When the MCPA requires serviceOnly service personnel trained to install and remove this equipment are authorized to move this product to a different location. All service must be performed by trained personnel only. Covers for this product can only be removed by trained service personnel.Disassembling or modifying this product except as described in procedures provided by Hitachi voids the product warranty.If service is required, contact your Field Engineer or Hitachi Technical Assistance Center (TAC) at 770-446-8836 for instructions. Service is required when any of the following circumstances occurs:There is damage to the equipment.There is smoke or odor coming from the product.Liquid enters the equipment.A heavy object falls on the equipment.Operation is not normal as described in these instructions.The equipment gets dropped or falls.Technical supportAfter following the procedures in this document, if the product is still not functioning properly, contact the Hitachi Technical Assistance Center (TAC) at 770-446-8836.Cleaning instructionsFollow these guidelines when attempting to clean the equipment.CAUTION!For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.IMPORTANTDo not return equipment for warranty or repair service until you have received proper shipping instructions from Hitachi.WARNING!Improper cleaning can cause damage to the equipment. To prevent inadvertently damaging the equipment during cleaning, follow these guidelines when cleaning the equipment or in its vicinity:• Do not use a liquid cleaner, solvent, or an aerosol cleaner.• Use only blown air or equipment that has been specially designed for cleaning computer equipment to clean this equipment.• Surfaces may be cleaned with a soft, dry cloth.

System Configuration Requirements MCPA 1900 MHz 90 Watt MCPA Product Manual3-2 80088-CST-000-00d, January 29, 2009System Configuration RequirementsA PC is required for connecting to a Hitachi Multi-Carrier Power Amplifier to run the MCPA Monitor software. You can only connect to one MCPA at a time. The MCPA Monitor software cannot monitor more than one MCPA concurrently.The following software is required:Microsoft Windows XP® (SP-2) orWindows 2000The following configurations are recommended:Windows XP:PC: Processor clock ≥300 MHzRAM: ≥128 MBHDD: ≥2.1 GBWindows 2000:PC: Processor clock ≥133 MHzRAM: ≥64 MBHDD: ≥2.1 GBIMPORTANT!The computer you use with the MCPA Monitor must have a DB-9 serial (RS-232) port with a logical COM port to connect to the MCPA. If your computer does not have a serial port, you can use a high-speed USB-to-serial adapter with software that creates a virtual COM port connection for the adapter, also known as a smart USB-to-RS232 adapter. Follow the manufacturer’s installation instructions that accompany the device before installing the MCPA Monitor software, and be sure the adapter is connected to the same COM port each time you use it to connect to the MCPA Monitor.

MCPA Module Alarms MCPA 1900 MHz 90 Watt MCPA Product Manual6-2 80088-CST-000-00d, January 29, 2009MCPA Module AlarmsAll module alarms that occur in a Hitachi MCPA subrack are routed to the Alarm Interface Block Module and are identified as either a major or a minor alarm; and then the appropriate alarm signal is sent to the Alarm Interface Block connector. The Alarm Interface Block connector is a DB-9 female and has both normally open (NO) and normally closed (NC) wiring points that notify the NOC of the presence of major or minor alarms in the MCPA subrack. When the alarm circuit for the MCPA system is connected to the Alarm Interface Block, the NOC receives an alarm severity notification through the relay interface. Determining which specific module contains a fault condition can only be done when a technician is on site. Once on site, the technician can identify which module is in an alarm condition by checking the LEDs on the individual subrack modules. The technician can also obtain additional alarm information for the MCPA Amplifier Module by using the Hitachi MCPA Monitor software.To avoid damage to the MCPA module, major alarm conditions cause the MCPA module to be automatically shut down. When the MCPA module detects a minor alarm, it continues operating. The dry-contact relay is open when an alarm condition is detected through the Alarm Interface Block connector. Depending on the alarm, the MCPA module either automatically recovers or may require a reset. Note: You can view alarm details using the MCPA Monitor software. Refer to the “MCPA Monitor Windows” on page 5-3.Note: The notification method to the BTS for all the alarms is dry contact.The following table describes the MCPA module alarms.Table 6-1: MCPA module alarms (Sheet 1 of 2)Alarm Description Type Parameters Spare Unit in Use?LEDsALM (Red)ACT (Green)Over Temp Over temperature Major >56°C (133°F) (ambient)YONOFFMinor >53°C (127°F) (ambient)YONONGain Abnormal gain Major >6 dB error Y ON OFFIMD Insufficient Intermodulation correction Major Y ON OFFOverdrive Input overdriveaMajor >10 dB N ON OFFMinor >1.0 dB N ON ONExternal PS Abnormal external DC voltage bMajor <22.5V, >28V Y ON OFFMinor >22.5V, <25.5V Y ON ONInternal PS Abnormal internal DC voltageMajor Y ON OFF

Policies and Requirements MCPA 1900 MHz 90 Watt MCPA Product ManualB-2 80088-CST-000-00d, January 29, 2009Policies and RequirementsThe Return Material Authorization (RMA) process facilitates the repair and return of MCPA equipment. There are two acceptable initiators of the RMA process:Request from an Authorized Purchasing Agent of the Buyer to determine warranty statusRequest from an Authorized Technical Support Representative for failures that occur in the field during the acceptance periodHitachi Telecom (USA), Inc. reserves the right to modify or amend the Repair and Return policies with written notification to the Buyer at least 90 days in advance.RequirementsMake all repair and return requests to the Hitachi Technical Assistance Center (TAC) by contacting 770-446-8836. The Sales Administrator provides a copy of the RMA Packaging and Handling Guidelines and RMA number(s). ExceptionsAny equipment that is modified by someone other than an authorized Hitachi technician or damaged by causes other than defects in parts or workmanship, including but not limited to power surges, lightning strikes, water damage, accidents, abuse, neglect, vandalism, acts of God, or any other use contrary to the specifications or instructions provided by Hitachi Telecom, can be rejected. If rejected, Hitachi notifies and invoices the Buyer for any advance replacement equipment. Any equipment that is not returned in accordance with the Hitachi RMA Packaging and Handling Guidelines, including proper ESD packaging, is subject to rejection.Shipping costsThe shipping cost policies are as follows:The Buyer pays all shipping costs if the RMA is rejected. Hitachi pays shipping costs outbound to the customer for all in-warranty requests. The Buyer pays all shipping for any out-of-warranty requests.Advance replacement policyHitachi Telecom’s standard policy for replacing equipment is based on the Buyer’s Technical Support Agreement. The Agreement can require the receipt of the defective equipment prior to shipment of replacement equipment. However, if Hitachi determines the need is urgent, an advance replacement can be immediately shipped to the Buyer. The Buyer must return the defective equipment within 30 days or else a full invoice for the advance replacement equipment is issued. IMPORTANT!Equipment must be returned in accordance with the RMA Packaging and Handling Guidelines in order to be accepted.
