Tools and Parts Required for Converting a T640 Routers
To convert a T640 router, you need the following tools:
- Phillips (+) screwdriver, number 2
- Electrostatic discharge (ESD) grounding wrist strap
You can order a T640 router with the hardware and software components already installed, or you can convert your existing T640 router by ordering and installing a kit that contains these hardware components:
- One rear fan tray with eight fans
The rear fan tray required for the converted T640 router contains eight fans (the fan tray being replaced has five blowers).
- One or two T-CBs
Figure 1 and Figure 2 illustrate the difference between a T-CB and a standard CB.

Figure 2: T640 Router Standard CB
- Five T640-SIBs
If your T640 router already contains T-CBs and the new rear fan tray, but contains standards SIBs, you can order and install a kit that contains only T640-SIBs. Figure 3 and Figure 4 illustrate the difference between a T640-SIB and a standard SIB or SIB version B.
