Installing the CPU

Introduction

You can install any standard CPU (BMEP58•0•0) or any Hot Standby CPU (BMEH58•0•0) in these racks:

BMXXBP•••• (PV:02 or later) X Bus rack
BMEXBP••00 or BMEXBP••02 Ethernet rack

Exception: You can install the BMXCPS4002 only on these dual-bus (Ethernet and X Bus) racks:

BMEXBP0602
BMEXBP1002

Installation Precautions

An M580 CPU is powered by the rack bus. Confirm that the rack power supply is turned off before installing the CPU.

DANGER

HAZARD OF ELECTRIC SHOCK

Remove all power sources before installing the CPU.

Failure to follow these instructions will result in death or serious injury.

Remove the protective cover from the rack slot connectors before plugging the module in the rack.

WARNING

UNEXPECTED EQUIPMENT OPERATION

Check that the CPU does not contain an unsupported SD memory card before powering up the CPU.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

NOTE: Check that the memory card slot door is closed after a memory card is inserted in the CPU, and remains closed during operations.

NOTE: Refer to %SW97 to check the status of the SD card.

Grounding Considerations

Follow all local and national safety codes and standards.

DANGER

HAZARD OF ELECTRIC SHOCK

If you cannot prove that the end of a shielded cable is connected to the local ground, the cable must be considered as dangerous and personal protective equipment (PPE) must be worn.

Failure to follow these instructions will result in death or serious injury.

NOTE: Refer to the ground protection information provided in the Electrical installation guide and Control Panel Technical Guide, How to protect a machine from malfunctions due to electromagnetic disturbance.

Installing the CPU

Install the CPU in the rack slots marked 00 and 01. If you do not install the CPU in these two slots, it starts in NOCONF state state and uses the default IP address, which starts with 10.10 and uses the last two bytes of the MAC address.

Follow these steps to install a CPU in a rack:

Step	Action	Illustration
1	Verify that the power supply is turned off.	–
2	If you are installing a Hot Standby CPU, on the back of the CPU, set the A/B/Clear selector switch to the appropriate selection, “A” or “B”. NOTE: When you later install the companion Hot Standby CPU, set its rotary switch to the other A/B position.	–
3	Verify that: if an SD memory card is used, it is supported by the CPU the connectors’ protective covers are removed the CPU is placed on the slots marked 00 and 01
4	Position the locating pins situated at the rear of the module (on the bottom part) in the corresponding slots in the rack.
5	Swivel the module towards the top of the rack so that the module sits flush with the back of the rack. The module is now set in position.
6	Tighten the 2 screws on top of the CPU to maintain the module in place on the rack. tightening torque: 0.7...1.5 N•m (0.52...1.10 lbf-ft).	–

Installing Modules in the Second Local Rack

If you are installing a Hot Standby system, you need to install the same collection of modules, with the same versions of firmware, that were installed on the first rack. Install each module in the same slot that its counterpart occupies on the first rack. Follow the same procedure described above, except set the A/B/Clear selector switch on the back of the standby CPU to other A/B position.

Connecting the Hot Standby Local Racks

If you are installing a Hot Standby system, you need to connect the communication link to CPU A and CPU B before applying power to either local rack. If you start up the CPUs before they are connected via the Hot Standby link, both CPUs attempt to assume the role of primary CPU in your Hot Standby system.

DANGER

HAZARD OF ELECTRIC SHOCK

Connect the functional ground (FG) terminal of the power supply module directly to the protective earth screw of the rack.
Do not chain the function ground (FG) terminals of redundant power supply modules together.
Do not connect anything else to the functional ground (FG) terminal of the power supply module.

Failure to follow these instructions will result in death or serious injury.

DANGER

HAZARD OF ELECTRIC SHOCK

Use only cables with ring or spade lugs and check that there is a good ground connection.
Make sure that grounding hardware is tightened properly.

Failure to follow these instructions will result in death or serious injury.

Before you connect the two Hot Standby local racks, verify that an equipotential grounding system is in place that includes the two racks (plus any other equipment you intend to connect to the two Hot Standby local racks).

NOTICE

UNINTENDED EQUIPMENT OPERATION

When installing modules with fiber optic transceivers, do the following to help prevent dust and pollution from disrupting light production into the fiber optic cable.

Keep caps on jumpers and transceivers when not in use.
Insert the optical cable into the transceivers carefully, respecting the longitudinal axis of the transceiver.
Do not use force when inserting the cable into the optical transceivers.

Failure to follow these instructions can result in equipment damage.

Each Hot Standby CPU includes on its front face an SFP socket. This socket can accept an SFP transceiver module for either copper or single mode fiber optic cabling of the Hot Standby link. Your choice of SFP transceiver and cabling is determined by the distance between the two Hot Standby local racks.
