Power Supply
The AC/DC power supply provides the following features and functions:
• Provides 450 Watts @ +2.5 V, +3.3 V, and +12.0 V for switch operations. (Note
that the power supply draws up to 608W from the AC power cord due to its
operating efficiency.)
• Uses remote sensing to maintain stable voltage and to account for any DC loss in
cabling.
• Provides an AC alarm to indicate when power is about to be removed from the
system. When this alarm is activated, the power supply maintains full regulated
load for a minimum of 20 milliseconds, enabling the system to shut down power
gracefully.
Internal Disks
The switch uses internal disk drives to store its software image, configuration files,
log files, and other maintenance-related data. The ARX®1000 contains two
redundant SATA drives, configured RAID1. These drives are connected to the
primary controller on the Application Control Module (ACM). They are
Field-Replaceable Units (FRUs); procedures to swap a drive appear in a later chapter.
IDE Hard Drive
Older versions of the ARX®1000 hardware contain a single, non-replaceable hard
disk. The disk is an Integrated Drive Electronics (IDE) drive.
Fan Unit
The internal fans are an environmentally-controlled cooling system. The ACM is
connected to the fan unit for temperature control and status monitoring at 60-second
intervals.
