Installing Previously-Configured Systems in a Stack
Ifmemberunitsinastackhavebeenpreviousmembersofadifferentstack,youmayneedto
configuretherenumberingofthestackasfollows:
1. Stacktheunitsinthemethoddesired,andconnectthestackcables.
2. Poweruponlytheunityouwishtobemanager.
3. Oncethemanagementunit
ispoweredup,logintotheCLI,andusetheshowswitch
commandasdescribedin“showswitch”onpage2‐5todisplaystackinginformation.
4. Clearanyswitcheswhicharelistedas“unassigned”usingtheclearswitchmember
commandasdescribedin“clearswitchmember”onpage2
‐11.
5. Powerupthememberofthestackyouwishtobecomeunit2.Oncethesecondunitisfully
powered,theCOMsessionoftheCLIwillstatethatanewCPUwasadded.
6. Usetheshowswitchcommandtoredisplaystackinginformation.
a. Ifthenewmemberdisplaysasunit
2,youcanproceedtorepeatthisstepwiththenext
unit.
b. Ifthenewmemberdisplaysadifferentunitnumber,youmust:
(1) Renumberthestackusingthesetswitchrenumbercommandasdescribedin“set
switch”onpage2‐8,then
(2) Cleartheoriginalunitnumberusingtheclear
switchmembercommand.
7. RepeatStep6untilallmembershavebeenrenumberedintheorderyoudesire.
8. Afterthestackhasbeenreconfigured,youcanusetheshowswitchunitcommand(“show
switch”onpage2‐5)tophysicallyconfirmtheidentityofeachunit.Whenyouenterthe
command
withaunitnumber,theMGRLEDofthespecifiedswitchwillblinkfor10seconds.
ThenormalstateofthisLEDisoffformemberunitsandsteadygreenforthemanagerunit.
Adding a New Unit to an Existing Stack
Usethefollowingprocedureforinstallinganewunittoanexistingstackconfigura tion.This
procedureassumesthatthenewunitbeingaddedhasacleanconfigurationfrommanufacturing
andisrunningthesamefirmwareimageversionasotherunitsinthestack.
1. Ensurethatpowerisoffonthenew
unitbeinginstalled.
2. Useoneofthefollowingmethodstocompletestackcableconnections:
–Iftherunningstackusesadaisychaintopology,makethestackcableconnectionsfrom
thebottomofthestacktothenewunit(thatis,STACKDOWNportfromthebottomunit
oftherunningstackto
theSTACKUPportonthenewunit).
–Iftherunningstackusesaringstacktop ology,breaktheringandmakethestackcable
connectionstothenewunittoclosethering.
3. Applypowertothenewunit.
