WARNING
The total power requirement for the SRKA4 MP Server System exceeds
the 240 VA energy hazard limit that defines an operator-accessible area.
Only qualified service technicians should access the processor, memory,
power subsystem, and non hot-plug/hot-swap areas of the SKA4
baseboard.
Peripherals
Peripheral Bay
The chassis contains one peripheral bay for CD-ROM, DAT, and floppy drives. The peripheral
bay contains two smaller bays: a device bay and a configurable media bay.
Device Bay
The device bay accommodates either a 5.25-inch CD-ROM or a DAT drive. Only qualified
service technicians should remove and install components in the device media bay.
14 SRKA4/ISP4400 Server System Product Guide
Configurable Media Bay
The configurable media bay supports either one of the following configurations:
• A .5-inch slim line floppy drive and ½-inch slim line CD-ROM drive
• A 3.5-inch floppy drive
Only qualified service technicians should remove and install components in the configurable
media bay.
Hard Drives
The chassis contains up to one hard drive bay. The hard drive bay supports either one of the
following configurations:
• Five 3.5-inch by 1.0-inch hot-swap Adaptec Ultra 160/m SCSI SCA hard drives
• Three 3.5-inch by 1.6-inch hot-swap Adaptec Ultra 160/m SCSI SCA hard drives
Opening the front bezel door provides user access to the hard drives. As part of the hot-swap
implementation, each hard drive requires a hard drive carrier. When you remove a hard drive from
the system, you remove both the carrier and the hard drive. The drive is attached to the carrier by
four screws. The carrier is locked into the hard drive bay by a locking handle. Figure 4 shows the
orientation of the drive in the carrier. The carrier is upside down in this figure.

Each hard drive is connected to an Adaptec Ultra/m 160 SCSI hot-swap backplane. The backplane
provides industry-standard 80-pin SCA-2 connectors for each hard drive and accepts 10k or slower
drives that consume up to 23 watts of power. If another type or slower Ultra 160 SCSI SCA drive
is installed, make sure that the drive meets these backplane and carrier requirements.

✏ NOTE
All hard drives have different cooling, power, and vibration characteristics.
Intel has validated specific hard drive types in the SRKA4 chassis. The
SRKA4 Validation List contains a list of these manufacturers and hard drive
types. The document can be found on
http://support.intel.com/support/motherboards/server/SRKA4/compat.htm
An LED above each hard drive displays the status of that hard drive.
LED State Status
Solid green The hard drive is present and powered on.
Flashing green The hard drive is active.
Solid yellow There is an asserted fault status on the hard drive.
Flashing yellow A rebuild of the hard drive is in progress.
Off The hard drive is not powered on.
Power Subsystem
The SRKA4 MP Server System uses a universal input-switching power subsystem (PSBS). This
subsystem provides up to 630 Watts DC. The subsystem also minimizes the RMS current drawn
from each AC line by providing power factor corrected AC input. The chassis can be configured
with one, two, or three 350-Watt power supply modules, where each is designed to minimize
electromagnetic interference (EMI) and radio frequency interference (RFI).
The power subsystem consists of a power subsystem bay, up to three power supply modules. The
power subsystem bay contains a power distribution board, which manages the power delivered by
all functional power supplies.
The power subsystem can operate in either a nonredundant or redundant way. Operating in a
nonredundant way means that you are using only one or two power supply modules. If the power
supply module ceases to function normally, the server system cannot function properly, if at all. A
minimal configuration supported by one power supply module is one processor, four memory
DIMMs, one hard drive that is not 10K, one floppy drive, and one CD-ROM.
The safer approach is to use a redundant (2+1) power subsystem. To form a (2+1) redundant
power subsystem, the subsystem parallels the DC output of one power supply module with one or
two other modules. If one module ceases to function normally, the remaining modules provide
power to the server system and the system continues to function properly. Two power supply
modules are required to provide power to a fully configured SRKA4 MP Server System. The third
module provides redundancy. A fully configured system includes four processors, eight GB of
memory, one floppy drive, one CD-ROM, five hard drives, and eight PCI add-in boards.
WARNING
The total power requirement for the SRKA4 MP Server System exceeds
the 240 VA energy hazard limit that defines an operator-accessible area.
Only qualified service technicians should access the processor, memory,
power subsystem, and non hot-plug/hot-swap areas of the SKA4
baseboard.
16 SRKA4/ISP4400 Server System Product Guide
System Cooling
The SRKA4 MP Server System uses up to six fans mounted in a fan board assembly in the middle
of the chassis between the E-Bay and peripheral device bays. The six fans are noted by "A" in
Figure 5.
A
OM09938
Figure 5. Fan Board Assembly with Six Fans
The SRKA4 server cooling system supports either a non-redundant configuration or a redundant
configuration. A non-redundant configuration includes just three fans. If any one of these three
fans ceases to function normally, environmental conditions within the chassis may exceed the
environmental regulations in this guide and the chassis may not function normally. Three fans
support any system configuration but without fan redundancy.
Operating the server with a non-redundant cooling system is not recommended for systems
requiring high availability. To maintain SRKA4 MP Server System availability, Intel recommends
the use of all six fans to form a redundant cooling system. If one of six fans ceases to function
normally, the remaining five fans adequately cool the system. Using six fans supports any
configuration up to the maximum configuration. Six fans support a maximum set of components.
These components include four processors, 8 GB of SDRAM memory, five 10k hard drives, eight
PCI add-in boards, and at least two power supply modules.
Air flows in through the front bezel over the power subsystem bay, the peripheral bay, and the hard
drive bay. The air then passes through the fan board assembly and to the baseboard. Finally, the
air exhausts through the rear and left side of the chassis.
Individual fan status indicators are located on the fan board mounted in the fan board assembly.
Fan failure is also indicated by the general fault LED located at the front of the chassis.
WARNING
The total power requirement for the SRKA4 MP Server System exceeds
the 240 VA energy hazard limit that defines an operator-accessible area.
Only qualified service technicians should access the processor, memory,
power subsystem, and non hot-plug/hot-swap areas of the SKA4
baseboard.
CAUTION
The top cover must be on the system for proper cooling.

