Redundancy Features
The ARX
®
6000 system is designed to provide a highly available service
with fault tolerance and no single point of failure. This design provides the
following features:
• High availability (HA) clustering for switch redundancy, including
intra-box (modules) and inter-box (redundant-pair) failover capability:
• For multiple NSMs in a single chassis, if a one fails the other provides
connectivity for all other modules.
• 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.
See Chapter 3,
Chassis Hardware, for more information about these chassis
components.
Switch Management
For local and remote management, the ARX
®
6000 provides the following
management interfaces:
• one serial-console port (labeled “Console”),
• one out-of-band 10/100 Ethernet port (labeled “MGMT”), and
• a configurable number of inband Ethernet interfaces.
See Chapter 7,
Connecting the Switch to the Network, for information about
bringing the out-of-band MGMT port online after initial boot-up.
See the ARX® CLI Network-Management Guide
and ARX® CLI Reference
for information about configuring the in-band interfaces.
