Meetinghouse firewalls have a limited number of local area network (LAN) ports that devices can be connected to. A network switch can be used to increase the number of available network ports. In most cases, facility management groups are responsible for purchasing and installing network switches.
Prior to the rollout of the Meraki managed network switches, many meetinghouses were equipped with unmanaged switches like the Cisco SG110 pictured above. These unmanaged switches and others can still be used in conjunction with the new Merakis as long as no unmanaged switch is directly connected to the firewall. Using both the managed and unmanaged switches together can provide more flexibility for the wired network and more room for any additional devices needed in later years.
