FDDI Dual-Attached Intelligent Module User’s Guide Page 6-1CHAPTER 6ADDING/SWAPPING MODULESOnce you have received your ATX, you may want to add a new module toexpand your network bandwidth, replace a module with a module of adifferent type, or swap a module with another module of the same type . Ifyou are:• Adding a 3F00-01 or 3F55-01 to a previously vacant slot or to a slotthat had a different type of module (which includes replacing a3F00-01 with a 3F55-01), see Adding a 3F00-01 or 3F55-01 below,for instructions.• Replacing a 3F00-01 with another 3F00-01 or replacing a 3F55-01with another 3F55-01, see Swapping a 3F00-01 or 3F55-01 forinstructions.The 3F00-01and 3F55-01 can be installed in any slot and you can installmultiple modules in an ATX.6.1 UNPACKING THE SWITCH MODULEUnpack the 3F00-01 or 3F55-01 carefully, handling it by the edges only,and inspect it for possible damage. If any damage is evident, contactCabletron Systems Global Call Center. Save the original container andantistatic wrap in case the module needs to be repaired.6.2 ADDING A 3F00-01 OR 3F55-01If the module you are adding is different from the type of module that wasin the slot earlier, or if the slot was vacant, you have to reboot the ATX soit will recognize the new module. (Replacing a 3F00-01 with a 3F55-01 isconsidered replacing a module of a different type.)If the module you are adding has a different number of ports than themodule you are removing, before you can power cycle the ATX, youmust:• Delete all static addresses• Delete all ARP addresses and IP routing table entries• Delete all filters
