The ONS 15305 can be installed in a restricted access location (RAL) or outside of an RAL.
4.4.1.1 Restricted Access Location
A restricted access location is a site location for equipment where the following criteria apply:
•Access can only be gained by service persons or by users who have been trained on the restrictions and the precautions for this specific site.
•Access is by means of at least one of the following, special tool, lock and key, or other means of security.
After installation in a RAL, such as in a telecommunications center, the ONS 15305 must be properly installed in a rack with brackets or in other ways properly connected to a safety ground. The ONS 15305 48-VDC power must not be powered from a source external to the RAL. The E1 interface used should be limited to SELV.
4.4.1.2 SELV Circuits
Safety Extra-Low Voltage (SELV) circuits are ports that have maximum DC working voltage level less than 60 V (42.4 VAC). In addition, the ports must not be connected to telecommunication networks as defined in EN 60950 (see CEI/ IEC 60950-1 2001-10, standard clause 1.2.13.8).
In practice, the electrical cables do not exit the building; electrical cables connect to equipment that meets one of the following requirements:
•Installed in the RAL
•Does not have electrical cables that exit the building unless those ports are TNV (Telecommunication Networks Voltage) circuits
•Has a written consent (or in other evidence) that its connecting port towards the SELV circuit port is not a telecommunication network
4.4.1.3 Telecommunication Network
A telecommunication network is a metallically terminated transmission medium intended for communication between equipment that might be located in separate buildings, excluding:
•Main system for supply, transmission and distribution of electrical power, if used as a telecommunication transmission medium
•Cable distribution system
•SELV circuits connecting units of information technology equipment
4.4.1.4 TNV Circuit
A TNV circuit in the equipment to which the accessible area of contact is limited. A TNV circuit is designed and protected that, under normal operating conditions and single fault conditions (see CEI/IEC 60950-1 2001-10, standard clause 1.4.14), the voltages do not exceed specified limit values.
4.4.1.5 Installation Outside of a Restricted Access Location
After installation in a non-RAL location, the ONS 15305 -48 VDC power and all communication ports must be connected to SELV circuits, for example, a port on a personal computer or 10/100-Mb Ethernet hub/router or other information technology (IT) equipment. The 48-VDC power must not exceed 60 VDC, and must be powered from a certified external power supply unit (PSU) or a battery unit (with no connection to -48 V telecommunications voltage).

4.5 Installation of Service Modules
This section describes installation procedures that are common to all service modules. For details on each service module, see the separate chapters.
There are no fixed positions for specific modules. It is possible to freely mix the four interface modules.
Note Due to a heat/power dissipation related to the 8xS-1.1-LC module, only two 8xS-1.1-LC modules can be installed inn the ONS 15305 chassis. This restriction only applies to the 8xS-1.1-LC module.
Insertion or withdrawal of new modules does not affect the other modules. No manual configuration is needed if a module is replaced with a module of the same type.
It is possible to protect a module by adding a redundant module in the chassis.
All modules store inventory data in non-volatile memory. The inventory data is accessible from the system controller and the management system.
All modules contain a LED that indicates the status of the module. The LED is green when the module is active. The LED is red if the module has failed. The LED is extinguished when the module is deactivated.
All modules supports hot insertion and removal. When replacing a module, activate the switch and wait for the LED to extinguish before removing the module. It is also possible to deactivate the module from the CiscoEdgeCraft terminal. The Card Extraction Tool is required.
The following service modules are described in separate chapters:
•Octal optical S-1.1 module (8xS-1.1-LC)
•Dual optical S-4.1 module (2xS-4.1-LC)
•Single optical S-16.1 module (1xS-16.1-LC)
•Dual optical LAN 1000Base-LX module (2xGE-SM-LC/RJ45)
•Octal LAN 10/100Base-TX module (8xFE-RJ45)
•Octal E1 tributary module (8xE1-RJ45)
•Hex E3/T3 tributary module (6xE3/T3-1.0/2.3)
•High density 63xE1 module (63xE1-LFH)
•Dual Optical S-1.1 module (2xS-1.1-LC)
4.5.1 LEDs
Each service module has one status LED indicator on the front of the module.
A red LED indicates a faulty module. The module can be removed. A red indication is also given during
power-up or re-booting of SYSCONT.
A green LED indicates that a module is in service. If the green LED is turned off, the module is out-of-service and can be removed.
Figure 4-4 LED for Module Failure Located in Lower Left Corner
A module is taken out-of-service by an operator shutdown command or by activation of the shutdown button.
Note On Ethernet-related modules, the LEDs flash green during shutdown.
4.5.2 Hot Insertion and Removal
The ONS 15305 service modules supports hot insertion and removal. Each module contain a switch that should be activated before the module is removed. A special tool, called the Card Extraction Tool, must be used to activate the switch.
Figure 4-5 Removal Switch
When the LED has extinguished the module can be removed.
Caution When activating the switch, ensure that is not pressed to far in.
It is also possible to deactivate the module from the craft terminal, CiscoEdgeCraft.
When the switch is activated, the module is disabled in SW, and the MOD FAIL LED is switched off (for modules carrying IP, the LED blinks during SW cleanup and extinguishes afterwards).The module can now be removed. Figure 4-6 shows the card (module) extraction tool.
