2 Token Ring Interface Processor (TRIP) Installation and Configuration
Product Description
Product Description
This section contains a detailed description of the Token Ring interface processor (TRIP). The TRIP,
shown in Figure 1, provides two or four Token Ring ports for interconnection with IEEE 802.5 and
IBM Token Ring media. The TRIP uses the IBM 16/4-Mbps chipset with an imbedded performance
enhanced interface driver and 16.7 MHz bit slice processor for high speed processing. The speed on
each port is set independently with a software command for either 4 or 16 Mbps. The TRIP firmware
(microcode), which contains card-specific software instructions, resides in a ROM in socket U41.
You may need to replace this component in the future to enable new features or enhancements (if so,
replacement instructions will be provided with the replacement component in an upgrade kit). The
TRIP and all other interface processors support online insertion and removal (OIR), which allows
you to remove and install a TRIP while the system is operating, without shutting down system
power.

Note
The interface processor metal carrier contains the printed circuit board for the TRIP. To
prevent electrostatic damage (ESD), we recommend that you never remove or separate the printed
circuit board from the metal carrier.
circuit board from the metal carrier.
Interface processor slots are accessed from the rear of the chassis. The TRIP can be installed in any
available interface processor slot. Each port on the TRIP requires a media access unit (MAU) to
connect the DE-9TRIP connectors to the external Token Ring networks.

TRIP LEDs
The enabled LED light on the TRIP lights to indicate the following status of the TRIP:
•
Enabled for operation
•
Correctly connected to the backplane
•
Receiving power
•
Contains a valid microcode version
If any of these conditions is not met, or if the initialization fails for other reasons, the Enabled LED
does not light.
