Attention: Refer to safety notices before starting an installation.
Attention: This procedure requires that all Upper Fan assemblies (and if installed,
external cabinet fans ) are removed from the SAN256N director chassis. The SAN256N
system must be shut down during the TMF/TFD module replacement to prevent the
internal SAN256N modules (TFIO, TCM, and TSW) from being subjected to higher than
recommended operating temperatures.
Attention: Use a properly attached ESD wrist strap when handling the TMF/TFD
module, otherwise damage to equipment may result.
