Chapter 2 Controls, Ports, and Indicators
Rear Panel Controls, Ports, and Indicators
Refer to Figure 2-2 below to locate features on the NetServer’s rear panel:
• The Remote Management Port links the NetServer to a console for r eal-
time diagnosis of system operation .
• The Ser ial B Port is a standard serial port.
• The Ser ial A Port is a standard serial por t.
• The Parallel Port is a standard parallel port.
• The Mouse Port accep ts a stan dar d P C mouse.
• The Keyboar d P ort accepts a s tandard PC k eyboar d .
• The Monit or Port accept s a monitor wi th up to 1024 x 768 x 256
resolution, with a 60-75Hz video refresh rate. The NetServer contains
1MB of vi deo RAM.
• The NetServer comes with three 550W power supplies installed: two in
the left rear, and one in the right rear. The optional Redundancy Kit
provides a fourth power supply to install in the right rear. Since the
NetServer only requires three power supplies to run, installing a fourth
power supply prevents service i nterrupt ions from a sin gl e power supply
failure. With the Redundancy Kit installed a power supply can be
hot-swapped.
• The Power C onnector a ccep ts two sta nda rd power cables to connect the
NetSer ver with the site AC power source.

Chapter 2 Controls, Ports, and Indicators
Figure 2-2. Rear Panel and Port s
Connecting th e NetSer ver to AC Power
When you con nect t he NetS erver to an AC power source, t he server t emporari ly
draws additional current. This occurs even when th e system is in standby mode.
This "inrush current" is much greater than the server’s normal oper atin g n eeds.
Generally, your external AC power source can h an dle the inrush current.
If you install several NetServers on one cir cuit, however, precautions are
necessary. If there is a power failure and power is then restored, all the ser vers
immediately begin to draw inrush current at the same time. If the circuit br eakers
on the incoming power lin e have insufficient capacity, they may trip and thus
prevent the servers from powering u p .
When preparing your site for installation, allow for the additional inrush current.
Follow these circuit breaker recommendation s before installing the server at your
site:
7
Chapter 2 Controls, Ports, and Indicators
• In North Amer ican, use a 20-amp-minimum circuit with one NEMA AB1
class 14B breaker for each 16 -amp Power Distribution Un i t ( PDU).
• In Europe:
◊ For a single NetSer ver in a rack, use a 15-amp-minimum circuit with
one IEC MCB C-type breaker for each 16-amp PDU.
◊ For multiple NetServers in a rack, use a 15-amp-minimum circuit with
one IEC MCB D-type breaker for each 16-amp power distribution
unit.
Each 16-amp PDU can accommodate a maximum of two NetServers.
When the proper power supply is available, connect the NetServer to the AC
power source.
Power-On Tests
The NetServer runs a set of diagnostic tests when it is first connected to a power
source. If the NetSer ver passes the tests, you will see:

• Cover 1 cover s the side where the I/O board is located.
• Cover 2 covers th e area above the system boar d as s e mbly.
• Cover 3 covers the side wher e the p rocessor and memor y cages are
located.
The followin g sections describe removing the covers from the LH 4 and LH 4r.
WARNING Before removing covers, always disconnect the power cords
and unplug t elephone cables. Disconnect the power cords to
avoid exposure to high energy levels that may cause burns
when parts are short-circuited by metal objects, such as tools
or jewelry. Disconnect telephone cables to avoid exposure to
shock hazard from telephone ringing voltages.
Note that the power switch does not turn off the standby
power. Disconnect the power cord to turn off standby power.

4 Accessory Boards
The HP NetServer accepts PCI and I S A accessory boar ds connected to th e I /O
Board. An accessory board can be identified by the offset of the bracket and the
shape of the edge con nector (see Figure 4-1).
PCI Board- Left-Side Offset
ISA Board- Right-Side Offset
Figure 4-1. I/O Board with Devices and Bus Structur e
The I/O Boa rd
The I/O board is located under cover 1 and is sh own in Figure 4-2. The I/O board
contains:
• The Remote Managemen t connector, linking the I/O board to the external
conn ector on the rear panel.
• The I/0 Memory slot, which contains cache memory used by the Intel
i960RD I/O processor.
• The SE SCSI connector, wh i ch services an y sin g l e-ended SCSI device
installed in the internal (non-hot-swap) trays.
• The PCI Boa rd sl ot s , which are eig ht connect ors that accept PCI boar d s .
• The I SA Board slot, wh ich accepts a single I SA board. Th is slot is shared
with PCI slot 1. Either slot can be occupied, but not both.
• The two SCSI connectors, A and B.
17
Chapter 4 Accessory Boards
SCSI A has the following characteristics:
• By default, SCSI channel A is conn ected to the hot-swap mass
storage cage that was shipped with the NetServer. (For the HP
NetSer ver LH 4, SC S I A i s connected to t he r igh t cage; for th e HP
NetSer ver LH 4r, SCSI A is connected to th e lower drive cag e.
• By default, the integrated HP NetRAID subsystem is enabled for
SCSI A.
SCSI B h as the following characteristics:
• By default, SCSI channel B is connected to the non-hot-swap
devices. If you install a second h ot-swap mass storage cage, you
can connect it to SCSI B. There are two SCSI B connectors: one
SCSI B connector is designed for the single-ended (SE), non-hotswap devices; the other SCSI B connector supports Ultra2 (LVD)
drives. The two connectors are on th e same SCSI bus, but are
separated electrically by an LVD to SE converter. The slow
devices on SE are not affected by LVD operation. However, SE
devices and LVD devices cannot share a SCSI ID. To resolve a
conflict, change the SCSI address of the non-hot-swap device by
resetting its SCSI address switches.
18
• By default, the integrated HP NetRAID subsystem is disabled for
SCSI B. However, you may enable the integrated HP NetRAID
subsystem on SCSI B.
• If you enable HP NetRAID for SCSI B, all non-hot-swap SCSI
devices and all hot-swap drives in the second hot-swap mass
storage cage become par t of HP NetRAID.
• If you enable HP NetRAID for SCSI B, you cannot use devices
with multiple LUNs (logical units) in the non-hot-swap shelves.
An example of a device with multiple LUNs that you cannot use is
an autoloader tape device. If you want to use a device with
multiple LUNs and you want to enable HP NetRAID for SCSI B,
you must con nect t he device to a SCSI controll er access ory board.
• If you enable HP NetRAID for SCSI B, and you plan to use a tape
backup device, you m ust connect th e device to a SCSI controller
accessory board.
Chapter 4 Accessory Boards
NOTE If you enable NetRAID on only one channel, it is
recommen ded that you use the default configuration and
enable HP NetRAID on SCSI A. f you enable HP NetRAID on
only one channel, and later want to enable a second channel,
you must follow the instructions in the Integrated HP
NetRAID Controller Configuration Guide in the chapter on
configuring a secon d chann el.
