This section provides instructions before installing OMS 870 unit.
NOTE! The instructions in this section primarily address the
installation of the OMS 870, and modules supplied by
Ericsson . Codes and regulations for installing racks,
electrical wiring, raceways, and other equipment are not
covered in this manual,
Caution!
Wear a grounding wrist strap while unpacking, handling and
interconnecting the OMS 870 equipment modules to discharge
any static buildup.
1.4.1 Installation Overview
You should be thoroughly familiar with the instructions in this
manual before starting any work. Use the following general order of
work when installing a site:
1. Read and observe a ll safet y cautions and warnings in Ch apter 1,
“Safety Summary.”
2. When you arrive at the site, first verify the OMS 870 equipment
according to the procedures in “Pre-Installation Procedures” on
page 1-1. If there is a problem with the equipment, use the
dedicated contact resources for your support
3. If you do not install the equipment when it arrives, store as
specified in “Unpacking” on page 1-3
4. Unpack equipment only after preparing the site as described in
“Site Preparation” on page 1-2
5. When installing equipment at a site, follow the procedures in this
chapter in the order presented.
6. Make connections using the information in “Interconnections and
cable handling” on page 1-19

1.4.2 Installation Planning
Based on the system to be installed, determi ne the size , numbe r
and location of racks, the OMS 870 requires. The OMS 870 will fit in
485 mm (19-in.) equipment racks, and can be adapted for 600 mm
ETSI (23.6-in.) racks. The racks must be accessible from the front
and rear for equipment installation.
NOTE! You need 500 mm (19.6-in.) space of rear access for
installation of the equipment.
NOTE! The interfaces cables (especially E1 interfaces) must not run
in the same pipes as the power cables
Warning!
If mains AC power feeding is employed, the socket outlet shall
have protective earth and be installed near the equipment and
be easily accessible.
Plan rack and unit installation based on the following
considerations:
• Install the lowest unit in a rack first.
• Determine wire size based on cable length and local engineering
standards and practices.
• Plan the power cable from the power distribution panel (PDP) to
units, proceeding down along the right side of the equipment
rack.
• Plan grounding cable runs from the ground window down along
the right side of the rack to the units.
• Plan to route the electrical cables to and from the units along the
right side of the rack to the overhead cable transport tray.
• Plan to route the optical cables to and from the units along the left
side of the rack to the overhead cable transport tray.

Recommended items
To install an OMS 870 system, customary installation and electrical
tools are required. The following items are also recommended:
• Multimeter
• Phillips screwdriver (PH3) to attach the OMS 870 to the rack, and
Phillips screwdriver (PH1) to attach the brackets to the OMS 870,
• Pozidrive (PZ3, PZ1) as an alternative screwdriver
• Allen wrench
• Yellow green flexible ground cable (1.25 - 2.50 sqmm, 16 - 14
AWG)
• Cletop cleaning cassette (type A for SC connectors)
• Video fiber connector inspection instrument
• Caps for optical connectors
• Plugs for optical adapters
•Tie wraps
1.4.3 Installation Guidelines
When installing OMS 870 equipment into racks, follow these
guidelines:
• Consider the effect of additional electronic equipment and its
generated heat on the OMS 870 system equipment.
• Make sure the equipment rack is properly bolted to the ground
and, if required, to the ceiling.
• Ensure that the weight of the equipment does not make the rack
unstable.
• When mounting the equipment between two posts or rails,
ensure that the minimum clearance between the sides is 485 mm
(19 in.).
• Maintain a minimum clearance of 500 mm (19.7 in.) in front of the
equipment and 500mm (19.7 in.) at the back of the equipment.
Grounding Considerations for 48 V
It is vital that the OMS 870 is properly grounded. The OMS 870 can
be connected to ground in the power connector.

For location of the power connector on the OMS 870, see Figure 1
Figure 1 Location of the power connector on the OMS 870
1.4.4 Power Considerations
The OMS 870 can be powered using a regular telecommunication
power supply of –48 VDC with a VDC return. Two independent
power supplies can be attached to the OMS 870 equ ipm ent. I f two
different supplies are used, they should be independently powered.
1.5 OMS 870 Installation
Use the following procedures to install The OMS 870 in an
equipment rack, verify that at least 3 RU of space is available.
When installing the OMS 870, you can also use the extension
brackets, included in the OMS 870 accessory kit, to convert a 485mm (19-inch) rack to a 600-mm (23.6-inch) rack.
TIP! 1 RU is 44.45 mm.
Caution!
Wear a grounding wrist strap while unpacking,handling and
interconnecting the OMS 870 equipment modules, to discharge
any static buildup.

1.5.1 Mount in a 19” rack
Decide which side do you want to use as the front side. You can use
the side with the connectors or the Ericsson branded side as the
front side if you have rear access.See Figure 2 and Figure 3
Figure 2 Ericsson branded side of the OMS 870
Figure 3 Connector side of OMS 870
PROCEDURE: MOUNT THE OMS 870 IN A 19” RACK
1. Remove the two phillips screws on the left and right and install
the brackets with longer phillips screws that are also in the plastic
bag.
2. Move the OMS 870 to the desired rack position
3. Align four M6 cage nuts in the equipment rack with the mounting
holes on the front of the OMS 870.
4. Align the OMS 870 with the equipment rack and cage nuts.
5. Insert the OMS 870 into the equipment rack.
6. Connect the OMS 870 to the equipment rack with four M6
screws.
1.5.2 Mount in a 600 mm rack with ETSI brackets
The shelf assembly is also possible to install in a 600-mm (23.6-in.)
rack, for this installation you can use extension brackets. You will
need two 1 RU extension brackets for this procedure.

Decide which side do you want to use as the front side (you can use
the side with the connectors or the Ericsson branded side as the
front side) depends on if you have back access
1. Remove the two phillips screws on the left and right and install
the extension brackets with longer phillips screws that are also in
the plastic bag.
2. Follow step 2-6 in “Mount in a 19” rack” on page 1-9.
1.5.3 Installation in Restricted Access Location (RAL)
The OMS 870 can be installed in a restricted access location (RAL)
or outside of an RAL.
After installation in a RAL, such as in a telecommunication centre,
the OMS 870 must be properly installed in a rack with b racket s or in
other ways properly connected to a safety ground.
The OMS 870 48V DC must not be powered from a source external
to the RAL. All communication interfaces used must be limited to
SELV. E1 interface used should be limited to SELV.
1.5.3.1 Installation outside a Restricted Access Location
After installation, the OMS 870 48V power and all communication
ports used must be connected to SELV circuits, for example a port
on a personal computer or 10/100 Mbit Ethernet hub/router or other
Information Technology (IT) equipment.
The 48V DC power must not exceed 60 VDC and must be powered
from an certified external power supply unit (PSU) or a battery unit
(no connection to -48 V telecom voltage).
The optical ports (if present) have no limitations regarding safety
recommendations.
1.5.3.2 Definitions
Restricted Access Location (RAL)
A location for equipment where both of the following paragraphs
apply:
• Access can only be gained by service persons or by users who
have been instructed about the reasons for the restrictions
