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 located
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, standby, or
member unit). For more information about C1048P LED behavior, see
System LEDs .

4. Main AC power supply connector: The C1048P PE has an internal 1000-
watt power supply that feeds up to 24 PoE devices at full PoE+ power
(850W). PoE power is dynamically allocated.
NOTE: The AC power connector on a C1048P requires an
IEC-320-C15 power cable, which is different than the C13 power
cable used on most lower wattage switches.
5. External DC power supply connector: You can connect an additional
external power supply (MPS1000) to provide 1000 watts and full power
coverage for all 48 PoE devices (1800W).
6. Fan vents: Two fans are used to cool a C1048P PE.
