Redundant Pairs
ARX®1000 Hardware Installation Guide 2-3
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.
Redundant Pairs
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 CLI Network-Management Guide and CLI Reference Guide 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.
