So I'm brand new to Cisco awesome equipment though. I bought a switch and when I first booted it up it was stuck in a boot-loop. So I researched and read and through trial and error I got it unstuck and the correct image in place. So I am configuring the switch have not done a tftp server yet and follow a wrong procedure and assign the wrong ip address to the switch I was supposed to be doing a loop-back. So I figured I would just start over good practice right. I'm trying to self teach myself Cisco here that should tell you I'm not the brightest crayon in the box. So I do a clear config all and it works great so great that even though I had supposedly done a running config save I now have no boot image no slot0 image and no boot system flash bootflash image. I did however make me a tftp server with tftp64 but cant for the life of me get the command right for Rommon to drop me an image. Hell at one point I could see on a reset it said boot booted from 0x010 cat4500-entservicesk9-mz.150-2.SG10.bin it was right there just not in the right position I have been driving myself crazy here could someone please throw me in the right direction?

The syntax is incorrect. It should be: dir flash:
NOTE: Please observe there is a ":" at the end of "flash:".
If "dir flash:" doesn't work, then try "dir bootflash:".

Not sure what was different because I swear I ran that exact command a hundred times but there it is and its back up. Feel like a mental midget at the moment but hey thank you very much.

And I take it my 10 G ports aren't configured correctly or just have the wrong hardware?

>... wrong hardware
If you are talking about transceiver check this link for compatibility info's : https://tmgmatrix.cisco.com/?npid=528
If you are using 3rd party transceivers you may want to configure :
service unsupported-transceiver
no errdisable detect cause gbic-invalid

post the output of "sho inventory"
it seems like this is just a 4948, not a 4948-10g. The reason I say that is that the 4948 has port 1-44 as the RJ ports, and 45-48 are either the RJ of SFP. A 4948-10g has 48 RJ ports and two 10gig (X2 transceivers if I remember correctly) slots.

IF in ROMMON (look at the prompt), do the following
delete bootflash:at4500-ios-promupgrade-122_31r_SGA4 boot bootflash:cat4500-entservicesk9-mz.150-2.SG10.bin
Who's actually playing with the switch? I can see the config-register changing from 0x2102 to 0x2142.
