Port Adapters
X.25 Support
X.25 packet-switched support is provided by the operating software that is bundled with the
Cisco IOS software image. The operating software provides both the link and packet level facilities
of the 4T port adapter.
The operating software is accessed via a VT100 terminal connected to the console port of the
Input/Output controller. The settings of the terminal should be as follows:
•
Baud: 9600
•
Data bits: 8
•
Parity: none
•
Stop bits: 1
To boot the software, type the following command at the “>” prompt:
> b flash
(The software will now boot from Flash memory.)
Safety Information
Following are safety instructions for installing the 4T port adapter in a Cisco 7200 series router.
Failure to install the 4T port adapter in accordance with these instructions will invalidate the
approval.
•
The 4T port adapter contains Safety Extra-Low Voltage (SELV) circuitry. Ensure that
attachments at the interconnection ports of the apparatus are also SELV circuits. (SELV circuits
are so designed and protected that, under both normal conditions and a likely fault condition, the
voltage that can be drawn is not hazardous.)
•
Always disconnect the chassis from the power supply before removing any covers.
•
Always disconnect the host product chassis from any analogue telephone circuits or ISDN
(where applicable) before removing any covers.
If you have any doubt as to how to safely install the 4T port adapter correctly in a Cisco 7200 series
router, please seek advice from a qualified telecommunications engineer.
Power Requirements
The power requirements of the 4T port adapter are as follows:
•
+5 VDC/2000mA
•
+12 VDC/120mA
•
–12 VDC/120mA
It is important to ensure that the power drawn by the apparatus, together with any auxiliary
apparatus, lies within the rating of the host power supply.
Approvals
The 4T port adapter has received approval from Nihon Cisco Systems K.K. of Japan. The approval
number is N96-K058-0.
