|  | Reset Button | > ❌ **Warning**
> ❌
> ❌ This button is intended for use by Infoblox technicians only.
> ❌ To reset the appliance to default factory settings, follow the procedure in *[Resetting the B1-105](https://infoblox-docs.atlassian.net/wiki/spaces/DeployBloxOneAppliance/pages/43778289)*. |
|  | USB Ports | Only used for configuration update and factory reset. |
|  | LAN2 Port | A 10/100/1000-Mbps gigabit Ethernet port that connects the appliance to the network. You must use the LAN2 port to set up the appliance initially. After the initial setup, you can use both the LAN1 and LAN2 ports in your configuration. On the Infoblox Portal, the LAN2 port appears as **enp1s0**. |
|  | LAN1 Port | A 10/100/1000-Mbps gigabit Ethernet port that connects the appliance to the network. You cannot use the LAN1 port to connect your appliance in the initial setup. However, you can use the LAN1 port in your configuration once the appliance is up and running. On the Infoblox Portal, the LAN1 port appears as **enp2s0**. |
|  | Power/Status LEDs | Top LED = HDD status; Blinking amber = connectivity is good
3G LED: Not being used
Bottom LED = Power status; solid green = power is on |
|  | On/Off Switch | A power switch to turn the power supply on and off. The switch is green when power is on; it is red when appliance is connected to power but not switched on.
To power off the appliance gracefully, press the On/Off switch and release it quickly.
To force the appliance to power off, press the On/Off switch and hold it down until the appliance is off. |

|  | HDMI and VGA Port | The port for connecting your monitor to the B1-105 appliance. Note that connecting a monitor to the appliance is optional. |
|  | COM1/COM2 Console Port | Only use COM1. A male DB-9 serial port for a console connection.
Should you need to use a USB-to-Serial adapter to carry a serial connection over a USB port in a computer that lacks a 9-pin serial interface, use a properly grounded USB-to-Serial dongle to connect to the serial console port. If the dongle connects to a laptop, the laptop must be grounded properly as well. Failure to do so may result in damage to the serial console port of the Infoblox appliance. Infoblox is not responsible for such damage. |
|  | DC_IN | An AC to DC power input jack to which you connect the power cable of the AC to DC adaptor that ships with the appliance. Note that using an incompatible adaptor or cable, or improperly connecting the adaptor or cable may cause damage to the appliance. |
# B1-105 Ethernet Port LEDs
To see the link activity and connection speed of an Ethernet port, you can look at its Activity and Link LEDs. The following figure shows the status the LEDs convey through their colors and illumination (steady glow or blinking).

| --- | --- | --- |
| **Label** | **Color** | **Port Status** |
| Activity | Blinking Yellow | Link is up and active |
| | Off | Link is down |
| Link | Steady Amber | 1000 Mbps |
| | Steady Green | 100 Mbps |
| | Off | 10 Mbps |
# B1-105 Interface Connector Pin Assignments
The B1-105 appliance has three types of ports:
- USB port (reserved for future use)
- Male DB-9 console port pinout
- Two RJ-45 Ethernet port pinout
The DB-9 and RJ-45 connector pin assignments are described below. The DB-9 pin assignments follow the EIA232 standard. To make a serial connection from your management system to the console port, you can use an RJ-45 rollover cable and two female RJ-45-to-female DB-9 adapters, or a female DB-9-to-female DB-9 null modem cable. The RJ-45 pin assignments follow IEEE 802.3 specifications. All Infoblox Ethernet ports are auto-sensing and automatically adjust to standard straight-through and cross-over ethernet cables.
