4 Document Limitations Procedure assumes: New chassis has been ordered and has been received from Cisco.
5 Typical Replacement Team & Execution Chassis replacement requires at least two people minimum, with three people as optimum.One person to coordinate the switch chassis hardware setup, IOS configuration, chassis installation activation monitoring and if needed activation changes.Two people to coordinate switch label preparation and chassis installation.Chassis replacement outage with new supplies and additional new cards, typically so far has taken two hours to complete.Schedule outage for 2.5 to 3.0 hours and send outage change control.Outage notification should include link to Switch ports, should NCAB & NNAG individuals a specific map of the outage area.PTT feature: is handy trouble shooting featureIn the larger cities coverage appears good.Internal building coverage: would be a problem with any service.Nationwide inconsistent: Not many mid sized cities covered.Rural coverage: nonexistent and highly traveled corridors very few covered.Roaming: Nonexistent

7 New Switch Chassis Preparation Unpack (But leave on delivered pallet)Mount rack ears if not already.Do not install supplied cable management under rack ears, unless installing chassis where no rack cable management is provided.Install Fan BladeLabel ChassisSwitch IDSlot ID’sInstall any new cards at final locations in chassis if part of up-grade.Do not install new power supplies yet, if part of up-grade.Deliver Chassis and supplies to switch up-grade location.
8 Prior to outage Save switch configuration to flash Optional: Print a copy of switch port configuration, from the NETS port lists.Have during chassis replacement.
10 Chassis Replacement Call NOC before starting work. Shut off power supplies.Start removing cables from the top of the switch and working toward the bottom.Be careful to keep fiber ends clean.Remove the chassis rack screws.Do Not remove the lower screws in the chassis tray.Remove the chassis ground cable.Remove the switch power supplies.Secure all cables back so cards and switch can be removed from tray.
11 Chassis ReplacementWith non E chassis switch still in rack in it’s tray, set up static system and transfer cards to new E-chassis in same slot positions.Install new E-chassis with cards in rack tray.Secure new E-chassis with rack screws.Install power supplies and chassis ground cableStart installing cables from the bottom of the switch and working toward the top.
12 Chassis Replacement & Power-up Have second person verify re-cabling.Setup boot monitor via the console or Network and power-up.If needed upon boot completion, update switch configuration for any new card changes during up-grade.Monitor to see if POE devices, VOIP and AP’s, come up.Call the NOC to verify, Nagios for active alarms related to closet.Reply to Outage Notice that work is complete.
14 Post ReplacementVerify all up-graded switch cabling is re-managed and management covers are in place.Clean up floor of any debris and remove any unnecessary tools or documents.Place the old chassis and power supplies on the empty E-chassis shipping pallet and transport non E-chassis and hardware back to ML-34, for trade in.
