1 Overview
Providing 400GbE fabric ports, the S9705-48D enables the disaggregated architecture required
to fulll the high trac loading in a 5G mobile Ethernet network. As part of USpace’s S9700
Series, the S9705-48D is a robust, exible and carrier-grade router that is coupled with the
S9700-53DX and/or S9700-23D routers for small/medium or large clusters. Suitable for core
networking, the S9705-48D adopts service and fabric routers building blocks to provide carriers
with a beer soluon in place of the tradional chassis
With 1+1 redundancy hot-swappable PSU FRU, 3+1 redundancy hot-swappable Fan FRU,
and a high port density design, the S9705-48D delivers high system reliability, Ethernet
switching performance and intelligence to the network that helps reduce infrastructure and
administrave costs.
This document describes the hardware installaon process for S9705-48D.

It is recommended that switch installaon be done by two individuals. One individual
should hold the switch in posion on the rack, while the other secures it in place using
the rail slide screws.

6 InstallingtheFanModules
The fan module is a hot swappable eld replaceable unit, which can be replaced while the switch is
operang as long as the remaining three modules are installed and in operaon. The fans come pre-
installed and the following steps are instrucons on how to install a new fan module:
1. Press and hold the release tab located on the fan module inward to unlock the old fan
module from the fan bay.
2. While holding down the red tab, grip the handle located on the fan module and gently pull
the old fan module out of the fan bay.
3. Align the new fan module with the fan bay, ensuring that the fan module’s power connector
is in the correct posion.
4. Carefully slide the new fan module into the fan bay and gently push unl it is ush with the
switch case.
5. An audible click will be heard when the fan module is installed correctly. The fan module
will not go in all the way if it is installed in the wrong direcon.

7 InstallingthePowerSupplyUnits
The power supply unit (PSU) is a hot swappable eld replaceable unit and can be replaced
while the switch is operang as long as the remaining (second) PSU is installed and in operaon
(with 220V power input). The AC and DC PSU follow the same steps for installaon. The PSU
comes pre-installed and the following are instrucons on how to install a new PSU.
Warning
If power input for AC power supply is only 110V, there will only be 1000 was per power
supply and will not be enough power for the power supply to be changed while the
switch is in operaon. In order for AC power supply to be changed while the switch is in
operaon, ensure that 220V power is supplied.
Caution
Shock hazard!
Disconnect all power inputs before servicing.

8 GroundingtheSwitch
It is recommended that the switch changes be installed on a ground compliant rack system.
This will reduce or prevent the risk of shock hazards, equipment damage, and potenal of data
corrupon.
The switch can be grounded from the switch chassis and/or the DC power supply units (PSUs).
When grounding the DC PSUs, ensure that both PSUs are grounded at the same me in case
one of them is removed. The grounding wire is not provided with the switch package contents.
M4 screws and washers are provided with the switch package contents
Warning
This equipment must be grounded. Do not defeat the ground conductor or operate
the equipment without a suitably installed ground conductor. Contact the appropriate
electrical inspecon authority or an electrician if you are uncertain about whether your
equipment has been correctly grounded.
The following instrucons are for grounding the switch chassis:
1. Before grounding the switch chassis, ensure that the rack is properly grounded and in
compliance with local regulatory guidelines, ensure that a good electrical connecon to the
grounding point exists, and remove any paint or materials that may prevent good grounding
contact.
2. Strip the insulaon from a size #6 AWG ground wire (not provided), leaving 0.5” +/-0.02”
(12.7mm +/-0.5mm) of exposed grounding wire.
3. Insert the exposed grounding wire all the way into the hole of the ground lug (provided with
switch package contents).
4. Using a crimping tool, rmly secure the grounding wire to the ground lug.

S9705-48D Hardware Installaon Guide | 14
5. Remove yellow tape located on the switch chassis that is covering the holes for securing the
ground lug.
6. Using 2 M4 screws and 4 washers (provided with switch package contents), rmly lock the
ground lug to the switch chassis. ground lug to the switch chassis.

9 ConnecngPower
9.1 SystemPowerConsumpon
The maximum power consumpon of the S9705-48D is 1466 was. It is recommended
that enough power be reserved from the power distribuon system in order to support the
proper funcon of the S9705-48D. Ensure that both PSUs have been properly installed before
powering up the switch, as the S9705-48D is designed to support 1 + 1 power redundancy
9.2 ConnecngtheACVersionPSU
9.2.1 AachingtheACPowerCord
Locate the AC inlet connector on the PSU and plug the AC power cable (250Vac 15A,
IEC60320 C19) into the AC inlet connector.
9.2.2 FeedingACPower
The PSU will immediately output 12V & 5VSB to the system with a 220V, AC power source.
The PSU has a built-in 15 amperes, fast acng fuse based on the PSU maximum capacity,
which will act as a second er system protecon in case the power distribuon unit’s fuse is
not funconing.
Note
If only a 110V AC power source is available, the S9705-48D can sll be powered with
both PSUs providing 1000 was each for a total output of 2000 was. However, in this
case, if one PSU stops funconing, the power output would be inecient to sustain the
switch’s operaon.
9.3 ConnecngtheDCVersionPSU
9.3.1 BeforeAachingtheDCPowerCable
The UL 1015, 6 AWG DC power cable (not provided) must be aached to a two-hole lug
before connecng to the PSU. The following instrucons are for connecng the DC Power
Cable to the lug:
1. Strip the insulaon from a DC Power Cable, leaving 0.5” +/-0.02” (12.7mm +/-0.5mm) of
exposed cable.
2. Insert the exposed DC power cable into the heat shrink tubing, the length of heat shrink
tubing should not less than 38.5mm.
3. Insert the exposed DC power cable all the way into the hollow tube of the lug (provided
with switch package contents).
4. Using a crimping tool, rmly secure the DC power cable to the lug. It is recommended to
not crimp exceeding the lines indicated on the lug, which is also depicted as the cross-
secon area in the picture on the below.

S9705-48D Hardware Installaon Guide | 16
5. Move the heat shrink tubing to cover any exposed metal on the DC power cable and lug.
6. Use a heat source to secure the heat shrink tubing in place. Allow the heat shrink tubing
to cool before aaching the DC power cable. An example of the installed DC version with
insulaon material as below.

S9705-48D Hardware Installaon Guide | 17
9.3.2 AachingtheDCPowerCable
Locate the DC power screw-type terminal block located on the PSU. Remove the plasc cover
that is protecng the terminal block by pushing from the top or boom of the cover and
ipping open the cover outwards (Top picture). Secure the two-hole lug (with the DC power
cable aached) to the terminal block (Middle picture). Put plasc cover back on terminal
block to guard against contact with terminals (Boom picture).
9.3.3 TighteningtheScrews
Tighten the screws to a torque value of 14.0+/-0.5kgf.cm. If the torque is not enough, the
lug will not be secure and may cause malfuncons. If the torque is too much, the terminal
block or lug may be damaged. The previous picture depicts how it should look once the lug is
aached and the protecve plasc cover reinstalled.
9.3.4 8.3.4.FeedingDCPower
The PSU will immediately output 12V and 5VSB to the system with a -48V DC power source.
The PSU has a built in 80 amperes, fast acng fuse based on the PSU maximum capacity,
which will act as a second er system protecon in case the power distribuon unit’s fuse is
not funconing.
