Stacking Units 29Rules For StackingUnitsThis information is also provided in the user documentation thataccompanies the Cascade Kits.■ The number of Switch units in a stack is limited to a maximum of 192front panel ports in the stack.■ Only one Cascade Module can be installed per Switch. If CascadeModules are fitted to both expansion slots in a Switch then bothModules will be disabled.■ Cascade Modules are NOT hot-swappable or hot-insertable. Ensurethat the Switch is powered off before inserting or removing a CascadeModule.■ The Cascade Extender Unit is hot-insertable. This allows its hostSwitch unit to be removed and replaced without disturbing the rest ofthe stack.■ Only 3Com Cascade Cables can be used to connect between CascadeModules/Cascade Extender Units.■ Due to the length of the Cascade Cables, you must insert all of theCascade Modules into Expansion Module Slot 1 or all of the CascadeModules into Expansion Module Slot 2 on the Switches.■ It is not possible to stack the Switch 4400, Switch 4400 SE andSwitch 4400 PWR with other SuperStack II or SuperStack 3 productsusing the Cascade Stacking Kit (3C17227) or Cascade Extender Kit(3C17228).The Switch 4400 PWR can be stacked with all other Switch 4400 Seriesswitches.■ 3Com strongly recommends that you upgrade all Switch 4400 units(24-port and 48-port) in a stack to the latest software agent.■ 3Com recommends that you initialize a Switch 4400,Switch 4400 PWR or Switch 4400 SE unit that has previously beenused elsewhere in your network before you add it to an existing stack.If you do not initialize the unit, problems may be caused by conflictingSwitch configurations.■ When the Switch 4400s are stacked together they are assigned a unitnumber from bottom-to-top for management purposes. When furtherSwitches are added to the stack, they can be positioned at the bottomof the stack or at the top. Either way, the Switch managementsoftware will re-order the Switch unit numbers into a logical orderagain (from bottom to top).DUA1720-3AAA05.book Page 29 Friday, March 7, 2003 11:53 AM
