CRS112-8P-4S-IN


The CRS112 is a network switch with eight-gigabit Ethernet ports and four SFP ports. It is already configured, with all ports switched together. We recommend you to set up a password to secure your device. This unit is compatible with 1.25G SFP modules. The CRS112-8P is capable of powering other devices through PoE.

Quick start

The Default configuration, Switch mode all interfaces are switched; LAN Configuration. All ports bridged with IP 192.168.88.1/24 set on the bridge.

  • Place on the flat surface (see "Mounting").
  • Connect your PC to any Ethernet port.
  • Connect the power adapter to the DC jack.
  • Set IP for you PC to 192.168.88.2
  • The Initial connection has to be done via the Ethernet cable, using the MikroTik Winbox utility or Web browser.
  • Use Winbox or Web browser to connect to the default IP address of 192.168.88.1 from any port, with the username admin and no password.
  • We recommend clicking the "Check for updates" button and updating your RouterOS software to the latest version to ensure the best performance and stability. The device needs to have an active internet connection.
  • To manually update the device go to our webpage and download the latest software version packages.
  • Open Winbox and upload them to the Files menu.
  • Reboot the device.
  • Set up your password to secure the device.

Powering

The device has two direct-input power jacks (5.5 mm outside and 2 mm inside, female, pin positive plug). One DC input supports 48-57 V DC, the other supports 18-28 V DC. Only a 28 V PSU is included. You can use either one or both inputs at the same time. This will also affect the PoE output functionality (see below section). The power consumption of this device itself under maximum load is up to 12 W.

PoE output

This device can supply PoE powering to external devices from its Ethernet ports. The output voltage will be selected automatically, depending on what kind of adapter is connected, and what kind of voltage the connected device requires. The device can power 802.3af/at devices, but a 48 V PSU must be acquired separately. By default the PoE mode is set to auto, it will not damage non-PoE devices and will auto-detect devices with PoE support and the needed voltage. Once a PoE device is detected, it will be powered and the PoE LEDs will turn on. With the included 28 V PSU the max power output of each Ethernet port in this mode is 1 A, the total maximum for all ports is 2.8 A. At 802.3af/at high power mode the max power output is 450 mA per port, total max 1.4 A.

Configuration

The device is set up as a switch, with 192.168.88.1 as the management IP of the bridge interface. RouterOS includes many configuration options in addition to what is described in this document. We suggest starting here to get yourself accustomed to the possibilities: https://mt.lv/help.

In case the IP connection is not available, the Winbox tool (https://mt.lv/winbox) can be used to connect to the MAC address of the device.
The device is equipped with an RJ45 serial port, set by default to 115200 bit/s, 8 data bits, 1 stop bit, no parity. Standard RJ45 to COM cable can be used, pinout can found in the documentation (see link above).
For recovery purposes, it is possible to boot the device from the network, see the next section.

Buttons and Jumpers

The reset button has these functions:

  • Hold this button during boot time until LED light starts flashing, release the button to reset RouterOS configuration.
  • Keep holding the button for 5 more seconds or until the user LED turns off, then release it to make the RouterBOARD look for Netinstall servers. The first Ethernet port is used for the Netinstall process. See RouterOS documentation about using the Netinstall recovery utility.

Regardless of the above option used, the system will load the backup RouterBOOT loader if the button is pressed before power is applied to the device. This is useful for RouterBOOT debugging and recovery.

LED indicators

  • The Power LED is lit when the router is powered from the DC jack.
  • The user LED can be configured from RouterOS.
  • The square port LEDs indicate the individual Ethernet and SFP port activity.
  • Triangle LEDs indicate PoE out status. Green LED indicates that the respective port uses low voltage, a red LED indicates high voltage. Flashing a single green LED: problem to start a low voltage device. Flashing single red LED: problem with high voltage device. All PoE LEDs flashing: wrong voltage PSU plugged into one of the ports.

Mounting

The device is designed to be used indoors and placed on a flat surface with all needed cables connecting to the front of the unit. If the desired mounting location is a rackmount enclosure, please attach the rackmount mounting brackets to both sides of the device and secure with screws firmly.
Grounding screw is located on the backside of the device case, please connect it accordingly to efficient ground.
When mounting on the wall, please ensure that cable feed is pointing downwards.
The IPX rating scale of this device is IPX0. We recommend using Cat6 shielded cables.

Grounding

The device has a grounding wing nut attached to the back of its case. You can attach a grounding wire to this wingnut and connect it to a grounding bus bar that is typically available in a server room and which is then connected to earth ground.

Operating System Support

The device supports RouterOS software with the version number at or above what is indicated in the RouterOS menu /system resource. Other operating systems have not been tested.
