C-series Model Components

The C2000 model and C4000 model contain the following components:

• Internal memory
• CPU
• 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 fan.

• 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.
• 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 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.
