PC7048
PowerConnect 7048 switches have an internal 180-watt power supply.
The additional external power supply (PowerConnect RPS720) provides
180 watts and gives full redundancy for the switch.
PC7048P
PowerConnect 7048P switches have an internal 1000-watt power supply
which can support up to 24 ports of PoE. The additional external power
supply (PowerConnect MPS1000) allows all 48 ports of PoE, or 24 ports of
PoE and full redundancy for the switch.
PC7048R and PC7048R-RA
PowerConnect 7048R and PowerConnect 7048R-RA switches are designed as
top-of-rack switches and include two internal, replaceable, AC power supplies
for redundant or load-sharing operation. Each power supply can provide
300 watts and includes hot-swap support. This means you do not need to
power-down the switch to remove or replace one power supply while the other
power supply is operating normally. However, it is necessary to remove power
from the power supply that is being removed or replaced.
CAUTION:
Remove the power cable from the modules prior to removing the
module itself. Power must not be connected prior to insertion in the chassis.

Ventilation System

Three fans cool the PowerConnect 7024, PowerConnect 7024F, and
PowerConnect 7048. The PowerConnect 7024P and PowerConnect 7048P
each have two fans, with a third fan in the internal power supply.
The PowerConnect 7048R has two hot-swappable fan trays with one fan each.

Locator LED

The back panel includes an LED to help identify the switch within a rack or
room full of switches. From your remote management system, you can set the
LED to blink to help you or a local technician identify the physical location of
the switch.
