Installing a T640 LCC-CB
To install an LCC-CB (see Figure 148 on page 313):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
2. Carefully align the sides of the LCC-CB with the guides inside the chassis.
3. Slide the LCC-CB into the chassis, carefully ensuring that it is correctly aligned.
4. Grasp both ejector handles, and press them inward to seat the LCC-CB.
5. Tighten the captive screws on the ejector handles, using a Phillips (+) screwdriver,
number 2.
6. Verify that the LCC-CB is functioning normally:
•
Check the LEDs on the LCC-CB faceplate. The green OK LED should light steadily
a few minutes after the LCC-CB is installed. If power is applied to the Routing Engine
and its corresponding LCC-CB is functioning normally, the LCC-CB comes online
automatically.
If the FAIL LED is lit steadily, remove and install the LCC-CB again. If the FAIL LED
still lights steadily, the LCC-CB is not functioning properly. Contact your customer
support representative.
•
Use the show chassis environment cb command to check the status of the LCC-CB.
