Checking the Installation
Step 7 Attach network interface cables or other connection equipment to the interface ports. (See Figure 12).

Step 8 Check the status of the interfaces as follows:
•If this installation was a replacement TRIP, use the show interfaces or show controller [type] command to verify that the system has acknowledged the new interfaces and brought them up.
•If the interfaces are new, use the configure command or the setup command facility to configure the new interface(s) (this does not have to be done immediately, but the interfaces will not be available until you configure them).
Checking the Installation
The TRIP contains one enabled LED and a row of three LEDs for each Token Ring interface. (See Figure 11). The row of three LEDs indicate the speed (4 or 16 Mbps) of the interface and whether the interface is inserted in the ring.
When you install the TRIP in an interface processor slot and turn ON the power (if the power was turned off), the following events occur:
•The enabled LED lights to indicate that the TRIP is operational and that it is powered up. It does not mean that the interface ports are functional or enabled. An error condition exists if the TRIP’s enabled LED is not lit after power up or after initialization. If this happens, check that the TRIP is installed correctly. If a second power up attempt also fails, contact a customer service representative.
•The horizontal set of LEDs flash for about four or five seconds and are then turned off. These LEDs are turned on again after you configure each Token Ring interface as described in the section “Configuring the Interfaces” on page 20.
