Front and Rear Panel Components Table 1-3 describes the various components illustrated in Figure 1-3. Table 1-3 Front Panel Components Component Description Disk drives These removable hard drives can be placed in drive carriers and can be hot-swappable. The drive carriers are connected to the system internally via a custom backplane that interfaces with a RAID storage card. Specifics of the RAID card used depend on the system specifications of your order.
1: Overview Table 1-3 Front Panel Components (continued) Component Description LED indicator lights These LEDs provide you with critical information related to different parts of the system. Green (PWR): The LED farthest to the left indicates that power is applied to the server and the system is on. When the LED is off, the system is off, even if the AC power cord is plugged into the server.
Front and Rear Panel Components Table 1-3 Front Panel Components (continued) Component Description Rear fans Keep the area behind the fans clear and unobstructed. This will ensure proper airflow to the components inside the server chassis. Serial connector This port is accessed with an RJ-45 connector. When the Roamer remote management module is installed, this port functions as an interface to the module.
Chapter 2 2. Pre-Installation Guidelines To ensure safe and efficient operation of your server, proper planning is essential. Factors such as the proper location of the server in its rack, adequate power to the components in the rack, and the appropriate operating environment for the rack.
2: Pre-Installation Guidelines • If you are installing multiple servers or other components in the rack, place the components and servers in positions that they can be easily opened and serviced. For example, the heaviest components—such as a uninterruptible power supply—are placed at the bottom of the rack; servers are often in the middle of the rack.
Rack Stability Rack Stability The rack must be strong enough to hold the installed components. • Ensure that the leveling jacks at the bottom of the rack are fully extended and are secure. • If using a two-post (telco) rack, be sure that the rack is securely fastened to the building at the top and the bottom. • In single rack installations, stabilizers should be attached to the rack. • When working with components in the rack, never slide out more than one unit at a time.
Chapter 3 3. Installation Guidelines This chapter describes how to install your server into the rack. Warning: Your server is designed for rack mounting. It is not designed for use as a desktop system. Do not place a monitor on the server or place anything on top of the enclosure. Additional weight on top of the server could cause damage to internal components.
3: Installation Guidelines Getting Ready to Install You can install the server into any four-post rack or two-post (Telco) rack. Preparations for installing are the same regardless of what type of rack you using for the server. Important: Check the documentation for your rack for any special instructions or requirements. Before beginning work with the server and rack, make the following preparations: • If possible, arrange to work with another person for safety.
Installing into a Rack or Cabinet Installing into a Rack or Cabinet A rack can be either open or enclosed in a cabinet. Follow the same instructions to attach the server to either type of rack. For a cabinet, it helps to remove the door before installing the server. The server does not require conventional rack or server rails to be installed. The server is designed to slide easily between the mounting rails of the rack.
3: Installation Guidelines Cabling Once the server is secured in the rack, you can connect the Ethernet cables and power cord directly to its front and back panels, respectively. Before connecting them, do the following: 1. Gather the cables you will connect to the server. 2. Make certain each cable has the proper connector and that it is designed for use in a high-capacity server. 3. Label each cable so that you can locate a specific cable quickly. Ethernet ports on the server are numbered 0 and 1.
Installing a Hard Drive into the Hard Drive Carrier Installing a Hard Drive into the Hard Drive Carrier To install a hard drive into the hard drive carrier, perform the following steps after removing the hard drive from the chassis: 1. Place the hard drive carrier on a flat, stable surface such as a desk, table, or work bench. 2. Slide the hard drive into the carrier with the printed circuit board side facing down (see Figure 3-1). 3. Carefully align the mounting holes in the hard drive and the carrier.
Chapter 4 4. Using the Server This chapter describes basic server operation, how to turn the server on and off, and how to use Roamer remote management. Powering the Server On After the server chassis is connected to AC power, the server can be turned on in any of the following ways: • Press the power-control button on the front of the server. While the server is powering up, the power LED on the front of the chassis is lit.
4: Using the Server Powering the Server Off When the server is turned off, it remains connected to AC power through the server chassis. The server can respond to requests to turn on remotely or locally through Roamer. To remove all power from the server, power must be disconnected from the server chassis. Shut down your operating system before turning off the server. Refer to the operating system documentation in reference to proper operating system shutdown.
Working with Roamer Remote Management Working with Roamer Remote Management If the server you purchased has the optional Roamer remote management hardware present, then the server can be managed remotely using this option. The Roamer option provides standard motherboards with enhanced remote control and serial redirection capabilities. The Roamer is accessed locally using an RJ-45 serial connection (shown in Figure 4-1). With the Roamer option comes a LCD display.
Appendix 5 E. Safety Guidelines The safety guidelines categorized as follows: • “Electrical Safety” on page 27 • “General Safety” on page 28 • “Handling Your Server” on page 29 Electrical Safety Observe the following basic electrical safety precautions to protect yourself from harm and the server from damage: 007-5717-001 • Be aware of the locations of the power on/off switch on the chassis as well as the room's emergency power-off switch, disconnection switch, or electrical outlet.
5: Safety Guidelines • The power supply power cords must include a grounding plug and must be plugged into grounded electrical outlets. • Verify that the electrical outlets and power strips used by the server have reliable earthing. • Verify that the server is plugged into an electrical outlet with appropriate circuit overloading protection. General Safety The following are general safety guidelines: • Keep the area around the server clean and free of clutter.
Handling Your Server Handling Your Server When handling the server, use the following guidelines: 007-5717-001 • When the server is removed from the rack, set it on a sturdy and flat surface. Do not set any heavy objects on top of the server. Any additional weight could possibly damage essential internal components. • When connecting or disconnecting a cable, always hold the cable by its connector. • Never force a connector into a port.

Appendix B B. RAID Basics To assist you in building RAID arrays, this chapter gives a general overview of RAID and describes various levels of RAID along with JBOD. RAID Implementations RAID can be implemented in either dedicated hardware or software running on standard hardware. Occasionally, you might want hybrid RAID systems—combining software- and hardware-based solutions. With software implementations of RAID, the operating system manages the disks through the normal drive controller (SAS/ SATA).
B: RAID Basics RAID 0 (Striping) RAID 0 (also known as a stripe set) splits data evenly across two or more disks with no parity information for redundancy. RAID 0 is not redundant. RAID 0 is used to increase performance, and can be used as a way to create a small number of large virtual disks out of a large number of small physical ones. RAID 0 can be created with disks of differing sizes, but the storage that is added to the array by each disk is limited to the size of the smallest disk.
RAID 5 (Parity) RAID 1 has administrative advantages: it allows 24/7 environments to do backups on the array. Mirroring is useful when critical data needs to be stored and backed up. RAID 5 (Parity) A RAID 5 array uses block-level striping with parity data distributed across all the member disks. RAID 5 is the most popular RAID level and is used in both hardware and software RAID.
B: RAID Basics RAID 10 (Mirrored Stripes) RAID 10 is a combination of RAID 1 and RAID 0. RAID 10 is a stripe across a number of mirrored sets. It combines the best features of striping and mirroring to yield large arrays with high performance in most uses and superior fault tolerance. RAID 50 (Striping with Parity) RAID 50 employs RAID 0 striping across lower-level RAID 5 arrays. One disk in each sub-array can fail without a loss of data.
