Installing a T320 SIB

To install a SIB into the rear of the chassis (see Figure 1):

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.
