Reverting the Access Port to Uplink Port
You can revert the configured access port back to uplink port.
Use no stack-unit unit-number access-ports port-range command to revert the access port back to uplink port.
After executing the above command, following message appears:
Dell(conf-pe-2)#no stack-unit 1 access-ports 1
Dell(conf-pe-2)#Oct 16 06:37:04 %RPM1-P:CP %IFMGR-5-ACCESSPORT_DELETED: PEX port(peTenGigE
2/1/49) has been converted to an uplink port
Locating the Port Extender
• Use the location-led command to locate a PE by toggling its LED off and on.
EXEC Privilege mode
location-led pe pe-id stack-unit unit-number
The following example turns on the green blinking light on the main PSU LED on port extender 0 stack unit 5.
Dell#location-led pe 0 stack-unit 5 on
The following example disables the location-led feature on the PE stack-unit 5
Dell#location-led pe 0 stack-unit 5 off
Troubleshooting a PE Stack
To troubleshoot the operation of a PE stack, use the following tasks.
Diagnosing an Error Condition
For debugging purposes, you can prevent the stack master from rebooting after a failover to allow you to gather information on stack
operation.
CONFIGURATION mode
redundancy disable-auto-reboot pe pe-id stack-unit unit-number
• pe-id — port-extender identifier of the master unit. The range is 0 through 255.
Dell(conf)# redundancy disable-auto-reboot pe 2 stack-unit unit-number
NOTE:
The redundancy disable-auto-reboot pe command does not affect a forced failover, manual reset, or a
stack-link disconnect.
