As a project moves closer to reality. In some ways. Understanding the importance Installing Hardware of pre-installation planning. What is the purpose of a firewall server? What is the purpose of a server configured as a router? Explain the importance of a line conditioner?
Why should you consult a hardware compatibility list for your OS? How should servers be organized in a rack to prevent it from tipping? What hardware is needed to turn a server into a router? What is the difference between a RJ and RJ connector? Explain the importance of examining the components that have been delivered with a new server. What is the purpose of electrical grounding?
What factors should be taken into consideration when choosing net- work cabling? After the equipment has been delivered. Your servers need a home.
Some services have dependencies. If you do not currently have a DNS server. If your current server installa- tions do not meet the requirements of present and future needs. This chapter explains how to handle all these elements.
Before pur- chasing server equipment. In order to function properly. Installation planning Objective 1. Installation Strategy Before any server or network installation. Whether you are adding a server to an existing environment. An assessment of your current and future needs will aid you in this respect. They may be as simple as replacing an aging e-mail server. Depending on the type of service or function your server will perform. You may realize that one of your servers is currently run- ning under capacity.
You may find that with some minor upgrades.
Although you will not be using an exact replica of your new equipment. Depending on the type of appli- cation or service you are installing. Many of these types of server services can be combined in one machine.
A server that stores e-mail. The following are some of the most common kinds of servers: A file-and-print server provides file storage and printing services to clients.
For example. Exam Tip For the exam. This way. All of these planning concepts must be carefully balanced with the budget available to management. When client files are stored on the server.
The print requests are queued by the print server for delivery to the final destination printer. Print servers enable clients to send a request to a printer. Before executing your installation plan. A year from now. Combining several services onto one server can greatly reduce your costs. Some of these types of servers can also be performed by dedicated net- work devices. Test how each of your client and server operating systems will communicate with the new server services.
You will have to work within the constraints of certain spending limits. The e-mail system may be strictly internal. Types of servers Before you can plan your installation. Clients connect to the mail server by supplying their mail account information. A firewall acts as a security filter to separate and protect a private network from users of a public network. Combined with special faxing software. A proxy server forwards network requests on behalf of another client or server.
It facilitates these transfers with proper integrity. A client computer connects to an FTP server.
The proxy server can also cache Web data. These types of severs should have large amounts of RAM and disk space to be able to store and pro- cess the data. An application server is basically a server that acts as a middle tier in a multi-tiered application. A proxy server is typically configured to facilitate Internet Web page requests between a client and a Web server.
A backup server is used specifically for backing up system data. A Web server delivers Internet Web pages to client computers. If the data does not exist locally. The server receives that request. The backup server is usually attached to tape unit.
All network traffic flows through the firewall. A database server stores structured data in a filing system that can be retrieved by multiple users simultaneously.
If you are going to use a DMZ network. The client runs a Web browser. Figure shows an example of typical. Proxy servers are also useful for filtering requests. Firewall security is usually set up in three zones: Although a firewall can be a dedicated network device.
The server typically handles storage and process- ing of data. A domain name service DNS server keeps a database of tables that translate fully qualified Internet domain names to their respective IP address. This enables you to refer to Internet servers by name. The mail server and the Web server are in the DMZ.
When the client computer starts. With this configuration. A gateway server must be multihomed. Using a combination of hardware and software. With the gateway server in place. Each card will be connected to a different network.
An SNA server acts as a gateway between the client computer and the mainframe computer. The functions of a gateway server can also be performed by a dedicated network device.
Bridges are protocol-independent. A router can connect any number of Local Area Networks LANs by routing network packets to and from these different networks. Much like a router. Routing can also be performed by a dedicated network device. A router server must be multi- homed. Figure shows a server acting as a router.
All packets from LAN 1 on the left pass through the router. Figure shows an example of a bridge server connecting to different types of networks. A router con- tains a routing table. The OS CD will only con- tain information at the time of the initial release of the software.
Each type of hardware. To get the latest versions of the list. If the hardware is not supported by the operating system. Ensure that your electrical outlets in your server room are properly grounded. If updating the electri- cal system is not an option. This will increase the load on the UPS.
You can spend a lot of time and money on planning out a server. Make sure there are enough outlets to power your equipment. You can check this by examining the outlet to see if it contains a third grounding. This can cause permanent damage to your components. Caution Avoid plugging power strips into the UPS to create more sockets.
Grounding The primary purpose of electrical grounding is to protect equipment from short- circuiting. When the server is finally installed.
You should avoid having all your devices on the same electrical circuit. Location Before choosing a location for your server and rack. Quality If your server is located in an older building. Verifying the location of your power source. Before the servers are installed. Too many devices on one circuit could affect the consistency of the power flowing to the devices.
Some power outlets are color- coded to show which circuit an outlet is on. A ground refers to a path for the overloaded electrical current to dissi- pate. High deviations in the voltage and amperage could cause problems with modern.
It will usually keep them up for 10—20 minutes before the battery is depleted. You should also have an electrician test the power outlet.
There are many reasons for using a server rack to house your equipment: The equipment will not be subject to physical abuse and damage by being left out in the open. In the event of a power failure. Non-existent or improper grounding can cause great damage to your electrical equipment. With no type of power backup. When mounted in a proper rack. Uninterruptible power supply Another electrical consideration for a server room is the effect of a power outage.
