Hardware Installation
• Do not use the telephone to report a gas leak in the vicinity of that
leak.
• Ports that are connected to other apparatus are defined as SELV.
To ensure conformity to EN 41003, ensure that these ports are
connected only to the same type on the other apparatus.
Hardware Installation Procedure
1. Before handling the ISIHP card, discharge any static in your body
by touching a piece of grounded metal such as the computer
chassis.
2. Carefully remove the ISIHP card  from its antistatic bag, handling it
only by the mounting bracket and edges. Do not touch the gold-
plated connectors along the bottom edge. (You may want to save
packaging for possible future use.)
3. Visually inspect the ISIHP-2S/2U/4S/4U/4SD.  The 2S and 4SD
models  have only one daughter card, whereas the others have two.
If you have any concerns about the condition of your ISIHP  unit,
call Technical Support at (612) 717-5863.
