Hello,
Yes, once you trunk, you can use VLAN 301 and 310 in the second switch. You
need to enable those vlans on the switch by assigning ports to those VLANs.
The trunk will not affect rest of the operations.
Hope this helps.

Hello,
If you are having a flat VLAN structure i.e. only VLAN 1 in the entire network (on both switches), then you can just connect those two ports normally and the switch will take care of the rest. If you have multiple vlans, then you need to configure trunk:
Interface gi 0/28
Switchport trunk encapsulation dot1q
Switchport mode trunk
Exit
This will ensure that both switches communicate through all VLANs.
Hope this helps.

Hi
Let me just give some more on my network so it would not effect or impact
switch1 - ports 1 and 2 are uplink ports for data(301) and voice(310) vlans respectively coming from HP 3550 router
ports 3-23 are access ports
port 24 for switch management in default VLAN1
now te scenario is bring a new switch2 all ports will be access ports
as per your advise
attach the gig0/28 ports with fibre and config the port 28 with
Interface gi 0/28
Switchport trunk encapsulation dot1q
Switchport mode trunk
Exit
now the vlans 301 and 310 will be available and can be used in switch2 as well ?
that trunk would not have any impact?
thanks once again
