Network Management Tools
Console management port Each model has one RS-232 port that accepts a
DB-9 (female) connector for direct CLI access from a console terminal.
USB port Each model has two ports that can be used for memory storage
devices.
Ethernet interfaces Each model has two 10/100/1000Base-T Ethernet ports
(ETH0 and ETH1) that accept an RJ-45 (male) connector, providing an out-of-band
connection for LAN access through a Telnet session, SSH, or SNMP. ETH0 provides
access from a network that is behind a firewall. ETH1 provides access for
applications on an external network, such as the Internet.
Generic interfaces Each model has two generic ports (ETH2 and ETH3) that
enable you to use standard connectors, such as small form-factor pluggable
transceivers (SFPs), to create fiber-optic or Gigabit Ethernet connections and
provide additional LAN connectivity. The following SFPs are available:
1000Base-SX Duplex LC connector, multimode, rated for 500 m over
10–micron core cable, 850-nm laser transmitter
1000Base-LX Duplex LC connector, single-mode, rated for 10 m over
10–micron core cable, 1310-nm laser transmitter
1000Base-T RJ-45 connector, rated for up to 100 m on CAT5 cable
Status LEDs Each model has LEDs that provide information about hard drive,
power supply, and interface status.
USB storage device Contains the latest system software, including the operating
system for the C Series Controller. The device is read-only and should be used
to recover from a major software failure. See the SRC Release Notes for more
information about recovering from a software failure.
