Removing the M320 SIBs
Two to four SIBs are installed in the router. The SIBs are located in the rear of the chassis in the slots marked SIB0 through SIB3. SIBs are hot-insertable and hot-removable. Each SIB weighs approximately 4 lb (1.8 kg).
To remove a SIB (see Figure 1):
- Place an electrostatic bag or antistatic mat on a flat, stable surface.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site. For more information about ESD, see Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series Router.
- Loosen the captive screws (using a Phillips (+) screwdriver, number 2) on the ejector handles on each side of the SIB faceplate.
- Flip the ejector handles outward to unseat the SIB.
- Grasp both ejector handles, pull firmly, and slide the SIB about three-quarters of the way out of the chassis.
- 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.
