# Switch tab (NSR, NSR Lite, GSR, and BSR)

These functions are only available on Nodegrid NSR, NSR Lite, GSR, and BSR devices.

**NSR**

The NSR built-in switch ports are SFP0, SFP1, BACKPLANE0 and BACKPLANE1. The NSR also supports network expansion cards. By factory default, the SFP0, BACKPLANE0, and the network expansion card ports are in VLAN 1; the SFP1 and BACKPLANE1 are in VLAN2.

The network expansion cards need to be placed in the front three slots to reach the Nodegrid OS.

**NSR Lite**

The NSR Lite doesn’t have a built-in switch, but it supports network expansion cards. The switch ports are connected to the OS via a tunnel interface BACKPLANE0. The network cards need to be placed in the front 3 slots, and If more than one network expansion card is present, they need to be in consecutive slots.

**GSR**

The GSR has a built-in 8-port switch, BACKPLANE0 and BACKPLANE1. The first four ports also support PoE.

**BSR**

The BSR has a built-in 4-port switch and BACKPLANE0.
