Installing HiPath 3550 and HiPath 3350 
 
This section contains information on how to install HiPath 3550 and HiPath 3350. This chapter describes the standard installation procedures for the basic system. Refer to Chapter 9 "Expanding and Upgrading HiPath 3000" for information about supplementary equipment and expansions.

4.2.3.1  

Selecting the Installation Site 

Selecting a site  
The customer usually has a preferred installation site in mind.
Make sure that the customer's site meets the following guidelines:
 •   To guarantee sufficient system ventilation, keep the area surrounding the housing clear as follows: allow 30 cm clearance on the left (for board replacement), and 10 cm clearance on the right, top and bottom of the housing.
 •   Do not expose the systems to direct sources of heat (for example sunlight and heaters).
 •   Do not expose the systems to extremely dusty environments.
 •   Avoid contact with chemicals.
 •   Take every precaution to prevent the formation of condensation on the system during operation. Systems covered with condensation must be dried before being used.
 •   Observe the environmental conditions specified in Section 2.11 "Environmental Conditions".
 •   Ensure that the installation site is in the immediate vicinity of an electrical outlet
 •   Allow space for a main distribution frame or other additional equipment.
 •   Install lightning and surge arrester equipment.
 •   Avoid standard carpeting, as it tends to produce electrostatic charges.
 •   Ensure that a distance of at least 40 in. (101.6 cm) is left between Siemens Enterprise Communications GmbH & Co. KG equipment and other electrical equipment. The National Electrical Code (NEC) requires 36 in. (91.44 cm) of clearance in front of electrical equipment and 40 in. (101.6 cm) of clearance from other electrical service equipment.
 •   Ensure that the equipment room for the system provides adequate space for installation and maintenance activities, including removing and replacing the cover). See Bild 4-48 for space requirements on the sides of the system. We recommend using a plywood backboard at least 0.5 in. (127 mm) thick and measuring at least 4 ft. (122 cm) by 4 ft. (122 cm.).

 Figure 4-51   HiPath 3550 and HiPath 3350 - Wall Attachment
 

4.2.3.6  

Grounding the System and the Main Distribution Frame 
Implementation guidelines in accordance with IEC 60364 and IEC 60950-1 must be adhered to during installation.
DANGER  
Risk of electric shock through contact with live wires  
If your personnel are not qualified to work on the low-voltage network (230Vac)  
you must hire a licensed electrician. The Section 1.8.1 "Connection to the Power Circuit" is to be adhered to.  

Grounding of the System  
NOTE:  
Because of their safety class, the HiPath 3550 and HiPath 3350 do not require additional grounding.  
If additional grounding is necessary due to specific national requirements (for example in Finland, Norway, U.S.), the wall housing HiPath 3550 and HiPath 3350 must be grounded by a separate ground conductor via the ground connection marked " ".  

USA and Canada: Design of the separate ground conductor  
The connector cables of systems HiPath 3550 and HiPath 3350 have a ground conductor. The system must also be grounded by a separate ground conductor. This grounding connection must meet the requirements of the relevant authorities (U.S. National Electrical Code, Canadian Electrical Code). Lay a separate ground conductor from the grounding point to the system's ground connection. The cross-section of the ground conductor must measure at least 14 AWG.

Grounding for the external main distribution frame  
The system ground and that of the external MDF must be set from the building's potential equalization bus in a star configuration.
 •   Not for U.S.:
   -   HiPath 3550: Shipments always include an MDFU (Germany only) and two grounding cables. Use one of the cables to ground the MDFU. It is not necessary to ground the connection between the MDFU and HiPath 3550 (see Figure 4-52).
   -   HiPath 3350: This system type does not require an external main distribution frame. The connection cables to the peripherals are attached directly to the boards and routed to the outside via a cable duct inside the housing.
   
DANGER  
Risk of electric shock through contact with live wires  
An external main distribution frame which requires grounding (if the existing ground connection is marked " ") must be grounded by a separate ground conductor (minimum cross-section = 2.5 mm2)  
 
    Refer to Figure 4-52 when replacing a customer system but maintaining the existing external main distribution frame.
 •   For U.S. only:
    The customer supplies a main distribution frame to complete the communications system. Mount and ground the MDF in accordance with the manufacturer's instructions.

Grounding an external main distribution frame  
 Figure 4-52   HiPath 3550, HiPath 3350 - Grounding an External Main Distribution Frame
 

4.2.3.7  

Installing the Boards 
Outside the U.S., the system is already equipped with the boards needed for the customer-specific requirements when the system is delivered.
In the U.S., you may need to install the boards.

Connecting to T1, PRI, or CorNet (for U.S. only)  
Caution  
The TST1 Module (HiPath 3550) can be installed only in conjunction with a listed channel service unit (CSU).  

4.2.3.8  

Laying the Line Network and Connection Cables

 SLA24N  
 SLC16N  
 SLMO24  
Route the 16 TW to the MDFU via the SU X8 and 8 TW via SU X9 (see Figure 4-54) using a standard cable (with 16 TW). Connect both cables (= 1 CABLU with SU connectors labeled 8 and 9) to the same jumper strip (25 TW).  
 Slot with any other peripheral board  
 •   Without an external main distribution frame (MDFU):
You can attach cables for the peripheral boards directly to the boards (see Figure 4-55 for the slip-on connectors) and route them to the MDFU through the cable duct inside the housing.
 •   With an external main distribution frame (MDFU):
Use CABLU S30269-Z41-A30 (Figure 4-53) to connect the peripheral boards to the customer's line network. As shown in Figure 4-55, you can connect the eight-pin slip-on connectors to the boards directly. The line network connects directly to the jumper strip.

