Product Overview

Hardware Features
The ARX supports the following hardware features:
• 4U compact design (2U control plane,
2U data plane).
• Box-to-box failover capability (for redundant ARXs). For details on
failover, see Redundant Pairs , on page 2-4.
• Single bezel covering for control and data plane components.
• 4 AC power cords (15 amp, 110 volt).
• PCI-E interconnect cable (control plane to data plane).
• External interfaces including:
– Serial console port
– 10/100/1000 Mbps out-of-band (OOB) Ethernet management port
– 12 copper 100/1000 gigabit Ethernet ports
– 2 optical 10 gigabit Ethernet ports
• Front control panel LEDs that indicate port activity, disk drive activity,
system status, and power.
• Front data panel LEDs that indicate PCI link status (connected, valid),
NVRAM battery status, power supply status, and various operational
states.
• 4 power supplies with the following characteristics: 1:1 redundant,
load-sharing, universal, auto-sensing, hot-swappable (110 volts and 220
volts).
• 2 146 GB internal SAS hard disks, configured as a RAID1 (redundant,
mirrored array of disks). Either disk is hot-swappable.
Redundant Pairs
You can purchase two ARXs and configure them as a redundant pair. You
connect the pair through one or more of their gigabit Ethernet ports. You
then use the CLI to configure the ports for redundant-link traffic (as opposed
to client/server traffic). This provides a highly-available (HA) service with
fault tolerance and no single point of failure.
This redundant design provides the following features:
• For two switches in a redundant pair, one switch starts as primary and the
other switch starts as secondary . If a module in the primary switch fails,
the switch “fails over” to the secondary switch.
• Redundant Array of Independent Disks (RAID) Level 1 protected
boot/configuration disk drives.
• Redundant power supplies installed share the power load.
• Redundant connections to the fan tray.
• Redundant AC/DC power.
