If damage occurred in transit, notify the carrier as well. Hewlett-Packard will arrange for replacement or repair without waiting for settlement of claims against the carrier. If the shipment was damaged in transit, keep the shipping containers and packaging material for inspection. If extensive damage is found, it may be necessary to return the entire cabinet to HP. Refer to the Repacking instructions.

Cabinet Installation

Installation of a factory-loaded cabinet consists of the following steps:

Move the cabinet to installation site.

Lower the leveling feet. (This will prevent excessive wear on the casters.)




	CAUTION: Extend the cabinet stabilizers, located at the bottom of the front of the cabinet, as an additional safeguard against overturning the cabinet during installation. Failure to observe this precaution could result in personal injury or equipment damage.

Connect the console and system peripherals to the server.
For information about connecting external devices, refer to “External Connections” at the end of this section.
NOTE: Attaching cables while the rails are extended fully forward will ensure that sufficient slack is available for later maintenance.
Connect the cabinet power cord to the appropriate wall outlet.
NOTE: If the cabinet being installed contains a PowerTrust Uninterruptible Power Supply (UPS), perform the steps shown under the “PowerTrust UPS Option ”Option subsection.
Be sure all peripherals outside the cabinet are connected to wall outlets.

The cabinet/server system assembly is now ready for the power up process. Refer to the section titled, “A-Class Server Power Up and Boot Procedures”.

PowerTrust UPS Option

Unpack the PowerTrust UPS and read all the installation information in the PowerTrust System Guide, part number 5961-8383. Once all the procedures listed in the UPS guide are complete, perform the following steps to complete the UPS installation with the cabinet.

Position the UPS next to the cabinet on the floor.
Remove the jumper cord from the SPU to the PDU inside the cabinet.
Install one of the convenience cords (output cord) that came with the UPS into the AC receptacle in the back of the SPU.
Place the other end of that cord into one of the Output outlets in the back of the UPS.
The other convenience cord is connected between the UPS and the system console.
Locate the appropriate input line cord for the UPS in the supplemental package shipped with the UPS.
Plug the UPS into the appropriate wall outlet.
The system should now be ready for power up. Refer to the section titled, “A-Class Server Power Up and Boot Procedures”.

Repackaging the Cabinet for Shipment

Use the original packing material to repackage the cabinet for shipment. If the packing material is not available, contact your local Hewlett-Packard Sales and Support Office regarding shipment.

Before shipment, place a tag on the container (or equipment) to identify the owner and the service to be performed. Include the equipment model number and the full serial number, if applicable. The label showing the model number and the full serial number is located on the outside of the rear door.

Due to the weight of a fully loaded cabinet, it will require two people to push the cabinet up the ramp onto the pallet.

WARNING!

Repackaging a loaded cabinet may be hazardous because a fully configured 2.0 meter cabinet can weigh up to 362.8 kg (800 lbs). Always use two people when moving the cabinet and when positioning the cabinet on the pallet. Check the condition of the loading/unloading ramp before use. If the ramp appears damaged, DO NOT attempt to push a loaded cabinet up the ramp onto the pallet. Contact your local Hewlett-Packard Sales and Support Office regarding shipment. Failure to heed this warning can result in serious injury or equipment destruction.

To repackage the cabinet, follow the repacking checklist and refer to the unpacking instructions for detail.

Repacking Checklist:

C2786A	Field	1.6m x 19"	16	A5214A
C2787A	Field	2.0m x 19"	20	A5214A

Cabinet Loading Requirements

A-Class servers require two EIA of cabinet space (each two EIA of space is equivalent to the height of a server without the server's "feet"). Ensure that the cabinet has this amount of space available.




	NOTE: Replace the rubberized feet on the server with plugs provided in the cabinet mounting adapter kit.

Fill empty cabinets from the top down, with A-Class servers on top. If you are mounting one or more servers into an empty cabinet, start at the inside top of the cabinet and count down four of the holes in the columns at each corner to determine the position of the rails for the first server. When the first rails are installed, continue to use the four hole requirement as your guide for installing additional A-Class servers.

