Removing a TX Matrix TX-CB

250
To remove a TX-CB (see Figure 107 on page 250):
Take the host subsystem offline. See "Taking a TX Matrix Host Subsystem Offline"
1.
on page 247.
CAUTION: Before you replace a TX-CB, you must take the host subsystem
offline. If there is only one host subsystem, taking the host subsystem
offline shuts down the TX Matrix router.
CAUTION: If the TX-CB to be replaced is associated with the Routing
Engine currently functioning as the master Routing engine, switch it to the
backup before removing the TX-CB.
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
3.
the strap to one of the ESD points on the chassis.
Loosen the captive screws (using a Phillips (+) screwdriver, number 2) on the ejector
4.
handles on both sides of the TX-CB faceplate.
Flip the ejector handles outward to unseat the TX-CB.
5.
Grasp the ejector handles and slide the TX-CB about halfway out of the chassis.
6.
Place one hand underneath the TX-CB to support it, and slide it completely out of the
7.
chassis.
Place the TX-CB on the antistatic mat.
8.
If you are not replacing the TX-CB now, install a blank panel over the empty slot.
