Connecting a PC to the TCM Ethernet port
Before replacing any board, a PC must be connected to the primary TCM Ethernet port,
or, if the primary TCM has failed, to the secondary TCM Ethernet port. This PC is used
to capture system information and diagnostic data.
1. Set up a HyperTerminal connection on a PC Ethernet network port to communicate
with the TCM.
2. Connect the PC Ethernet network port configured for use by the HyperTerminal
program to the TCM Ethernet port with an Ethernet cable.
3. Start HyperTerminal, and activate the HyperTerminal Capture Text facility to
capture the entire debug port session.
4. Log on to the Ethernet port as a maintenance level user (exclusive user).
Refer to Appendix C. on page 125 if you are unfamiliar with HyperTerminal.
TCM board replacement procedures
This section describes procedures for replacing TCMs.
Attention: Refer to safety notices before starting an installation.
Attention: Use a properly attached ESD wrist strap when handling any
TFIO, TSW, or TCM module, otherwise damage to equipment may result.
Attention: Be sure the ONLINE LEDs on both TCMs are lit before
removing and TCM from the system. This ensure system redundancy
and no loss of data or improper operation of the system.
