Device Bay The device bay accommodates either a 5.25-inch CD-ROM or a DAT drive. Intel strongly recommends NOT installing any device, such as a hard drive, requiring airflow cooling in the device bay.
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.
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.
Page 42
Each power subsystem auto-senses within the following voltage ranges and is rated as follows: 100-120 V at 50/60 Hertz (Hz); 11.0 A maximum 200-240 V at 50/60 Hz; 5.5 A maximum The DC output voltages of each power supply module are: +3.3 V at 28 A max (Total combined power of the +3.3 and +5 channels must not exceed 195W) +5 V at 32 A max (Total combined power of the +3.3 and +5 channels must not exceed 195W)
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.
An LED above each cooling fan displays the status of that fan. The LEDs for two fans are noted by "A" in Figure 20. The LED on the left indicates the status of the fan pointed to by the left arrow.
Narrow SCSI device. Both connections are not a standard part of the SRKA4 MP Server System. For a Legacy Wide or Narrow device, Intel provides two cables that can be routed to the peripheral bay on the front of the system. To purchase the cable, contact a sales representative. The Legacy Narrow connector can be routed to the peripheral bay.

Removing Individual Fans Cooling and air flow: Once you remove an individual fan, make sure you replace it within two minutes. If you cannot replace it, insert the original unit. When you have the replacement unit, repeat the replacement procedure. Vacant spaces formerly occupied by fans alter air flow patterns in the server system and may cause environmental conditions to exceed the environmental limits of the server.
Hard Drive Bay Removing the Hard Drive Bay 1. Observe the safety and ESD precautions at the beginning of this chapter. 2. Remove the front cover. See "Removing the Front Cover" on page 50. 3. Remove the fan board assembly. See "Removing a Fan Board Assembly" on page 62. 4.
7. With a flat head screwdriver, pry the right side of the hard drive bay out of the chassis. OM09959 Figure 33. Removing the Hard Drive Bay From the Chassis 8. Install the fan board assembly. See "Installing a Fan Board Assembly" on page 63. 9.
Peripheral Devices Removing a Drive from the Configurable Media Bay The configurable media bay holds either a 1.44 MB, 3.5-inch diskette drive OR both a .5-inch slim-line floppy and .5-inch slim-line CD-ROM drive. The drives are secured to the media bay by a screw.
All SCSI devices must not be terminated except the peripheral at the end of the SCSI cable. Hard drives usually provide an active termination, while CD-ROM drives do not. Because Intel recommends putting hard drives only in the internal bays, the SCSI cable should be routed so that the last device on the cable is a hard drive in the internal bay.
