C1048P Back Panel The back panel of the C1048P PE is shown in the following illustration and described below. Figure 3. C1048P Back Panel 1. Stack ports: Each C1048P has two fixed mini-SAS (STD) stacking connectors on its back panel. Stack port 1 is on top; stack port 2 is on the bottom. You can stack up to eight C1048P PEs using the mini-SAS ports on the back panel. A C1048P PE supports stacking only with other C1048P PEs. When you connect multiple C1048P PEs using the stack ports, the PEs operate as a single unit with up to 384 front panel ports. The stack operates and is managed from a C9010 switch as a single entity. In a C1048P stack, the Stack Master/Member LED on the front panel indicates operational status (standalone, stack master, or member unit).

Stack ports: Each C1048P has two fixed mini-SAS (STD) stacking connectors on its back panel. Stack
port 1 is on top; stack port 2 is on the bottom.
You can stack up to eight C1048P PEs using the mini-SAS ports on the back panel. A C1048P PE
supports stacking only with other C1048P PEs. When you connect multiple C1048P PEs using the
stack ports, the PEs operate as a single unit with up to 384 front panel ports. The stack operates and
is managed from a C9010 switch as a single entity.
In a C1048P stack, the Stack Master/Member LED on the front panel indicates operational status
(standalone, stack master, or member unit). For more information about C1048P LED behavior, see
