.

Use the serial number of the chassis.

If not, talk to the Cisco Account Manager so they can reach out to the BU for the information.

Hello Leo.  Thank you for your reply, too...but I didn't have the serial number when I first contacted Cisco...and still don't.  It sounds like I need to contact one of the MEs or EEs in my company to get the number, and then go back to Cisco and ask again for help.

Hello Scott,
This may be too late, but in case you are still looking for this information, it is available in the Hardware Installation Guide:
Fan Tray Assembly
For the C9410R Cisco Catalyst Switch, the applicable fan model  number is C9404-FAN; Add "=" to the model number for spares.
This model has eight individual fans (two rows of four each). It supports a minimum airflow of 640 cubic feet per minute (CFM) at 100 percent fan throttle.
The individual fans are not field replaceable, you must replace the fan tray.

That's good information...thank you, deerao.  It's not quite the fan performance curve I was looking for (i.e., flows vs. pressure), but getting a reasonable estimate of the total flow moved by/through the tray is probably good enough for what I'm doing.
