Important Safety Precautions for Hardware Installation

It is important that you read this section before attempting any of the hardware installation and maintenance procedures in this guide.

Physical Safety Precautions

The following instructions are important for your safety and for the functioning of the HP OpenCall SS7 platform. Read the instructions carefully before attempting the installation.




	WARNING! Ensure that the hardware you are working with (TSU, SIU or host server) is disconnected from the power supply during installation until you are told to connect to a power source.

To avoid personal injury and damage to the product, power to the unit must remain switched off during installation until it is necessary to switch the power on. This means that the unit’s power cable and network cables must remain disconnected until you are instructed to make the connections. Follow the instructions in the procedures carefully.

This equipment is disconnected from the power supply by removing the power cord from the power outlet. It is therefore important to locate the unit close to a power outlet that is easily accessible.

For your safety, never remove the cover of a TSU, SIU or server while the unit is connected to a power source or to a telecommunication network. Always replace the cover before switching on the power to the unit. The terms POWER OFF and POWER ON are used to instruct you when to switch the power off and on respectively.




	WARNING! When told to connect a hardware unit to a power supply, for your safety you must always connect it to a grounded wall outlet.

Always use the power cord supplied with the TSU or one with a properly grounded plug (a DC powered TSU must only be used with the HP J3401-60201 power cord). If a power cord is not supplied, select the proper power cord according to your local national electric code. Ensure that the cable meets your country's standards for safety. For example:

USA - use a UL listed type SVT detachable power cord.
Canada - use a CSA certified detachable power cord.

Anti-Static Precautions

The HP OpenCall SS7 platform contains electrical components which can be damaged by static electricity. To avoid damage:




	CAUTION: Use an anti-static mat and wear a grounding wrist strap attached to the chassis of the server cabinet when removing and inserting components.

The server cabinet must be independently grounded so that when you remove the power cable any static charge passes to ground.
The mat and strap are available in the HP 9300-1155 Workstation Kit. All components must be placed on an anti-static mat if you have taken them out of their anti-static bag.
Avoid carpeting and clothing that produce static charges (wool, nylon, silk) and avoid unnecessary movements.
Do not touch components on the cards. Handle the cards only by their edges, face plates or extractor levers. When inserting or removing printed cards, do not touch any other components.

Saving Your Configuration




	CAUTION: Before performing any of the HP OpenCall SS7 hardware procedures in this guide, save your current configuration using the cfgMgr -copy command. Save your new configuration using the cfgMgr -copy command after completing the installation.
