Product Details
Figure 2 shows the front panel of the Cisco 3850 series 12 ports switch.
Note：
① UID (blue beacon) ② Mode button ③ Status LEDs ④ USB mini-Type B (console) port ⑤ USB Type A storage port ⑥ 12 ports of SFP ⑦ Network SFP uplink module slot
·The status LEDs include STAT (status), DUPLX (duplex), SPEED, STACK, SYST (system), ACTV (active) and S-PWR (Stack Power).
·The switch supports one hot-swappable network module that provides uplink ports to connect to other devices. The switch should only be operated with either a network module or a blank module installed.
Figure 3 shows the back panel of the WS-C3850-12S-S switch.
Note：
① Ground connector ② CONSOLE (RJ-45 console port) ③ Fan modules ④ MGMT port ⑤ UStackWise port connectors ⑥ StackPower connectors ⑦ Power supply modules
Figure 4 shows the StackWise-480 and StackPower connectors.
In order to stacking with LAN base feature set, WS-C3850-12S-S needs to configure in LAN base mode from CLI.
