installation instructions (or field upgrade kit). Figure 1-1 will help you determine
if your chassis requires a filed upgrade kit to install an extended-format module
into the bottom slot. The illustration shows the 4-Slot chassis but is also applies
to the 8-Slot chassis. Chassis with two separate shielding strips in the bottom
slot require the upgrade kit to install the FDDILink module; chassis with one
shielding strip do not.
Figure 1-1
Determining the Need for a Field Upgrade Kit
Preparing for
Installation
To prepare to install an FDDILink module into the NETBuilder II system, follow
these steps:
CAUTION:
Take great care to keep the transceivers clean and dust free. Do not
remove the plastic protectors from the board or the end caps from the cable
until you are ready to connect. Immediately install protectors and end caps after
disconnecting.
1
Observe appropriate electrostatic discharge (ESD) precautions.
ESD can damage circuit board components. Failures resulting from ESD may not
be covered under your warranty. To prevent ESD:
■
Keep the module in its antistatic shielded bag until you are ready to install it.
■
Keep the optical transceivers in place until connecting a cable.
■
Do not touch pins, leads, or solder connections on the board.
■
Handle the board by the edges only.
■
Store or ship the module in static-protective packaging.
Observe proper grounding techniques when handling the module: Use a foot
strap and grounded mat, or wear a grounded static discharge wrist strap.
2
Inspect the module for shipping damage.
If you find any damage, contact the shipping company to file a report. If the
module must be returned to your network supplier, ship it in its original
shipping carton. If the original carton was damaged in shipment, repack the
system in a carton that provides equivalent protection.
