Hardware Features
Redundant Pairs
2 - 4
The ARX®1000 switch provides or supports the following hardware
features:
• 2U compact design
• Box-to-box failover capability (for redundant ARX®1000 switches; see
the next section)
• External interfaces including:
• serial console port
• out of band 10/100Mbps Ethernet management port
• two Gigabit Ethernet Small Form Factor Pluggable (SFP) ports (with
SX fiber optics)
• four 100/1000BASE-T Ethernet ports
• Front panel LEDs to indicate system status, port link status, and
NVRAM battery status (shown in Figure 7.3 on page 7-5)
• Auto-sensing (110-220V) power supply
• 2 80GB internal Serial ATA (SATA) hard disks
These are configured as a RAID1 (a redundant, mirrored array of disks).
Either disk is hot-swappable.
You can purchase two ARX®1000 switches and configure them as a
redundant pair. If the primary switch fails, all services "fail over" to the
secondary switch. This is a highly-available configuration.
The redundant switches are interconnected through one or more of their
Gigabit Ethernet ports. You use the CLI to configure the ports for
redundant-link traffic (as opposed to client/server traffic).
See the ARX CLI Network-Management Guide and ARX CLI Reference for
information about configuring redundant switches.
If you are installing the second switch in a redundant pair, there are
differences in the initial-boot procedure. The differences are outlined later in
Chapter 6, Connecting the Switch to the Network.