Refer to the Rail Kit Installation Sheet (A5214-96001) for instructions necessary to install rails in the HP computer cabinet.

Mounting the Server

To mount the server in the cabinet, follow the procedure listed below:

From the front of the cabinet, slide the server onto the rails. Push the server into the cabinet until approximately three inches of the server remains protruding from the front.
Install sheet metal nuts on the left and right front columns and align with front anchor bracket slots.
Install the left and right front anchor brackets on each side of the server as follows:
- Insert each hooked tab into its slot on the bottom of the front corner of the server.
- Hold the tabs upright and slide the server all the way into cabinet until the tabs butt up against the columns on each side.
Fasten the both front anchor brackets securely to both front cabinet columns with the prepositioned sheet metal nuts.
Attach a plastic end cap to each anchor bracket.
At the rear of the cabinet, position the rear rail mounting clamps on each rail at the back of the server. Tilt each clamp forward slightly and slide the angled tab completely into the available slot in the server so that each clamp sits flat on the rail.
Fasten each rear mounting clamp to its rail with the screws provided.

When you are ready to connect external devices, refer to “External Connections” for further information.

External Connections

External devices are interfaced with the A-Class server by means of specific connectors located in the rear of the server. Exterior connections to the server include ports for:

Small Computer System Interface (SCSI) devices
System Consoles
Local Area Networks (LANs)
Power Cords.

Connect External Small Computer System Interface (SCSI) Devices

Connect external SCSI devices to the Single Ended SCSI bus (labeled SCSI (Single-Ended) 8/16/5) on the system card or to additional SCSI interface cards. If external devices will not be connected to the SCSI bus, make sure the terminator (1252-3932) is in place.

Make sure all devices on the SCSI bus have a unique address and the last device is terminated. Refer to the documentation accompanying each device to learn how to set addresses and where to place terminators.

Connect external DDS (Digital Data Storage) tape and DVD/ CDROM drives to A-Class servers as shown in the diagram below. Connecting these devices in this manner reduces the likelihood of excessive parity errors and unexpected interrupts from occurring on the SCSI bus.

Connect a System Console

Using the ASCII Terminal as a System Console. If an ASCII terminal is to be used as a system console, connect it to the back of the server with a 24542G cable by attaching it to the 9- pin male connector labeled, Console 8/16/4.0.
Make sure the keyboard is connected and a power cable is available.
NOTE: When the web console is used, the RS232 Console Port (8/16/4.0) is disabled

Using the Web Console as a System Console. If the Web Console is to be used as a system console, connect an RJ45 LAN cable to the RJ45 connector labeled, LAN Web Console, on the back of the server.




	NOTE: The Web Console has a default Internet Protocol (IP) address of 192.0.0.192. Make sure that no other device, including other A-Class servers, has this address before connecting the A-Class server to your LAN.

Connect the Core Local Area Network (LAN)

Connect the 100baseT Core LAN on the system board to your LAN by using an RJ45 LAN cable. Connect the RJ45 LAN cable to the server by attaching it to the RJ45 connector labeled, 10/100 Base-T 8/0/20/0.

Connect Power Cords




	CAUTION: Do not press and hold the Web Console Reset button (located on the rear of the server between the LAN Web Console receptacle and the ASCII terminal receptacle) while connecting the server power cord. Failure to observe this precaution will cause erasure of all settings in the Web Console that is connected to the server.

Connect the power cord that is provided with the system to the server. For stand-alone servers, the power cord will be localized to each country's power application. If an HP Uninterruptible Power Supply (UPS) is the power source, use the power cord provided with the UPS. If an HSC Remote Management card is installed in the server, use the cable provided with the HP UPS to connect the RS232 serial port to the port labeled "UPS" on the HSC Remote Management card.

Connect power cords to all external devices at this time with the localized power cord, cabinet power cord, or the UPS power cord.

For cabinet mounted servers, the server power cord connects to the C13 connector of the Power Distribution Unit in the cabinet.
