CHAPTER 2: INSTALLING THE D20MX
Retrofitting the D20MX in an existing D20
To retrofit the VME
chassis and the non-
VME chassis
D20MX INSTRUCTION MANUAL
12.5. Close the core and snap the halves together. See Figure 10.
Figure 10: Closed ferrite clamp
12.6. Visually inspect the installation and confirm that the assembly has completely
latched and that the power cable is not pinched. Also check that none of the
power cable connections have come loose during the installation process.
13. Connect the power supply to the D20 chassis. See section: "Connecting the power
supply" on page 40.
14. Power-up the D20. See Chapter 4, Powering-up and Testing.
15. Start using the D20MX's tools and utilities to configure and monitor the operation of
the D20MX. See Chapter 6, Using the D20MX.
16. Make device and network connections. See Chapter 3, Connecting to Devices and
Networks.
The D20MX processor board can be installed in an existing D20 device to replace D20ME
D20M++, or D20MEII processor boards. If a D20 is being retrofitted, the following limitations
exist:
•
You cannot install multiple D20MX processor boards in a single D20. Therefore, a
maximum of seven serial and two D.20 Link connections are supported on each D20
unit.
•
The D20MX supports 100BASE-FX instead of 10BASE-FL. If you are using any other
devices in your system, and you are limited to 10BASE-FL, you must purchase a
100BASE-FX to 10BASE-FL media converter.
The D20MX can be installed in a VME chassis or a non-VME chassis.
See section: "D20MX upgrade kits" on page 27 for a list of available upgrade kits and the
parts provided within each kit.
1.
Ensure that you are sufficiently grounded to prevent ESD damage to the D20MX or
other components. See section: "Grounding the D20MX" on page 39.
2.
Switch the power off for the D20 chassis.
3.
Remove the D20ME, D20M++, or D20ME II module.
4.
Remove the D20EME module and D20EME Media Interface Card.
5.
Remove the horizontal blank faceplates, including the bottom faceplate.
6.
If the chassis contains a modem card, move the modem card to position 2.
7.
Follow the D20MX "Installation steps" on page 35.
See Figure 11, "Cable to fiber optic daughter card".
Ensure that the cable is not pinched.
