This chapter provides site planning and basic safety information for installing the Cisco Metro 1500 series system. It includes the following sections:
This section describes site planning, which includes information on power requirements, equipment testing, preparing the site, and coordinating the installation process.
 |
Note Certain electrical or environmental modifications might need to be made and verified before the equipment can be installed. |
The Cisco Metro 1500 series system is available in two versions:
The DC-powered version requires a -48V battery-based supply. Table 2-1 describes the power requirements in different regions.
| Region | Power Requirements |
|---|---|
North America | 110 VAC, 60 Hz |
Europe | 220 to 240 VAC, 50 Hz |
The input ports use multimode, single-mode, or a combination of both types of cables depending on the customer application. The output ports use single-mode cables only.
The remote link must be tested to verify that it meets the specifications and to ensure proper operation.
The supplier of the fiber-optic cable may have a test report available. If no report is available, remote link tests must be performed to verify that parameters are within specifications. Table 2-2 lists the remote link tests required, the measurement the test is to be specified in, and the instrument required to perform the test.
| Remote Link Test | Specified In | Instrument Required |
|---|---|---|
Link optical loss at 1550 nm | Decibels referenced to 1 mW | Laser source at 1310 nm and 1550 nm and power meter or optical time domain reflectometer (OTDR) |
Distance | Kilometers | OTDR |
Return optical loss at 1550 nm | Decibels | Reflectometer or OTDR with reflectometer |
Use a detachable electrical cord with national certification (type SVT or SJT). One end terminates in a NEMA-style attachment plug rated for supply voltage (120V or 240V), and the other end attaches to an IEC 320-type appliance coupler.
 |
Warning This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit. |
This section describes the various tasks required for preparing your site for installation, and it indicates who (you or the Cisco authorized representative) is responsible for these tasks.
You and the Cisco authorized representative share the following site preparation responsibilities:
The Cisco authorized representative is responsible for the following installation tasks:
|
Note You and the Cisco authorized representative are jointly responsible for online testing. |
The Cisco authorized representative can use the following checklist to ensure that the site is ready for installation:
In addition to providing the necessary support personnel to help with the installation, you are responsible for the following site preparation tasks:
Use the following checklist to ensure that the site is ready for installation:
To assure correct and reliable operation of the system, be sure to follow all warning and caution marks in this guide.
If any problems occur, stop operating the system and follow these steps:
Step 2 Disconnect the power cords at the rear of the unit.
Step 3 Call your customer service representative.
Being careful to avoid humidity and dust, install the system horizontally in a clean environment. Air conditioning is required. Do not expose the system to direct sunlight or heat sources. Locate the system in a restricted area.
|
Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location. |
 |
Caution Any modifications to the site that are required for Cisco Metro 1500 Series system installation must comply with local building and electrical codes. |
Before switching this Cisco Metro 1500 series system on, make sure that it has been properly grounded through the protective conductor of the AC or DC power connector to a power outlet with a protective ground contact.
|
Caution There are many points inside the system which can, if contacted, cause personal injury. Be extremely careful when opening the housing. |
Any adjustments or service procedures that require operation of the system with the protective covers removed should be performed only by Cisco authorized service personnel.
If the system is not used as specified, the protection provided by the equipment could be impaired. This system must be used in a normal condition (in which all means for protection are intact) only.
The Cisco Metro 1500 series system operates with AC power ranging from 110 to
240 VAC or -48 VDC, depending upon the product version that you have ordered.
For operation in various countries, power cords specific to the country of operation will be supplied. For proper operation of the system, use the appropriate power cord.
|
Warning Class 1 laser product. |
Eye safety for the user of the system is guaranteed for both the remote and local output channel. Only remove the dust cover from the remote or local output channel (Tx) adapter for installation procedures.
