5. If you use hook-and-loop straps, tighten each of them to ensure they
support the cables correctly. Slide the NetServer in carefully making sure
cables do not bind, adjust cables and straps as necessary. Repeat until the
Cable Management Arm extends and retracts smoothly.
6. Secure the server to the front of the rack with screws and rack nuts and
replace the bezel. See the HP NetServer LH 6000/6000r Installation Guide
for details.
Step 5: Powering Up and Powering Down the
Components in the Rack
Follow the Power Up Sequence to minimize inrush currents and prevent breakers
from tripping.
Power Up Sequence
1. Power on peripherals one at a time, beginning with the tape back-up unit,
continuing with the mass storage units, monitor, and the rest.
2. If an HP Console Switch is present, it must be on before the server is
powered on. Otherwise the server will not detect all the required
components and will likely report an error.
3. Lastly, power on one server at a time, waiting for fan units in one to spin
up before powering on the next (if more than one is present in the rack).
Power Down Considerations
To power off the equipment, ensure that network users are properly warned. No
specific order is necessary when powering off rack-optimized servers and
associated components. However, to do so in an orderly way, you should bring
down the operating system, then power off peripherals, then turn off servers.
WARNING The HP NetServer LH 6000r is connected to standby power
even when power is turned off. Do not open the system for
maintenance except if you have removed the power cord.
Refer to precautions regarding replacement of PCI cards in the
installation manual.