4 Removing and Installing User Serviceable
Components
A user can remove and install two components. They are:
• Hot-swappable SCSI hard drives
• Hot-pluggable PCI add-in boards
The term hot-swap describes the process of removing and installing a system component
WITHOUT shutting down the server. The term hot-plug describes the same process for
PCI components only.
When removing and installing the hot-plug and hot-swap components described in this chapter, a
user DOES NOT have to shut down the server.
WARNINGS
Hazardous conditions, power subsystem: Hazardous voltage, current,
and energy levels are present inside the power subsystem. There are no
user-serviceable parts inside it; servicing should be done by technically
qualified personnel.
The total power requirement for the SRKA4 MP Server System exceeds
the 240 VA energy hazard limit that defines an operator-accessible area.
Only qualified service technicians should access the processor, memory,
power subsystem, and non hot-plug/hot-swap areas of the SKA4
baseboard.
CAUTION
Electrostatic discharge (ESD) and ESD protection: ESD can damage
hard drives, add-in boards, and other components. This server can withstand
normal levels of environmental ESD while you are hot-swapping SCSI hard
drives. However, Intel recommends doing all procedures in this manual
only at an ESD-protected workstation. If one is not available, provide some
ESD protection by wearing an antistatic wrist strap attached to chassis
ground of the server—any unpainted metal surface—when handling
components.
25
SCSI Hard Drives
The system supports Adaptec Ultra 160/m SCSI SCA type or slower hard drives that are 3.5 inches
wide. Contact a sales representative or dealer for a list of approved SCSI devices.
Mounting a SCSI Hard Drive in a Carrier
1. Remove the 3.5-inch wide hard drive from its wrapper and place it on an antistatic surface.
2. Record the drive model and serial number in your equipment log (page 91).
3. Remove the carrier filler panel and save the screws. You need them later in this procedure.
4. Orient the drive so the connector is near the top and rear of the drive carrier. Figure 8 shows
the orientation of the drive in the carrier. The carrier is upside down in this figure.
5. Using the screws from step 3 or other screws of the correct size and length (not supplied),
attach the carrier to the drive.

Removing a SCSI Hard Drive
A bank of five LEDs on the front of the hard drive bays monitors the drive status of each drive in
the hot-docking bay. Each LED corresponds directly to a drive, so that the upper-most LED shows
activity in the upper-most drive. The LEDs and corresponding drives are numbered (left to right)
zero to four. When a yellow LED for a hard drive is on continuously, you are permitted to
hot-swap (replace) a bad drive with a good one. If the operating system installed supports
hot-swapping hard drives, the system DOES NOT need to be powered off.

Removing a Hot-plug PCI Add-in Board
WARNING
If the system has been running, any installed PCI add-in board on the
baseboard will be hot. To avoid the possibility of a burn, be careful
when removing or installing baseboard components that are located
near processors.
CAUTION
Slot covers must be installed on all vacant expansion slots. This
maintains the electromagnetic emissions characteristics of the system and
ensures proper cooling of system components.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Release the two thumbscrews located on the top rear of the chassis. One of two thumbscrews
is noted by "A" in Figure 13.

3. Using an even pull, press lightly on the top cover and slide it back until it stops.
4. Lift the entire top cover upward away from the chassis.
5. Make sure that the slot is powered off. If the slot is powered on, turn the power to the slot off
through the PCI Hot-plug application on your system or through the HW push-button.
6. Disconnect any cables attached to the board you are removing.
7. Press down on the PCI Hot-plug (PHP) Retention mechanism from inside the chassis. Rotate
the mechanism outside the chassis and towards the bottom of the chassis. This action frees the
card’s faceplate. See Figure 11 on page 29.
8. If you are removing a full-length board, release the Rear Retention Latch. See Figure 12 on
page 29.
9. Remove the PCI board by pulling straight up.
10. Store board in an antistatic protective wrapper.
11. If you are not reinstalling a board in the same slot, install a slot cover over the vacant slot. The
tapered foot of the cover must fit into the mating slot in the expansion slot frame.
