Replacing a T320 SIB

 

To replace a SIB, perform the following procedures:

  1. Removing a T320 SIB

  2. Installing a T320 SIB

Removing a T320 SIB

Three SIBs are installed in the router. The SIBs are located in the rear of the chassis in the slots marked SIB0 through SIB2. Each SIB weighs approximately 4.5 lb (2.0 kg).

To remove a SIB (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. For more information about ESD, see Preventing Electrostatic Discharge Damage to a T320 Router.
  3. Press the online/offline button on the SIB faceplate. Press and hold down the button until the green OK LED goes out (about 5 seconds).
  4. Loosen the captive screws (using a Phillips (+) screwdriver, number 2) on the ejector handles on each side of the SIB faceplate.
  5. Flip the ejector handles outward to unseat the SIB.
  6. Grasp both ejector handles, pull firmly, and slide the SIB about three-quarters of the way out of the chassis.
  7. 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 T320 SIB

To install a SIB into the rear of the chassis (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. For more information about ESD, see Preventing Electrostatic Discharge Damage to a T320 Router.
  2. Place one hand underneath the SIB to support it. With the other hand, hold one of the ejector handles on the SIB faceplate.
  3. Carefully align the sides of the SIB with the guides inside the chassis.
  4. Slide the SIB into the chassis, carefully ensuring that it is correctly aligned.
  5. Grasp both ejector handles and press them inward to seat the SIB.
  6. Tighten the captive screws on the ejector handles.
  7. Press the offline/online button until the green OK LED blinks to bring the SIB online.
  8. To verify that the SIB is functioning normally, check the LEDs on its faceplate. The green OK LED should light steadily a few minutes after the SIB is installed. If the FAIL LED is lit steadily, remove and install the SIB again. If the FAIL LED still lights steadily, the SIB is not functioning properly. Contact your customer support representative.
