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). 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 the C1048P PE.
