Dell S4820T, Configuration Manual

Management Access on S-Series Stacks
You can access the stack via the console port or VTY line.
• Console access — You may access the stack through the console port of the master unit (stack
manager) only. Similar to a standby RPM, the console port of the standby unit does not provide
management capability; only a limited number of commands are available. Member units provide a
limited set of commands.
• Remote access — You may access the master unit and standby unit in a stack through the dedicated
management Ethernet interfaces with SNMP, SSH, or via Telnet.

You can connect two units with two or more stacking cables in case of a stacking port or cable failure.
Removal of only one of the cables does not trigger a reset.
Important Points to Remember
• You may stack up to six S4820T systems.
• The S4820T cannot be stacked with other system types.
• You cannot enable stacking and virtual link trunking (VLT) simultaneously on the device. To convert a
stacked unit to VLT, refer to Reconfiguring Stacked Switches as VLT .
• Data ports are configured as stacking ports in predefined groups of four 10G ports called stack-
groups. When using the 40G ports, you can configure a single port as a stack port; each 40G port is a
stack-group.
