Cisco Catalyst 2948G-TX-GE Configuration and Maintenance help

I have a customer that has multiple Cisco Catalyst 2948G-GE-TX Switch's These platforms have been EOL since 2008 and go completely EOL/EOS in 9 months.

I need help finding basic configuration and troubleshooting documentation on this platform. The network is specifically seeing random performance issues between the various CAT OS running 2948G's

Here is the SH Ver from one of the Switches:
