Assigning an IP Address to a Switch

1. Select the default VLAN interface

  config t
  interface Vlan1

2. Assign an appropriate IP and enable the interface

  ip address 192.168.X.X 255.255.255.0
  no shutdown
  exit

3. Set the default gateway

  ip default-gateway 192.168.X.X
  exit

NOTE: If ports are using a different VLAN, for instance VLAN5, then you will have to create new VLAN interface and assign the IP to it to make this work.