Not for U.S.: HiPath 3350: Connecting the Cabling  
The integrated distribution frame in HiPath 3350 allows you to connect the cable network to the trunk and the stations using screw connections on slip-on connectors. The slip-on connectors (C39334-Z7089-C13) can be easily removed for easy system connection and disconnection.
The peripheral boards and optional boards contain a distribution frame component in the form of edge connectors on the boards.
The slip-on connectors for these edge connectors are supplied with the boards.
 Figure 4-55   Integrated Distribution Frame - Slip-On Connector Screw Connections
 
If you have an external main distribution frame (MDFU), use CABLU S30269-Z41-A30 (Figure 4-53) to connect the peripheral boards to the customer's line network. As shown in Figure 4-55, you can connect the 8-pin slip-on connectors directly to the boards. The line network connects directly to the jumper strip.

For U.S. only: HiPath 3550 and HiPath 3350: Connecting the Cabling  
If the boards are not already connected to the appropriate cables leaving the system, you need to connect them.
 •   The TST1 Module (HiPath 3550) connects to a customer-supplied channel service unit (CSU) using the supplied cable. The CSU offers the required additional primary protection.
 •   Each port on the STLS4 Module connects to an S0 bus using the supplied, silver-satin connector cord and a surface-mounted RJ21X jack. The surface-mounted RJ21X jack is not supplied.
    The signals must be reversed in the RJ45X jack. See Figure 3-76.
 •   The board in Slot 10 of HiPath 3550 connects using a special cable from the backplane to the main distribution frame (MDF).
 •   The remaining peripheral boards and options are connected by means of a mains distributor provided on the customer side or a comparable unit. This is where the MDF cables supplied are used (Octopus cable with Amphenol terminators). You select the output pattern on the Amphenol connector by which slip-on connector you use on each board edge connector.
 •   Note: The MDF cable reverses the signals coming from the board. This means that R/T on the board interface becomes T/R on the Amphenol connector.

HiPath 3550 and HiPath 3350: connecting the LAN cable for HXGS3  
LAN cables are connected to HXGS3 boards in a HiPath ... 3550 or HiPath ... 3350 according to the description in Section 3.3.4 "HXGS3, HXGR3".
 •   Electromagnetic shielding
    To ensure sufficient electromagnetic shielding (according to EN 55022), a shielded LAN cable must be used, or the LAN cable being used must already be shielded.
 •   Procedure: LAN cable shield contacts
   
 Step  
 Activity  
 1.  
Expose the external shield (D) by stripping the LAN cable sheath (A).  
Stripped length = approx. 30 mm.  
 2.  
Wrap conductive tape (C) around the exposed external shielding at least 1.5 times and use a cable binder (B) to attach it to the housing, maintaining a continuous conducting contact between the tape and the housing (see figure).  

4.2.3.9  

Attaching Ferrite 
To keep within the interference limit required by EMC Class B, you must attach ferrite to the following lines.

HiPath 3550 and HiPath 3350 power cables (wall housing)  
The wall housing's power cable must be guided through the C39022-Z7000-C7 ferrite sleeve that is included in the accessory pack. Position the ferrite sleeve as shown in Figure 4-56 so that you will be able to close the housing cover.
 Figure 4-56   HiPath 3550 and HiPath 3350 - Power Cable with Ferrite Sleeve
 

Digital and analog trunk and subscriber lines of the HiPath 3550 and HiPath 3350 (wall housing)  

 If  
 Then  
HiPath 3550  
 •   Trunk or subscriber line modules in "large" format:
Guide both standard cables from SUX8 and SUX9 (see Fig. 4-55 ) to the MDFU through two ferrite sleeves (C4-Z55-C39022) each. The ferrite should be placed as far inside the housing as possible.
 •   Trunk or subscriber line modules in "small" format:
Guide the trunk and subscriber lines of all ports connected on a board through a ferrite sleeve (C39022-Z7000-C6) twice, i.e. in a loop.
More than one trunk or subscriber line can be guided through a ferrit sleeve. You can guide as many lines through a ferrit sleeve as long as the ferrit sleeve can still be closed properly. These means there can be no gap between the two ferrit halves.
The ferrit sleeves should where possible be mounted in the cable duct. If the number of lines makes this impossible, the ferrite can be attached directly at the output of the cable duct.
HiPath 3350  
Guide the trunk and subscriber lines of all ports connected on a board through a ferrite sleeve (C39022-Z7000-C6) twice, i.e. in a loop.
More than one trunk or subscriber line can be guided through a ferrit sleeve. You can guide as many lines through a ferrit sleeve as long as the ferrit sleeve can still be closed properly. These means there can be no gap between the two ferrit halves.
The ferrit sleeves should where possible be mounted in the cable duct. If the number of lines makes this impossible, the ferrite can be attached directly at the output of the cable duct.  
If there are insufficient ferrit sleeves supplied in the accessory pack for all trunk and subscriber lines, additional ferrit sleeves must be ordered:
