Removing a T1600-SIB

Five SIBs are installed in the router. The SIBs are located in the rear of the chassis in the slots marked SIB0 through SIB4. Each T1600-SIB weighs approximately 6.5 lb (3 kg).

To remove the SIBs (see Figure 1):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3. Loosen the captive screws (using a Phillips (+) screwdriver, number 2) on the ejector handles on each side of the SIB faceplate.
4. Flip the ejector handles outward to unseat the SIB.
5. Grasp both ejector handles, pull firmly, and slide the SIB about three-quarters of the way out of the chassis.
6. Place one hand underneath the SIB to support it and slide it completely out of the chassis. Place it on the antistatic mat.

   Caution: Do not stack hardware components on one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.

Installing a T1600-SIB

Each T1600-SIB weighs approximately 6.5 lb (3 kg). To install a T1600-SIB (see Figure 2):

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. Place one hand underneath the T1600-SIB to support it. With the other hand, hold one of the ejector handles on the T1600-SIB faceplate.
3. Carefully align the sides of the T1600-SIB with the guides inside the chassis.
4. Slide the T1600-SIB into the chassis, carefully ensuring that it is correctly aligned.
5. Grasp both ejector handles and press them inward to seat the T1600-SIB. Ensure that the ejector handle tabs are properly mated inside their corresponding chassis slots. You might have to close and open the handles a few times before the tabs catch the slots.
6. Tighten the captive screws on the ejector handles.

7. Bring the T1600-SIB online using one of the following methods:

   • Press and hold the ONLINE/OFFLINE button on the T1600-SIB faceplate. The green OK LED on the faceplate begins to blink. Hold the button down until the LED blinks.
   • Issue the following CLI command on the router:

Verifying the Installation of a T1600-SIB

To verify that the T1600-SIB is functioning normally:

1. Check the LEDs on the T1600-SIB faceplate.
   • The green OK LED should light steadily a few minutes after the T1600-SIB is installed.
   • If the FAIL LED is lit steadily, remove and install the T1600-SIB again. Make sure that the T1600-SIB is seated properly. If the FAIL LED still lights steadily, the T1600-SIB is not functioning properly. Contact your customer support representative.
2. Verify that four T1600-SIBs are in the Online state and one SIB is in the Spare state. Display the status of the T1600-SIB by issuing the show chassis sibs command:
   
   

   user@host> show chassis sibs

    Slot  State               Uptime
    0    Spare            0 days, 30 minutes, 12 seconds
    1    Online           0 days, 25 minutes, 45 seconds
    2    Online           0 days, 20 minutes, 28 seconds
    3    Online           0 days, 15 minutes, 7 seconds
    4    Online           0 days, 10 minutes, 52 seconds

   To bring a T1600-SIB online, issue the request chassis sib online operational mode command.
