Equinox ESP-2 OPTO Serial Hub Installation and User Guide
To install the ferrite core:
1. Open the ferrite case and thread the network cable through the center so that the
ferrite is approximately 1-2 inches from the plug.
2. Wrap the other end of the cable around the ferrite casing to thread it through a
second time.
3. While stretching the cable to create a snug fit, carefully bring the other side of the
ferrite case over and snap it in place. Be careful to avoid crimping or squeezing
any part of the cable.
Use of the ferrite core is the responsibility of the user. The ESP-2 OPTO hub
generates, uses and may radiate radio frequency energy and, if not used in accordance
with these instructions, may cause harmful interference to radio communications.
2.6 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-2 hub. The hub stores nonvolatile data such as SNMP community name,
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
on page 23) or the configuration utility (see
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
on page 22) or the configuration utility (see
