Chapter 1: Controls, Ports, and Indicators
Applying Power to the HP Server
Before applying power to the HP Server, verify that the keyboard and mouse are connected to the
proper ports. The server will not boot without these devices. Turning on the monitor prior to
powering on the HP Server allows proper auto-configuration of the video output as it boots.
Powering-Up the HP Server
To power-up the rx4610, complete the following procedure:
NOTE Turn on power to the monitor connected to the HP Server before you power-on the
Server. This allows proper
auto-configuration of video output of the Server as it boots.
1. Make sure that the monitor, keyboard, and mouse have been connected to the proper ports on
the rear panel of the server.
2. Remove the drive protection card, if present, from the diskette drive.
3. Plug in the power cord for the monitor and turn it on.
4. Plug the female ends of the server AC power cords into the input receptacle on the back of the
chassis.
5. Plug the male ends of the server AC power cords into grounded,
three-pronged AC power outlet.
6. Slide the server into the rack.
7. If the server does not come on when you plug it into the AC outlet, press the on/off power
switch on the front panel.
8. Verify that the power-on light on the front panel is lit. After a few seconds, the power-on self
test (POST) begins.
When you press the power button on the control panel, the Server powers up and loads the
operating system. The system runs a set of power on self tests (POST) during this process. For
details refer to Chapter 11, "Troubleshooting."
Powering-Down the HP Server
To power-down the HP Server, complete the following procedure:
1. Log off all users and, if necessary, back up the system files.
◊ Schedule the power down for a time when the Server being down will affect the fewest
users.
◊ If you will be doing any kind of hardware or software upgrade, ensure the Server's data has
been backed up.
◊ Follow instructions in your network operating system (NOS) documentation to gracefully
shut down all networking software and applications.
WARNING The power supply will continue to provide standby current to the HP Server until
the power cable is disconnected from the rear panel.
10
Chapter 1: Controls, Ports, and Indicators
2. Logoff and exit the operating system. The following prompt appears:
Shell>
3. At the Shell> prompt, press and hold the Power button for several seconds. Holding the Power
button in for several seconds will power down the server.
4. Disconnect the power cords from the power source.
Normally this completes the power-down procedure.
Connecting AC Power to Multiple-Server Configurations
The HP Server temporarily draws a large "inrush current," when first connected to an AC power
source. This also occurs when the Server 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 Server's normal operating
current and generally, the AC power source can handle the normal inrush current.
However, if you install several HP Servers on one circuit, precautions are necessary. If there is a
power failure and power is then restored, all the servers immediately begin to draw inrush current at
the same time. If the circuit breakers on the incoming power line have insufficient capability, the
breaker may trip and thus prevent the servers from powering up.

The two 120 mm cooling fans are mounted on the top front of the chassis. These fans can be replaced
without shutting down power to the system. If it is a failed fan, the amber LED will be illuminated on
the front panel, and the amber LED on the failed fan itself will be illuminated. The individual fan
LEDs may be seen through view-ports in the fan covers
Removing the 120 mm Fans
To remove the 120mm fan, complete the following procedure:
1. Slide the server out of the rack far enough to expose the fan-access door on the top of the
chassis.
2. Unscrew the thumbscrew on the front of the fan-access door and lift the door open. If a fan
has failed, the amber LED light is illuminated.
CAUTION Do not leave the door open for an extended time. Cooling of the system could be
reduced
3. Grasp the fan assembly through the finger holes and pull the assembly out.

Hot Swapping Power Supplies
The power system contains four 800-watt autoranging power supplies. The third bay’s power supply
from the left as you face the chassis serves a redundancy function for the server’s power supply
requirements.
CAUTION Because of chassis airflow disruption, the power supply bay should not be vacant
for more than five minutes when server power is on. Exceeding the five-minute
limit might cause system cooling to fall below the minimum required level and
possibly cause damage to system components.
NOTE The server requires a minimum of three power supplies to operate. If you have
only three power supplies operational, they must occupy the first, second, and
fourth power supply bays as you face the chassis. Figure 3-3 shows the power
supply installation order.

If only 3 power supplies
are operational, place a
filler panel over the fourth
bay in the installation order.

Determining Power Supply Status
When the amber power supply failure LED on the front of the chassis turns on, determine which
power supply is defective by checking the three status LEDs on each supply. Each power supply has
three LEDs that both indicate whether power is supplied to the power supply and the health of the
power supply. The LEDs are ordered top to bottom on each power supply. Table 3-1 illustrates the
states indicated by the three LEDs.

Removing a Power Supply
To remove a power supply, complete the following procedure:
1. Locate the power supply you want to remove.
2. Push the thumb latch to unlock the power supply handle and pull the handle down to undock
the supply.
CAUTION Any unused power supply slots must be covered with a blanking plug. Uncovered
slots can disrupt the air flow used for cooling the system.
