To expand on What Luc said, the switches sold and installed by EMC are not managed. Now that's not to say that they are not manageable, however we do not require, nor as a matter of standard delivery practice do we connect them to a customer's network for management or monitoring. We monitor IB based upon the data flowing in and out of our IB cards in the nodes themselves.
That said, you can from a node on the cluster as root, get some detail about the switches. (model number, number of ports and manufacturer, plus GUID).
If you really want the switch serial numbers at this time, my recommendation is to either:
a) look at your EMC Packing list, which should contain the information
b) look at the switches themselves and record the serial numbers for later use. I realize that this is often difficult or impossible if you are not in the same building as the cluster in question, however asking someone at a CoLo or a remote datacenter to document the serials should be very low effort.
I don't know what kind of switches you have, but for my 8-port mellanox QDR switches in the lab the details on where to get the serial number are at the bottom of page 10/ top of page 11 here:
" Occasionally, InfiniBand switches that provide the back-end networking for an Isilon cluster need to be upgraded to increase the number of available ports. The procedure to upgrade switches while cluster is in production is now available in the Isilon Procedure Generator."
The generator has been replaced by the SolVe Desktop. Please check for more information here if needed:
Certainly no disagreement from me. There are a couple of approaches to take here.
1. Run a couple 1Gbe network connections to your IB switches, and assign IPs just so that you can manage or monitor them. (this is not something that EMC does as part of a normal delivery process, but if going forward this is important to you, then ultimately it's your equipment.)
2. Perhaps slightly more secure use a serial console server to connect to the serial ports of your IB switches for remote management, (some people also use these to connect to nodes). Again also not standard procedure, but it does work.
The trouble with both of those options are certainly that they potentially offer more external network exposure to the cluster's back-end, and could have their own security vulerabilities.
So then there is option 3, which probably sounds like boiler-plate, but rest-assured it is helpful.
3. Ask your account team to file an RFE (Request For Enhancement) on your behalf. They sometimes take some time to come to fruition, but these are tracked, and the more frequently product management and engineering hears a common request, the more likely it is to get done.
The answer I provided was for serial access to a node, not to an IB switch, I mis-read the question, sorry for any confusion. The Serial port settings of the IB switches will be dependent on the switch manufacturer, either Mellanox, or Qlogic (Qlogic's IB division is now a division of Intel). If you can tell us what model of switch you're running I'm sure we can dig them up.

Khkris,
To expand on What Luc said, the switches sold and installed by EMC are not managed. Now that's not to say that they are not manageable, however we do not require, nor as a matter of standard delivery practice do we connect them to a customer's network for management or monitoring.

That said, you can from a node on the cluster as root, get some detail about the switches. (model number, number of ports and manufacturer, plus GUID).
isi02-1# cat /var/log/opensm*.topo | grep "Device\[0\]"
Device[0] => 0002c9020046403b 0002c90200464038 (SW, 8) Infiniscale-IV Mellanox Technologies
Device[0] => 0002c902004717db 0002c902004717d8 (SW, 8) Infiniscale-IV Mellanox Technologies

For some basics about IB, if you're interested, Mellanox has a nice primer here:
http://www.mellanox.com/pdf/whitepapers/IB_Intro_WP_190.pdf
If you really want the switch serial numbers at this time, my recommendation is to either:
a) look at your EMC Packing list, which should contain the information
b) look at the switches themselves and record the serial numbers for later use. I realize that this is often difficult or impossible if you are not in the same building as the cluster in question, however asking someone at a CoLo or a remote datacenter to document the serials should be very low effort.

http://www.mellanox.com/related-docs/user_manuals/IS5022_User_Manual.pdf
The opensm*.log files that Luc mentioned show a nicer graphical representation of the IB network, but still the GUID is all that is shown per switch.
Hope this helps, if it does answer your question, please mark it as answered.

If you are looking to pull the SN of IB Switch from the cluster, this is not possible at this time. You may see the SN in /var/log/opensm*.log.
You may find some useful info in the IB Switch Upgrade :

Hi LucSimard,
you referenced an internal EMC page.
The document states the following:
" Occasionally, InfiniBand switches that provide the back-end networking for an Isilon cluster need to be upgraded to increase the number of available ports. The procedure to upgrade switches while cluster is in production is now available in the Isilon Procedure Generator."
The generator has been replaced by the SolVe Desktop. Please check for more information here if needed:

my Colo charges for everything you ask them to do in our cage, getting serial numbers from IB remotely would be very helpful.

Adding to Chris's statement, you can get the serial of the managed Qlogic switches thru CLI and "Chassis View".

Chris,
does console access require credentials ? Baud settings ?
Thanks

If the node is up and running, the login over console will appear identical to an SSH login, and use the same credentials.
Serial settings are:
115,200
Parity-None
Data: 8
Stop: 1
Flow-Control: Hardware
Hope this helps,
~Chris

Chris,
are you saying when i change my cluster credentials, Infiniband credentials get changed as well ?

No,
The answer I provided was for serial access to a node, not to an IB switch, I mis-read the question, sorry for any confusion. The Serial port settings of the IB switches will be dependent on the switch manufacturer, either Mellanox, or Qlogic (Qlogic's IB division is now a division of Intel). If you can tell us what model of switch you're running I'm sure we can dig them up.

Seems "no" on rs323/serial connections, look at page 30 "Note" on Install guide.
NOTE:
If using the RS-232 port, skip to Step 5. Steps 2 through 4 are for those
users accessing the switch via Telnet or SSH.
2. If using Telnet or SSH, access the switch with the following command:
open 192.168.100.9
3. The system prompts for a user name. In order to change the IP address and
default gateway, the user must be logged in as the administrator. At the prompt
enter:
admin
4. The system prompts for a password. At the prompt enter:
adminpass
The system responds with:
Welcome to the CLI. Type 'list' for the list of
commands.
5. To change the switch default IP address enter:
setChassisIpAddr -h ipaddress -m netMask
