This document provides simple and distinctive guidelines for quick hardware installation of the PTN 910E-F.
This document does not describe pre-delivery assembly, but only describes procedures for onsite installation.
The PTN 910E-F supports indoor installation. Ensure that requirements on device operating environments are met before
installation. Using the outdoor cabinet IMB network box can moderately improve the device operating environment. If you need to
use an outdoor cabinet other than the IMB network box for the PTN 910E-F, contact Huawei to determine whether the outdoor
cabinet meets requirements of Huawei devices on the device operating environments.
Pre-Installation Check
Before installation, check whether the installation environment and accessories meet installation
requirements. Refer to the Installation Guide for information about specific operational requirements and
technical specifications.
NOTE
CAUTION
CAUTION
Laser beams from optical fibers may harm your eyes. Do not look into the optical interfaces without
eye protection when performing operations such as installing and maintaining optical fibers.

Common Requirements for Installing, Laying out, and
Bundling Cables
The space between power cables, network cables, and optical fibers must be greater than 30 mm.
Power cables, network cables, and optical fibers cannot be interleaved but must be routed in parallel or separated with specific stuffs.
When cables are fixed or bound, the interval between two cable ties cannot exceed 40 cm.
When cables are bent, the bending radius is recommended to be greater than 60 mm and cables are not bundled at the turning
points.
The bending radius of optical fibers is no less than 40 mm. Do not pull, press, or squeeze optical fibers during installation.
Gently coil excess optical fibers. Do not forcibly bend the optical fibers.
Do not power on the device when installing and laying out cables.

When installing or maintaining optical fibers, do not look into the optical port without eye protection. See
Figure 1.
When laying out optical fibers, take proper measures to avoid any damage to fiber connectors.
After optical fibers are installed, place protective caps on the idle optical interfaces and place fiber caps on
the idle optical fibers. See Figure 2.
The type of the fiber connector is LC/PC.

CAUTION
Wrap both ends of the corrugated pipe using tapes to prevent optical fibers from being cut.
Do not use an open-end corrugated pipe to
hold excessive optical fibers. It is
recommended that an open-end
corrugated pipe that has a diameter of 32
mm accommodates 60 optical fibers at
most, each with a diameter of 2 mm.
Ensure that about 10 cm of the open-end
corrugated pipe is inside the cabinet.

You can also use the method of looping back Ethernet interfaces ( applicable to the Ethernet interfaces on
a device that is powered on ) to check the connectivity of network cables. That is, connect two Ethernet
interfaces using the network cable to be tested. If the LINK indicator is on, the network cable is normal.

Installation Checklist
NO. Check Item
1 The chassis is positioned in the proper place as prescribed by the engineering design specific to the site.
When the chassis is installed in a 19-inch rack, ensure that the chassis does not come into contact with
the front door and cables are not pressed against the front door when the front door is closed.
2 Each chassis component does not have any paint drop, damage, or stain. Otherwise, re-paint or clean
the component.
3 After a card is installed on the chassis, tighten the screws on the front panel of the card.
4 Install filler panels in idle slots on the chassis.
5 Cables are laid out according to the engineering design, facilitating maintenance and expansion.
6 Cables are not damaged or broken, and there is no joint on the cables.
7 Each core wire of the cables must be tested for connectivity.
8 Cables are bundled properly with equal space between cable ties. The cable ties must be neat, and must
not have sharp edges. Cut the extra parts on cable ties.
9 Signal cables are correctly routed inside a cabinet.
10 Lay out cables outside the cabinet based on the following requirements:
•Cables are laid out neatly without crossing.
•If a cable ladder is used, fasten the cables neatly on the beam of the cable ladder. If the distance
between the cable tray and the cabinet top is greater than 0.8 m, install the cable ladder at the top of the
cable tray to reduce the stress generated by the weight of the cables.
11 Cables are bent smoothly and have a large bending radius.
12 Labels attached to both ends of signal cables are correctly written, securely attached 2 cm away from
connectors, and neatly placed in the same direction.
13 Power and ground cables are laid out separately from signal cables.
14 Protective caps are placed on unused cable connectors for protection.
15 The length of the protection tube of fiber patch cords in the cabinet is about 10 cm, and the tube must be
bound securely.
16 The cut end of the protection tube of fiber patch cords is smooth and without sharp edges. If the cut end
is not smooth, wrap it using insulation tape.
17 The tail fibers should not be bound over-tightly, and can be moved freely in the cable tie.
18 The connection points of tail fibers are clean and dustless. Unused optical fiber headers and blade optical
ports are protected by protective caps or protective plugs.

Powering on the Device
aChecking the voltage and the fuse capacity of the external power supply
bChecking the power-on status
Before the device is powered on, you must use the multimeter to test whether a short-circuit occurs between
the positive and negative terminals of the PDU.
Standard Voltage of the Input Power Supply ( DC ) Allowed Voltage Range ( DC )
-48 V - 38.4 V to - 57.6 V
-60 V - 48 V to - 72 V
The power
output is faulty.
It is recommended that one circuit breaker ( fuse ) in the end of suite ( EoS ) corresponds to one device
( subrack ). That is, one circuit breaker in the EoS outputs one channel of power supply, which is provided to
only one device instead of multiple devices. If one circuit breaker in the EoS corresponds to multiple devices and
the overcurrent fault occurs on a device, the circuit breaker may perform the protection operation. As a result,
multiple devices are powered off.
Maximum Working Current Recommended Fuse Capacity
3 A ≥ 5 A
1Checking the Device Before Powering on it
NOTE
For details about how to check the indicator status when AC power supply is used, see the
corresponding description when DC power supply is used.

RST button.
Blink every 200 ms ( green ) The database is being erased by setting the RST
button.
Blink every 500 ms ( green ) The software of the board is initialized.
Red 1. A hardware fault occurs on the board. 2. The database fails to be erased by setting the
RST button.
Off 1. The board is not working.
2. The board is not powered on.

To check the connectivity of an optical fiber, you need to check the deviation of the optical power between an optical
interface on the card and the peer interface on the ODF. If the optical power meter reads a value less than or equal to 1 dB,
the connectivity of the optical fiber is correct. Otherwise, check the optical fiber.
If the tail fiber is connected through a flange during the check process, the deviation should be less than 2 dB.
When an optical power meter is used during a test, it is recommended that you record the actual transmit optical power of
each optical interface and check whether the transmit optical power is normal.
Consult the project supervisor or software engineer and determine whether it is necessary to test the receive optical power
using an optical power meter to check whether the receive optical power is normal.
