The C2000 model and C4000 model contain the following components:
Hard drive—Each model has two hot-swappable, redundant
drives in a redundant array of independent disks (RAID) 1 (mirror)
configuration. The C2000 model has two hard drives located in the
front, and the C4000 model has two hard drives located in the rear.
Fans—The C2000 model has two hot-swappable fans
located in the rear. The C4000 model has two hot-swappable fan trays
located in the rear. Each fan tray contains three fans.
Power supply—Each model has two hot-swappable, redundant
AC-power supplies located in the rear. Depending on the model, each
power supply module has either two (C2000 model) or one (C4000 model)

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
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.
