Can't access to switch interface, don't know the IP, it's connected | Cisco SG300-28PP

Hey everyone,
First of all my knowledge in this field is very simple, so please bear with me.

I need help figuring out why I can’t access the web configuration page, let me explain.
The switch is connected to a server (Storenator from 45Drives.com), we installed on each PC PCI Express network: Intel® Ethernet Converged Network Adapter X550-T2
The switch is working; it's connecting our server (data storage aka Storenator from 45Drives.com) to the PCs. however, the speed is extremely low, the copying speed is 11MB/ps as it supposed to be 1250MB/ps max (10Gbps). And this is happening with 2 PCs so that tells me it’s not the PC.

To find the bottleneck, I double-checked the drivers are up-to-date, the cables are fine and there is no issue from the server-side, the only missing thing is configuring the switch, I have tried to connect using the default IP but got nothing
The switch (as far as I know) hasn't been configured, just unboxed, connected without any configuration.

I have connected a laptop to the switch and used PuTTY with no success.
Connected a cable to the backport where it reads “Console” but that didn’t work too.

I can access the server, which means there is a connection between the server, the switch, and the client, the only problem is with the connection speed.
Do I have to reset the switch and try again?
What the worst could happen if I hit the reset button?
Please help

I should mention this as it may help somehow:
The Power LED "System" is blinking.
The left (yellow) LED on ports are blinking
Some images attached

My switch is Cisco SG300-28PP 28-port Gigabit PoE+ Managed Switch 
Cables are CAT6
10Gb Adapter Intel® Ethernet Converged Network Adapter X550-T2
PCs are running Windows 10

Hello,

 

out of the box, the default IP address is 192.168.1.254, username and password are cisco/cisco. If those don'twork, try the reset button and use these values again.

 

The speed problem is probably due to speed/duplex settings. Toggle the network cards on the PC between auto/auto and e.g. 1000/full, and see what works.

 

Just in case, attached is the user guide...

Thanks for the reply George,

After a troubleshooting session with the support agent, I believe the NICs are fine.
I think that leaves me only with resetting the switch.

If anyone has any ideas I would really appreciate it

here is the reset of the switch, (if you have switch access still, please take back up for reference - do not restore you may end of same issue again)

Thanks for the replay Balaji, but I don't understand how to take backup when I can't log in to the switch interface?

if you do not have access, there is no other option to reset to factory and start configuring from scratch.

that is the reason i was  mentioned "if you have switch access still, please take back up for reference"

First I'd like to thank everyone replied.

 

Update:

I have removed all the cables, and made a reset to the switch, then connected only one cable to a laptop and changed the IP from dynamic to static and that solved the issue of accessing the switch UI.

 

However, that didn't solved the speed problem, still troubleshooting.
