Installing the Hub in a Rack Attaching the Hub to the Rack After the brackets are attached, use two of the Phillips machine screws to securely attach each bracket to the rack, as shown in Figure 2-4.
Attaching the Cable Guide to the Bracket Attaching the Cable Guide to the Bracket Attaching the cable guide and securing the cables in the cable guide prevent the cables from obscuring the hub and other devices in the rack. If the hub is in a 19- or 24-inch rack, you can attach the cable guide to the left or right rack-mount bracket with the black screw, as shown in Figure 2-5.
Installing the Hub on a Wall Installing the Hub on a Wall This section describes how to attach the hub in parallel and vertically to a wall. Note Be sure the hub is powered off and is not connected to a power source before you perform the steps in the sections that follow.
Attaching the Hub to a Wall Attaching the Hub to a Wall For the best support of the hub and cables, make sure the hub is securely attached to a wall stud or to a firmly attached plywood mounting backboard, as shown in Figure 2-7. You must supply your own screws to attach the hub to the wall. Note If you plan to use the optional switched uplink module, install it in the hub before vertically attaching the hub to a wall.
Connecting to the Console Port (FastHub 400M Models) Connecting to the Console Port (FastHub 400M Models) To connect the RJ-45 console port of a FastHub 400M model to a management station or modem, you must use the supplied RJ-45-to-RJ-45 rollover console cable and the appropriate adapter and follow these steps. Note The rollover console cable and a RJ-45-to-DB-9 female DTE adapter are supplied with the hub.
Connecting to the Console Port (FastHub 400M Models) Step 2 Connect one end of the supplied rollover console cable to the console port, as shown in Figure 2-8. Do not connect an actual telephone line, an ISDN line, or an Ethernet cable to this console port. Damage to the hub can result. Make sure you use the supplied RJ-45-to-RJ-45 rollover cable and adapters to connect the console port to the management station or modem.
Assigning IP Information to the Hub (FastHub 400M Models) Assigning IP Information to the Hub (FastHub 400M Models) After you install the hub and connect it to a management station, you can assign IP information to the hub. IP information identifies the hub to the network and is required to manage and monitor the hub through the FastHub 400 series Hub Manager, the CLI, or SNMP.
Assigning IP Information to the Hub (FastHub 400M Models) Step 5 Enter the IP address of the default gateway (for example: 10.1.105.254): Enter IP default gateway: 10.1.105.254 Note If the management station from which the FastHub 400 series Hub Manager is used is not on the same IP subnet as the hub, you must also assign a default gateway (the router for the local subnet). The following information is displayed: The following configuration command script was created: ip address 10.1.105.20 255.255.
Connecting to the 10/100 Network Ports and Uplink Port Connecting to the 10/100 Network Ports and Uplink Port You can connect the 10/100 network ports and the uplink port to the ports on any 10BaseT or 100BaseTX network device, such as workstations, servers, switches, routers, and other hubs. The 10/100 network ports (ports 1x through 12x or 1x through 24x) are internally crossed.
Connecting to the 10/100 Network Ports and Uplink Port • Connecting to devices that do not autonegotiate or that have their speed setting manually set can reduce performance or result in no link. To maximize performance, choose one of these methods for configuring the 10/100 ports: — Let both ports autonegotiate port speed. — Manually set the same speed setting for the ports on both ends of the connection.
Accessing the Management Interfaces (FastHub 400M Models) Step 2 Connect the other end of the cable to the 10BaseT or 100BaseTX port of the network device. Step 3 Check to see that the port LED for the port that you connected in Step 1 comes on. If the port LED does not come on, check for the following problems: • • • • The network device is not turned on. The Ethernet adapter in the network device is not operating correctly. You are using the wrong type of Ethernet cable.
Accessing the FastHub 400 Series Hub Manager Accessing the FastHub 400 Series Hub Manager To access the hub manager, all you need is the IP information of the hub (and the password if one has been assigned). IP information for the hub is usually assigned when the hub is first started up after installation. (See the “Assigning IP Information to the Hub (FastHub 400M Models)” section on page 2-16.) Note You can access the hub manager from a PC connected to one of the 10/100 ports.
