eNB Installation
================
This section describes how to install and configure the Sercomm eNB
which is the default eNB device for Aether/Pronto project.

.. _enb-installation:

Preliminaries
=============
Prepare the following devices:

* Sercomm eNB
* 10GbE SFP+ to 1/10GbE copper media converter
* Workstation to remotely access and configure the eNB

Collect the following information:

* eNB IP address
* MME IP address (10.168.0.6 by default)
* TAC
* Cell ID

.. warning::

  ``Cell ID`` and ``TAC`` are critical parameters and the values must
  be assigned the by OPs team.

Connect the eNB
===============

Connect the eNB to the fabric switch through the media converter and power on,
then it will automatically get pre-configured IP address using DHCP.
Verify that you can access the web-based configuration(`https://<eNB IP>`) from your workstation.
If the eNB address is not directly reachable, use the management server as a jump host.

The default credentials for the Sercomm eNB are:

* Username: ``sc_femto``
* Password: ``scHt3pp`` (or ``sc_femto``)
