Removing a T640 Standard SIB or Standard SIB Version B
NOTE: If you are upgrading to standard SIB version B or T640-SIBs, see
“Upgrading to a T640 Standard SIB Version B” on page 427 or the TX Matrix
Router Hardware Guide for T640-SIBs before removing the SIBs.
To remove a standard SIB or standard SIB version B (see Figure 227 on page 426):
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. 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.
