Lighting Small Scale Deployment
When a lighting solution needs to deploy in a small store/site where 20 or fewer number of light fixtures are required to be installed, a Cisco Catalyst 3850 standalone switch is sufficient, along with SCM, for the lighting network for provisioning light fixtures. In this small scale deployment, a Syslog server can also be connected to the same Cisco Catalyst 3850 switch to manage this small lighting network.
This chapter, which covers the implementation of networking Layer 2, Layer 3, and security features required for a small scale network powered lighting deployment as specified in the Design Guide, includes the following major topics:
Network Topology
In this deployment, one standalone Cisco Catalyst 3850 UPOE is sufficient to implement lighting in a small scale (for example, up to 20 lights in a small retail store) as shown in Figure 6-1.

Wiring Closet Access Switch (Cisco Catalyst 3850)
When migrating a lighting initial setup with a Cisco Catalyst 3850 standalone switch for a small scale deployment, SCM is connected directly to the Cisco Catalyst 3850 switch for provisioning light fixtures. Networking Layer 2, Layer 3, and UPOE and security features are also configured on the Cisco Catalyst 3850 switch.
Configuring DHCP Server for Light Fixture IP Addressing
When migrating the initial lighting setup to a small scale deployment, the DHCP server IP addressing pool for light fixtures and wall dimmers is configured on the Cisco Catalyst 3850 switch itself to assign IP addresses to Cree endpoints.
Table 6-1
shows an example DHCP pool range for Cree light fixtures.

Perform the following steps to configure DHCP server pool on Cisco Catalyst 3850/Cisco Catalyst 4506-E switches.
Step 1 Follow Configuring Network Layer 2 and Layer 3 from Steps 1 to 4 in the Wiring Closet Access Switch configuration section in Chapter 4.
Step 2 Configure DHCP server on the Cisco Catalyst 3850 switch. For example:
network 10.30.0.0 255.255.252.0 ip dhcp excluded-address 10.30.0.1 10.30.0.50
