Power Supply Modules
Switches in this series can either be AC powered or DC powered depending on the power supply modules used. After
the initial purchase of a switch in this series, at least one power supply module will be included in the package. This
power supply can either be one of the following:
AC Power Supply Modules
AC-0460W-12-FB: AC Power Supply (Front-to-Back Airflow), 100 VAC to 240 VAC, 460 Watt.
AC-0460W-12-BF: AC Power Supply (Back-to-Front Airflow), 100 VAC to 240 VAC, 460 Watt.

In addition to the main power supply module, a secondary optional power supply module can be acquired and
plugged into the second power supply module slot. The secondary power supply module will act as the backup for the
primary power supply if the primary power connection fails. The switch from primary to secondary will take place
immediately and automatically.
Note: An AC power supply module cannot be used together with a DC power supply module to provide
redundancy. The primary and secondary power supplies must both be either AC supplied or DC
supplied, depending on the power supply module inserted.
The power supply modules are hot-swappable, meaning, that they can be inserted and removed while the switch is
powered on. This feature enhances the reliability of this switch. However, in the event that a power failure might occur
in the environment and no UPS is used, as a precaution, unplug the power cord from the switch. After the return of
power, you can plug the power cord back into the switch’s power connector.
Note: Never leave an open power supply module slot open, without a cover panel, as this will negate the
airflow within the switch.
Fan Modules
Switches in this series are powerful computing devices that require consistent airflow that is unobstructed. One of the
well-thought design aspects of switches in this series is that airflow can be channeled either from the front of the
switch to the back of the switch (front-to-back airflow) or from the back of the switch to the front of the switch
(back-to-front airflow). When airflow is properly channeled, the internal temperature of the switch will remain in the
safe zone, improving the reliability of the components used in the switch.
Warning: As a precaution, install the switch in a fairly cool and dry place within the acceptable
temperature and humidity operating ranges.
After the initial purchase of a switch in this series, at least 4 fan modules will be included in the package. These fan
modules must support the same airflow direction and can either be one of the following:
Fan Modules
FAN-17000-FB: Fan Module (Front-to-Back Airflow).
FAN-17000-BF: Fan Module (Back-to-Front Airflow).
In addition to the 4 main fan modules, an optional 5th fan module can be acquired and plugged into the 5th fan
module slot.
The fan modules are also hot-swappable, meaning, that they can be inserted and removed while the switch is powered
on. This feature enhances the reliability of this switch.
Note: The fan modules’ airflow direction and the power supply modules’ airflow direction must be
identical to maximize air circulation through the switch.
Note: Never leave an open fan module slot open, without a cover panel, as this will negate the airflow
within the switch.
Side Panel Components
The side panels of switches in this series feature 6 frontal rack-mount bracket screw holes and 10 rack-mount slider
bracket pegs on each side. Frontal rack-mount brackets can be attached to the side panels, where screw holes are
provided.

Hardware Installation
Installation Guidelines
This section will discuss the hardware installation guidelines that administrators must follow in order to properly and
safely install this switch into the appropriate environment.
Note: Please read through the Safety Instructions chapter before starting any installation discussed in
this chapter.
Installation using the Rubber Feet
When installing the switch in an area other than inside a switch rack, like on a desktop, rubber feet can be attached to
the bottom panel of the switch. On the bottom panel of the switch, there are clearly marked squares where the rubber
feet can be attached. These marked squares are usually found close to the corners of the switch’s bottom panel.
Adhesive material is included on the rubber feet. Simply pull away the protective sticker, of each rubber foot and then
attach the foot into the appropriately marked square. The rubber feet cushion the switch, protecting the casing from
scratches and preventing it from scratching other surfaces.
Figure 5-1 Installation using the rubber feet
Install the switch on a sturdy, level surface that can support the weight of the switch. Do not place any heavy objects
on the switch. Make sure that there is proper heat dissipation from and adequate ventilation around the switch. Leave
at least 10 cm (4 inches) of space at the front and rear of the switch for ventilation.
Installation into a Rack
Normally, ToR switches are installed not only into a rack-mount unit but at the top of the rack. The switch can be
mounted in a standard 19"(1U) rack using the provided mounting brackets. The following section will explain how to
install the rack-mount brackets onto the switch and then mount the switch into a standard 1U rack-mount unit.
The following parts will be used to install the switch into a rack-mount unit:
One pair of frontal rack-mount brackets.
One pair of rack-mount slider brackets.

SNQ-60x0-320F Series Data Center Switch Hardware Installation Guide

Note: Make sure that there is adequate space around the switch to allow for proper air flow, ventilation,
and cooling.
Installing Transceivers into the Transceiver Ports
Switches in this series have 32 QSFP+ ports. QSFP+ technology allows a smooth transition from 10 to 40 Gigabit
Ethernet infrastructures in data centers. Each of the switch’s QSFP+ ports can operate in either the native 40 Gigabit
Ethernet mode or the 4 times 10 Gigabit Ethernet mode. This switch supports both fiber and copper cabling solutions
for these two modes.
For low-cost cabling, copper-based 40 Gbps Twinaxial cables can be used, and for longer cable reaches, Short-Reach
(SR) optical transceivers are excellent. Connectivity can be established from the QSFP+ ports to 10 Gigabit Ethernet
switches or hosts using a splitter cable that has a QSFP+ transceiver on one end and four SFP+ transceivers on the
other end. Similar capability can be achieved on the fiber solution by using QSFP+ SR4 transceivers on both ends and
procuring third-party fiber splitter MPO-to-LC cables.

Installing Power Modules into the Power Module Slots
Switches in this series can have 2 redundant power supplies installed. When the one power supply fails, the second
power supply will automatically take over the power supply responsibilities until the faulty power supply has been
replaced.
Installing an AC Power Supply Module
This section will assist administrators with the installation and replacement of AC power supply modules in this switch.
On the back panel of the switch, there are two power supply module slots.
The figure below illustrates how to properly install an AC power supply module.
1. It is important to make sure which airflow direction is used in this switch. Have a look at the fan modules
installed and make sure that the AC power supply module supports the same airflow direction. The airflow
direction can either be front-to-back or back-to-front airflow.
2. Remove the power supply module slot’s protective cover by simply pulling the lever attach to it. The cover
should come off without any difficulty.
3. Insert the AC power supply module, without an AC power cord supplying power, into the power supply
module slot. Make sure that the AC power supply module is inserted all the way until the clip clicks into place.
4. Connect one end of the AC power cord, included in the package, into the grounded electrical outlet at the site
and insert the other end of the AC power cord into the AC power port of the AC power supply module. The
switch will automatically adjust the voltage supplied to the voltage needed as this power supply supports any
voltage power supply in the range from 100VAC to 240VAC at 50Hz to 60Hz.
Figure 5-7 Installing an AC Power Supply Module (Before)
Note: By default, only one power supply module is installed in the second power supply module slot. The
open power supply module slot will be covered with a panel. When purchasing a second power
supply module, make sure that the airflow of the new power supply module functions in the same
direction as the existing power supply module. Never leave an open power supply module slot
open, without a cover panel, as this will negate the airflow within the switch.
