Following are the requirements for forming trunk groups:
v All ports in a trunk group must belong to the same port group. For example, to
v You can use from 1–8 ports in a port group to form a trunk.
v Ports must be running at the same speed.
v Ports must be configured for the same distance.
v Ports must have the same encryption, compression, QoS, and FEC settings.
v Trunk groups must be created between switches (or adapters in the case of
v There must be a direct connection between participating switches.
For full details on trunking requirements and configuration, refer to theFabric OS
Administrator's Guide.

Precautions specific to the blade

This topic describes how to remove and replace a port or extension blade.

or a bench ground.
reserved for CR32-8 blades. These blades cannot be installed in other slots as
guide pins and connectors in each slot allow only specific blade types.
CAUTION:
For safety reasons, the ESD wrist strap should contain a series 1
megaohm resistor.
CAUTION:
If you do not install a module or a power supply in a slot, you must
keep the slot filler panel in place. If you run the chassis with an
uncovered slot, the system will overheat.
CAUTION:
Static electricity can damage the chassis and other electronic devices.
To avoid damage, keep static-sensitive devices in their static-protective
packages until you are ready to install them.
CAUTION:
Before plugging a cable into any port, be sure to discharge the voltage
stored on the cable by touching the electrical contacts to ground
surface.
CAUTION:
To avoid damaging blade and chassis, do not use ejector handles to
push the blade into or pull the blade out from a slot.
