Location requirements
Œclean, dry, and well-ventilated to allow free airflow 
Œminimum clearance of 150 mm (5 in.) above and 100 mm (4 in.) below 
the ICS
Œthe gap between the ICS and the wall should be left completely clear 
to allow proper heat dissipation
Œtemperature between 0°C and 50°C (32°F and 122°F)
Œhumidity between 5% and 95%, non-condensing
Œminimum distance of 4 m (13 ft) from equipment such as 
photocopiers, electrical motors and other equipment that can produce 
electromagnetic, radio-frequency, and electrostatic interference
Electrical requirements
Œnon-switched, unobstructed outlet within 1.5 m (5 ft) of the ICS
Œdedicated 110 V - 120 V ac nominal, 50/60 Hz, 15 A minimum service 
with a third wire safety ground to provide shock protection and avoid 
electromagnetic interference  
ŒThe ICS power cord is 1.5 m (5 ft) long. You may connect the ICS to 
a power bar with a maximum length of two meters (6.5 ft), including 
power bar. The power bar must be approved by an appropriate 
National Test Body, with a third-wire ground. Do not use an extension 
cord between the ICS and the power bar, or between the power bar and 
the electrical outlet.
Risk of electric shock.
The safety of this product requires connection to an 
outlet with a third-wire ground. Use only with three-
prong power cord and outlet.

Norstar loop
Œone, two or three twisted-pair cable(s) per telephone
Œdc loop resistance of less than 64 Ω
Œcable length (0.5 mm or 24 AWG) less than 300 m (975 ft)
Œuse of a station auxiliary power supply (SAPS) for loops 300 m (975 
ft) to 1200 m (3900 ft). The SAPS must be a Class 2 power source that 
is approved by an appropriate National Test Body.
Œno bridge taps
ISDN S reference point (S Loop)
Œno longer than 1000 m (3,200 ft) for point to point
Œno longer than 450 m (1,475 ft) on a point-to-multipoint extended 
passive bus
Œno longer than 100 m (300 ft) for 75 ohm cable or 200 m (600 ft) for 
150 ohm cable on a point-to-multipoint short passive bus
Wiring for the S reference point (S loop) should conform to ANSI T1.605. 
Wiring for the ISDN U reference point (U loop) should conform to ANSI 
T1.601.
Verify lightning protectors.
Check the lightning protectors at the cable entry point 
to the building with special attention to the grounding. 
Report any problems to the telephone company, in 
writing.
Equipment that is designed to be connected using 
internal wiring is typically not lightning protected. 
Norstar telephone equipment and ISDN S loops and 
T loops should not leave the building where the ICS is 
installed.

Upgrading your system         
Only qualified persons should service the 
system.
The installation and service of this unit is to be 
performed only by service personnel having 
appropriate training and experience necessary to 
be aware of hazards to which they are exposed in 
performing a task and of measures to minimize 
the danger to themselves or other persons.
Electrical shock hazards from the 
telecommunication network and AC mains are 
possible with this equipment. To minimize risk to 
service personnel and users, the ICS must be 
connected to an outlet with a third-wire ground. In 
addition, all unused slots must have filler 
faceplates installed and the system cover must 
be locked in place at the completion of any 
servicing.
Service personnel must be alert to the possibility 
of high leakage currents becoming available on 
metal system surfaces during power line fault 
events near network lines. Risk points on the ICS 
are the Feature Cartridge, heatsink and power 
cord earth ground pin. These leakage currents 
normally safely flow to Protective Earth ground 
via the power cord. Therefore, it is mandatory 
that connection to an earthed outlet is performed 
first and removed last when cabling to the unit. 
Specifically, operations requiring the unit to be 
powered down must have the network 
connections (central office lines) removed first.

Upgrading a restricted Feature Cartridge
You can upgrade your restricted feature cartridge by entering a series of 
Software Keys you obtain from Nortel Networks. This will add an 
additional eight ports for Norstar telephones. Refer Software Keys on page 
255 for more information.
Upgrading from 16 telephones to 24 telephones
The third slot in the ICS is used for an 8-port Expansion Cartridge, with or 
without clocking. Installing a Clocking Cartridge (no expansion) does not 
add additional Norstar telephone ports. 
You cannot add the Expansion Cartridge to a system using a restricted 
feature cartridge that has not been upgraded.
1. Verify your system programming and update the Programming 
Record.
2. Disconnect all central office and station line connections from the ICS.
3. Remove power from your system.
4. Insert the Expansion Cartridge according to the Installation chapter. 
     
5. Power up the system.
6. Connect the central office and station line connectors.
When upgrading, Call Log information will be 
lost.
When the system restarts, Call Log information is 
not saved. Be sure to notify users if a system 
restart is planned so any log information can be 
written down first.
Risk of fire and electrical shock.
For continued protection against risk of fire and electrical 
shock, ensure all unpopulated cartridge slots are covered 
by filler faceplates prior to powering up. Immediately after 
powering up, connect the central office and station line 
connectors and replace the cover.

7. Replace the cover.  
Upgrading to Compact ICS 6.1
When you upgrade from a previous Compact ICS version to 6.1:
1. Verify your system programming, and update the Programming 
Record.
2. Disconnect all central office and station line connections from the ICS.
3. Remove power from your system.
4. Remove the Compact ICS Feature Cartridge.
5. Insert the Compact ICS 6.1 Feature Cartridge according to the 
Installation chapter.
    
6. Power up the system.
7. Connect the central office and station line connectors.
8. Replace the cover .
Removing an Expansion Cartridge cold starts 
the system.
If you remove the Expansion Cartridge or 
Expansion Cartridge with Clocking from the 
Compact ICS, you will lose all the system 
programming.
Risk of fire and electrical shock.
For continued protection against risk of fire and electrical 
shock, ensure all unpopulated cartridge slots are covered 
by filler faceplates prior to powering up. Immediately after 
powering up, connect the central office and station line 
connectors and replace the cover.

Upgrading Expansion Cartridge for BRI Card 
installation
The ICS must be equipped with an Expansion Cartridge with Clocking or 
a Clocking Cartridge to support BRI Cards.
The Expansion Cartridge with Clocking adds eight telephone ports in 
addition to clocking.
1. Disconnect all central office and station line connections from the ICS.
2. Remove power from your system.
3. Remove the Expansion Cartridge (without clocking).
4. Insert the Expansion Cartridge (with clocking) according to the 
Installation chapter.     
5. Power up the system.
6. Connect the central office and station line connectors.
7. Replace the cover.
