2E4X-27R Overview
2E48-27R/2E49-27R User’s Guide 1-3
Figure 1-1 The 2E48-27R and 2E49-27R
The 2E4X-27R is a tabletop unit that can be installed in a standard
19-inch rack using the supplied rack mounting hardware.
The 2E4X-27R has two power supplies. The power supplies load share
50% (+/-5%) of the power required by the device. If one power supply
fails, the remaining power supply assumes the entire load of the device
without interruption to network traffic. Each power supply module
supports its own ac input connection, which allows the user to connect
each power supply to a different ac power circuit.
