        ESP-4 MI Serial Hub Installer/User Guide

Table 2.7 indicates when each type of change takes effect.

Changing a web interface/configuration utility password takes effect the next time the web 
interface or the configuration utility is accessed.

Reinitializing and Resetting the Hub

The information in this section is not a standard part of the startup sequence; however, it is 
provided for reference if the serial hub must be reinitialized or reset.

Reinitializing

The INIT

 

button on the front panel may be used to remove configured information from an ESP-4 

MI hub. The hub stores nonvolatile data such as the SNMP community name, admin password, 
system contact and IP address in the EEPROM. This information is erased by pressing and holding 
the INIT

 

button until reinitialization occurs.

When the INIT button is first pressed, the 

ON LINE 

LED will begin to blink to confirm that you 

have pressed the INIT

 

button. As the INIT

 

button remains pressed, the 

ON LINE 

LED will blink at 

a faster rate. After approximately 12 seconds, the 

ON LINE 

LED will turn off. At this point, all 

nonvolatile information will be reset to the factory defaults and the hub will immediately reboot.

You may also reinitialize the hub using the web interface (see 

Reinitializing the Hub

 on page 34) or 

the configuration utility (see 

Reinitializing the Hub

 on page 42).

Resetting

The RESET

 

button on the front panel may be used to reset the serial hub. Pushing this button will 

cause an immediate reboot. You may also reset (reboot) the hub using the web interface (see 

Rebooting the Hub

 on page 33) or the configuration utility (see 

Rebooting the Hub

 on page 42).
