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
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.
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
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.
