2.3 MX48 Modules
The inspired modular approach of the MX48 allows for all critical system components including power
supplies, cooling fans and pluggable optics (SFP+) to be hot-swappable, thus minimizing business
impact in the unlikely event that a component should fail.

Power Supplies
One power supply is standard with the MX48 Chassis. However, an optional dual, redundant power
supply is available to ensure continuous, uninterrupted power. The supplies are current sharing, which
means the supplies share the load equally. If a power supply were to fail, the single power supply can
handle the entire current load of the MX48 system. Although the router functions properly with one
Power Module, it is recommended that, for redundancy, both Modules be connected to two independent
power sources. Additionally, the hot-swappable feature allows for easy replacement of a module without
interrupting the router
’s system functionality.
Fan Tray
The MX48 uses 3 DC fans all located conveniently in one modular fan tray. The tray is designed to move
air horizontally through the enclosure. This hot-swappable fan tray allows for easy replacement of the
module (in case of failure) without interrupting the system functionality. Any 2 DC fans will adequately
cool either system.
The Fan Tray is also equipped with an Annunciator Port for the use of alarms. The system alarms can be
configured to trigger an external control system or generate email notifications.
