Chapter 1 Control and Indicators • Keyboard - This port accepts a standard keyboard with a PS/2 connector. • LAN -This port is an embedded controller that has an RJ-45 LAN connector. • USB - This port is provided for printers, scanners, and external modems. • Serial A - This is a standard serial port connector. • Serial B - This is a standard serial port connector. • Parallel - This is the standard parallel printer port connection. • Mouse - This connector accepts a standard PS/2 mouse. • Video SVGA - This connector provides the video signal to drive the Server's monitor. Refer to "Video Display Modes" on page 122. NIC Indicators The embedded NIC (Network Interface Card) has two LEDs associated with it, which can only be seen from the rear of the HP Server tc4100. See Table 1-6. Table 1-6. NIC LED Code Indicator Link/Activity LED 10/100 Mbps LED Definition This LED turns solid green to indicate that it is linked and properly connected. The green LED blinks to indicate the embedded NIC (network adapter) is active and transferring data to/from the NIC. The rate of blinking varies directly with network traffic. This yellow LED turns on to indicate when the NIC is supporting transfers of 100 Mbps (million bits per second). When it is off, the NIC is supporting transfers of 10 Mbps. Applying Power to the HP Server tc4100 Powering Up the HP Server tc4100 1. Ensure that the HP Server tc4100's power cord or power cords are connected to the power source. See Figure 1-8. 2. Press the Power button on the front control panel. See Figure 1-5. NOTE Each time AC power is applied (power cord is plugged in), there is a 15 second delay (self test) before the front control panel will respond to your actions. Powering Down the HP Server tc4100 1. Log off all users and, if necessary, back-up files. Follow instructions in your network operating system (NOS) documentation to gracefully shut down all networking software and applications. 2. Press the power switch on the HP Server tc4100 control panel when prompted by the operating system. 3. Normally, this completes the shutdown procedure. NOTE The power supply will continue to provide standby voltage to the HP Server tc4100 until the power cord(s) is/are disconnected. 14
