We are unable to login at Cisco 6509 switch, due to username and password not working. We have tried to recover the password as per Cisco document, but that is also not working. This switch is our Primary Switch in our network.

Not sure of checkpoint firewall config....I have run wireshark when trying to telnet and I get no syn-ack back from remote switch.

I have set up a newly switch, cisco 3570C. Its in v15 and the only configuration i did is:
-set up interface ip add. 10.132.16.111
-set up telnet
I am able to telnet within LAN environment. I cant ping or telnet the switch in a WAN enviornment. Is there any setting i should confgure on the switch?
I have a Cisco 2960-S Switch, It is connected to a jack in the building to check the settings, Interface VLAN 1 has an ip, there is a default gateway, Any host connected to switch can access the network resources. But the problem is that I have to use Serial Cable to configure it. I cant ping or telnet into it from any other device. PC's are on different subnets/VLANS.
Basically this switch is connected to a port in a different switch, Do i have to make a trunk?
We have recently purchased SG 300-52Port Cisco Switch to support our Network but they constantly having some bizarre issues or I assume bugs, i.e. we cannot Telnet nor SSH to the switch now, whereas we were able to SSH before, we have set them up for Remote Log Services to get some syslogs and reports but no report have been generated nor logs,
I have done some testing through Wireshark and there are absolutely no reports / logs.We have some real issues with this switch and it’s hard to believe that this is a Cisco Product,
