Important File Locations
The SERIMUX has several files that are important for administrative use. Below is a brief listing of some files that the root user or
system administrator might desire to either monitor or edit.
Default Script
The default script file is executed whenever the SERIMUX is booted. The file is /usr/rc.user and can be modified with the vi editor.
The modified script becomes effective when the system is rebooted.
Booting Sequence
When the SERIMUX boots, it uncompresses the /cnf/cnf.tar.gz file to /tmp/cnf/* and unmounts the /cnf file. If the configuration files
are modified in the /tmp/cnf file and the configuration is saved to flash (saveconf), the unit mounts the /cnf file and compresses the
/tmp/cnf/* to /cnf/cnf.tar.gz.
User Storage Space
The SERIMUX comes with 1 megabyte of user storage space. This storage space can be used to store custom scripts. The
location is /usr2.
System Administration
Introduction
This chapter describes how to perform tasks performed either by root or the system administrator. These tasks fall under the
general heading of system administration and include firmware upgrades, resetting the unit to defaults, and disaster recovery
procedures.
Upgrading the Firmware
Web Interface
It will be necessary to download the latest firmware version to a system on the same subnet as the SERIMUX. The latest firmware
can be downloaded from the SERIMUX support site at: http://www.nti1.com. Do the following to upgrade the firmware:
1. Access the web interface.
2. Under the System administration heading, choose Firmware upgrade.
3. Choose the Browse button and locate the firmware download.
4. Choose Upgrade. The SERIMUX will automatically reboot when the upgrade is complete.

Resetting Factory Defaults
There are two ways to reset the unit to the factory defaults. The quickest and simplest method is to push and hold the hardware
factory default reset button until the Ready light on the front panel goes out. The reset button is located on the back panel of the
unit next to the Ethernet port.
