C-series Model Components
The C2000 model and C4000 model contain the following components:
- Internal memory
- 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) associated

- Console management port—Each model has one RS-232 port
that accepts a DB-9 (female) connector for direct CLI access from a console
port—Each model has two ports that can be used for memory storage devices.
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.
- Status LEDs—Each model has LEDs that provide information
about hard drive, power supply, and interface status.
storage device—Contains the latest system software, including the operating
system for the C-series platform. 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.
- Rack-mount and rail kit.
