18 Token Ring Interface Processor (TRIP) Installation and Configuration
Installation
Step 5
Place the removed TRIP on an antistatic mat or foam pad, or place it in an antistatic bag if
you will return it to the factory.
Step 6
If the interface processor slot is to remain empty, install an interface processor filler
(MAS7K-BLANK) to keep dust out of the chassis and to maintain proper air flow through
the interface processor compartment.
To help prevent dust and contaminants from entering the chassis, do not leave the interface processor
slot open. Immediately proceed to the section “Installing a TRIP” on page 18.
Installing a TRIP
The TRIP slides into the open interface processor slot and directly to the backplane. The interface
processors are keyed to guide pins on the backplane, so the TRIP can be installed only in an interface
processor slot. (See Figure 5, Figure 6, Figure 7, Figure 8, or Figure 9, depending on your chassis.)
Figure 10 shows the functional details of inserting an interface processor and using the ejectors.
Figure 11 shows proper handling of an interface processor during installation.
Caution
Remove or insert only one interface processor at a time. Allow at least 15 seconds for the
system to complete its discovery and initialization tasks before removing or inserting another
interface processor. Disrupting the sequence before the system has completed it verification can
cause the system to interpret hardware failures.
The TRIP supports ring speeds of 4 and 16 Mbps. Follow these steps to install a TRIP:
Step 1
Ensure the console terminal is connected to the RP (or RSP) Console port and that the
console is turned ON.
Step 2
Hold the TRIP handle with one hand, and place your other hand under the carrier to support
the TRIP and guide it into the slot. (See Figure 11.) Avoid touching the card or any
connector pins.
Caution
To prevent ESD damage, handle interface processors by the handles and carrier edges
only.
Step 3
Place the back of the TRIP in the slot and align the notch on the carrier with the groove in
the slot. (See Figure 10.)
Step 4
While keeping the TRIP parallel to the backplane, carefully slide it into the slot until the
back of the faceplate makes contact with the ejector levers, then stop. (See Figure 10b.)
Caution
Always use the ejector levers when installing or removing processor modules. A module
that is partially seated in the backplane will cause the system to hang and subsequently crash, and
shoving or slamming the interface processor into the slot can damage the backplane and connector
pins.
Step 5
Using your thumbs, simultaneously push both ejectors inward until the TRIP is pushed
entirely into its slot. (See Figure 10c.)
Step 6
Tighten both of the captive installation screws.