A UPS will supply battery power to servers in the event of a power failure. AUPS is a must for any type of server installation. Even fewer test the auto Real World shutdown of the server feature. UPS systems come in a variety of sizes. Most UPS units come with special software that interacts with the operating system of the server.
The UPS uses a special signaling cable that is attached to the serial port of the server. They are typically measured using a VA rat- ing. In the Once a UPS is installed. If there is too much load on the UPS.
In the case of a real power failure. This gives you enough time to shut down the system properly. This allows the server to be shut down properly without any technician being on site. Exam Tip On the exam. Always imagine how you would perform the action in the real world using common sense. Several types of network topologies and cabling exist.
The choice of a topology will depend on your business needs. If for some reason the specifications are not present. A bus topology is most often used by coaxial Ethernet networks.
Network topologies Network topology refers to the actual shape of your local area network. Some racks also have their own fans. A disadvantage of a bus network is that if any device is dis- connected from the network.
Bus A bus network topology is one in which all of the devices are connected together in linear order by a central cable. See Figure for an example of bus network topology. Most racks have proper ventilation slots on the doors and sides to allow air to circulate. Racks are usually lockable. A standard rack height is approximately 42U.
It is perfect for small. When loading the rack. Each server or device being installed into the rack will have its own Unit measurement. Some small servers are only 1U in height. Remember to include any other devices. You must plan carefully how much rack space you have available for your servers. Rack space is measured in Units. A star topology network. A star topology also uses much more network cabling than a bus or ring topology.
Star topologies are most often used by twisted-pair Ethernet net- works. The real point of failure is with the central hub or computer. A bus topology network Star A star network topology is one in which the devices all radiate from a central hub.
If one of the network devices fails. See Figure for an example of a star topology network. If it fails. Coaxial cable consists of a stiff.
Each device is connected to the next device in the ring. Network information is passed along the ring until it reaches its destination computer. See Figure for an example of a ring topology network. Physical breaks in the ring cabling or a malfunctioning workstation can take down the entire network.
A ring topology network Types of cable Cabling your network depends on many factors. Coaxial Coaxial cable is one of the earliest types of network cabling. Because of its protective plastic. Token-ring networks use this type of topol- ogy. The purpose of the plastic is to prevent the cable from being bent so far that the copper conductor is broken.
Coaxial cable is much more expensive than twisted-pair solutions. A ring network is more expensive than a bus or start topology. The metal fiber is used to shield the wire from electromagnetic interference EMI. Each of the cable types discussed in the following sections have their own advantages and disadvantages depending on the type of your server and network installation.
Thicknet is a larger. For most modern network. Due to its cost. Twisted-pair Twisted pair wiring consists of pairs of wires that are twisted together. Twisted pair is used for phone networks and lower-end networks. There are two different types of twisted pair cabling: One wire carries the data.
Twisted-pair wiring is the most common network cabling used today. It uses RG cable. Thinnet cabling is usually used in place of Thicknet. This is the most common type of cabling today. It uses RG-8 or RG cabling. There are several standards for types of twisted pair cabling: This cabling is typically used for phone systems. Also referred to as Fast Ethernet. Thinnet coaxial cabling is a cabling standard for Ethernet LANs.
There are a number of different standards for twisted pair cabling: STP cable uses an extra casing around the wires to further prevent EMI from interrupting network communications. Also referred to as Gigabit Ethernet. Multimode fiber has a larger core width. BNC connectors are locked into place by a rotat- ing ring. This connector is used to connect eight-wire connections.
There are two types of fiber cabling. Connectors Each type of network cabling requires its own type of connectors and devices to work properly.
For bus networks. This connector is used for connecting four. The cable is actually pierced and direct contact is made to the core conducting wire. Fiber cable is split into two different wires. The AUI interface includes a transceiver that connects a coax- ial cable with a pin connector. On the connecting device there will be two connectors. It is usually referred to as two-pair wire.
It is usually used in conjunction with a transceiver and an AUI connector. A vampire tap is used to connect older Thicknet types of net- works.
A BNC barrel connector is used to connect two cables together. Companies will often build the backbone of their network. This provides much greater speeds and distances. Single mode fiber has a very narrow internal path that only permits one mode of light through at a time. An AUI is typically used on coaxial-based network cards.
A plastic covering protects the cable. The wires must go in the proper connectors. It is used for phone cabling. It is widely used for LAN Ethernet networks. Exam Tip Although networking is not the focus of the exam. Fiber-optic cable is extremely fast and reliable. Running them across the floor is a simple. The cables are protected from external damage. This is the best solution. Many professional server rooms have false floors. The conduit is usually made of a hard but bendable plastic.
For SCSI cables. For IDE systems. These are simply brackets that run around the upper perimeter of the room. The following are some things to consider when verifying your server components before installation. There are quite an array of different SCSI devices and cables. They should be located either under the floor. Be sure to check every component carefully.
Server racks typically come with holes in the top. An alternative to running cables right into the ceiling is through the use of cable trays. The cables are also covered and pro- tected from external damage. Running the cables along the floor leaves them susceptible to damage from people walking on them. Underneath is where most of the cabling is run. The importance of verifying hardware compatibility with the network OS was discussed. Check any additional peripheral cards that were delivered with your server for compatibility with your motherboard.
Keep the following points in mind for the exam: You should examine the NIC cards to make sure they are the proper model for your network installation. Check that the connectors on the edge of the network card are compatible with your network topology and cabling. Ensure there are enough slots to connect all of the cards.
