Step	Activity
1.	Compare the components with the packing slip or customer receipt to make sure that they are correct and complete.
2.	Determine whether any damage has occurred during transport and report it to the proper departments.
3.	Dispose of the packing materials properly.

Caution   Only use tools and equipment that are in perfect condition. Do not use equipment with visible damage.

Step	Activity
1.	Use the template to drill the holes.
2.	Insert the wall anchors and screw in the screws, leaving 5 mm projecting.
3.	Remove the housing cover and mount the MDFU-E on the brackets.
4.	Tighten the screws through the holes.

Warning   To prevent injuries, you must observe the following instructions for the removal and attachment of the HiPath 3550 and HiPath 3350 housing cover.

Step	Activity
1.	Loosen the two screwed plugs on the housing cover with a slotted screw driver. Hold the housing cover so that it does not fall.
2.	Remove the housing cover.   Warning   Grasp the housing cover by its outside walls only.   The shielding plate on the inside of the cover may have sharp edges which can cause cuts.

HiPath 3550 and HiPath 3350 - Wall Attachment

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 1.6.1 "Connection to the Power Circuit" is to be adhered to.

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 " ".

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)

Caution   The TST1 Module (HiPath 3550) can be installed only in conjunction with a listed channel service unit (CSU).

HiPath 3550 - Backplane connection for peripheral board

If	Then
SLA8N    SLA16N    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.

Integrated Distribution Frame - Slip-On Connector Screw Connections

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).

HiPath 3550 and HiPath 3350 - Power cable with ferrite sleeve

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 (C39022-Z7000-C6) 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 ferrite sleeve. You can guide as many lines through a ferrite sleeve as long as the ferrite sleeve can still be closed properly. These means there can be no gap between the two ferrite halves. The ferrite 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.

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 ferrite sleeves supplied in the accessory pack for all trunk and subscriber lines, additional ferrite sleeves must be ordered:    •   L30460-X1358-X-* (direct sales) / L30251-U600-A229 (export): Contains 5 ferrite sleeves C39022-Z7000-C6  •   L30460-X1359-X-* (direct sales) / L30251-U600-A230 (export): Contains 9 ferrite sleeves C39022-Z7000-C6

Restrictions for equipment with IVMP8, IVMS8, TST1 and TS2N boards must be observed.

HiPath 3350 (see Figure 4-61)	2 / 3 (CBCC)	24 erlangs	56 erlangs
	4	16 erlangs
	5	16 erlangs

1Use of a TS2N board results in a capacity of 30 erlangs. A maximum of one TS2N per HiPath 3550 is possible, and the board may only be installed in slot 7 or 9, thus resulting in 30 Erlangs for slot 7 or 9.

Caution   Conduct the visual inspection only while the system is disconnected from the power supply. Always wear an antistatic wristband and observe the measures for protecting electrostatically sensitive devices (see Section 1.2.6 "Notes").

Step	Activity	Resources/Remarks	Possible remedies
1.	Compare the slots for the installed boards with the board assignment map.	Board assignment map	Correct the board configuration and notify the sales department.
2.	Check the local line voltage.	Digital multimeter

After finishing the visual inspection, you can begin starting up the system as described in Chapter 5 "Starting Up HiPath 3000".
