Product Details
Figure 2 shows the front panel of the Cisco 3850 series 12 ports switch.
Note：
| ① | UID (blue beacon) | ⑤ | USB Type A storage port |
| ② | Mode button | ⑥ | 12 ports of SFP |
| ③ | Status LEDs | ⑦ | Network SFP uplink module slot |
| ④ | USB mini-Type B (console) port | ||
·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.
