Cisco ISA 3000 Industrial Security Appliance Hardware Installation Guide
Chapter 1 Product Overview
Hardware Overview
Reset Button
The Reset button resets the security appliance configuration to the default configuration set by the
factory. To restore the security appliance configuration to the default configuration set by the factory,
use a standard size #1 paper clip with wire gauge 0.033 inch or smaller and simultaneously press the
reset button while applying power to the security appliance.
When depressed the pushbutton follows these actions:
• Depressed 0 to < 3 seconds or > 15 seconds — No action is taken.
• Depressed > 3 seconds < 15 seconds — After reboot, the unit will be running the original factory
default configuration.
Note The new configuration will not take effect until after a reboot. The system will boot with the original
factory default configuration, including ROMMON variables. Check the software guide for the operating
system you are running for the ability to change these variables.
Power Supply
The Cisco ISA 3000 comes with redundant external power connector. the connector supports 12 - 48
VDC. The connectors are Molex 5.00mm Pitch Eurostyle™ Horizontal Plug, with Retention Screws.
The power supply does not support reverse polarity, but does have reverse polarity protection. This
means if you reverse + & - connections, the system will not power on but there will be no damage.
The + terminal always has to be greater than the - terminal for the system to operate. The difference is
in the system grounding scheme used.
The ISA 3000 supports 3 basic schemes:
• Isolated DC in, neither + nor - terminal is tied to chassis GND
• Positive DC in, negative (-) terminal is tied to chassis GND
• Negative DC in, positive (+) terminal is tied to chassis GND
Note To ensure uninterrupted operation the redundant power connections must be connected to independently
separated power sources.
1 GB Removable SD Flash Memory Card
The Cisco ISA 3000 has a removable SD flash memory slot (referred to as SD). This is primarily to allow
easy updates, copying of logs and crash-dumps.
The device does not come with a removable SD flash memory card installed, this is an optional spare
item, Cisco part number SD-IE-1GB=.
Note Check the software guide for the operating system you are running for information on SD memory
support.
