Chapter 1 Controls, Ports and Indicators Applying Power to the Appliance Powering-Up the Appliance 1. Ensure that the HP Cache Server Appliance's power cord and network cables are connected prior to powering on the appliance. 2. Press the Power push-button on the front control panel. When you press the power button on the control panel, the appliance powers up and loads the operating system. The system runs a set of power on self-tests (POST) during this process.
Chapter 1 Controls, Ports and Indicators Connecting AC Power to Multiple-Server Configurations The HP Cache Server Appliance temporarily draws a large "inrush current" when first connected to an AC power source. This also occurs when the appliance is in a standby mode (power is turned off, but the power cord is plugged into AC power). The inrush current is much greater than the appliance's normal operating current. The AC power source can handle the inrush current under normal circumstances.
2 Rack Mounting The HP Cache Server Appliance can be rack mounted in a variety of 2 and 4 post racking configurations. The appliances are shipped with the rails needed for 4 post racking configurations already installed. NOTE Read the complete racking instructions in the HP Cache Server Appliance sa2100/sa2150 and sa2200/sa2250 Rack Mounting Supplements on your documentation CD-ROM before attempting to rack mount these appliances.
3 Configuring the Cache Appliance This chapter describes the initial configuration process required to install the cache appliance on the network. Overview The following is an overview of the configuration steps: 1. Configure initial network parameters for LAN A of the appliance a. through DHCP/bootp - OR b. via a VT100 serial console session 2. Accept the settings thereby starting the Traffic Server application. 3. Additional network parameters can be configured through a telnet or VT100 serial session.
Chapter 3 Configuring the Cache Appliance Configuring Initial Network Parameters for LAN A If the appliance has received an IP address through bootp or DHCP and you know the IP address, you may use telnet to access the initial configuration session. (The MAC address is printed on a label on the right side of the appliance as viewed from the front or on the RJ45 connector.) 1. Telnet to the appliance IP address and use hpsaconfig for the user name and hpsa for the password. 2.
Chapter 3 Configuring the Cache Appliance Upon successful completion of the initial configuration, the appliance will start and configure the Traffic Server software to run with the network settings just entered. NOTE After the initial configurations are saved, the network parameters will be saved as a static configuration on the appliance. This is true even if the appliance received the initial IP configuration via bootp or DHCP.
Chapter 3 Configuring the Cache Appliance Monitoring Traffic Server Once Traffic Server is up and running, you can monitor and modify its operation from the Traffic Manager Dashboard. The Dashboard is shown in Figure 3-1. Access Traffic Manager by directing your browser to: http://:8081 where 8081 is the default traffic manager port. The HP Cache Server Appliance Administrator Guide describes how to use Traffic Manager. Figure 3-1.
