Rear Panel Description
The rear panel of the switch contains the following items:
AC power connector (100 to 240 VAC, 0 to 60 Hz)
Power cord retainer slot
SWITCH GND: grounding screw for attaching the terminal lug ring of the grounding
cable to the switch
Kensington-compatible security lock slot
MGMT port: used for connecting to a PC with standard Ethernet cable. This port
provides access to the switch through Telnet or Web browser. The MGMT port can
also be used to supply the switch with 90 W DC power using Power over HDBaseT.
This can be used as the main power source or as the secondary power source to
the switch.

Side Panel Description
The left-hand panel of the switch has heat vents to dissipate heat. Do not block these
openings, and leave at least 1 cm of space at the rear and sides of the switch for proper
ventilation. Be reminded that without proper heat dissipation and air circulation, system
components might overheat, which could lead to system failure. Also the left- and right-
hand panels of the switch have two fans and rack-mounting screw holes.

Switch Installation
This section will discuss the hardware installation guidelines that the user must follow in
order to properly and safely install this switch into the appropriate environment.
Visually inspect the power cord and see that it is fully secured to both the power
connector, on the Switch, and the electrical outlet that supplies power.
Install the Switch in a fairly cool and dry place within the acceptable operating
temperature and humidity ranges.
Install the Switch in a site free from strong electromagnetic field generators such as
motors, vibration, dust, and direct exposure to sunlight.

Installing the Switch without a Rack
This section is used to guide the user through installing the switch in an area other than a
switch rack. Attach the included rubber feet to the bottom of the switch. Take note that
there should be marked blocks on the bottom of the switch to indicate where to attach the
rubber feet. These markings are usually found in each corner on the bottom of the device.
The rubber feet cushion the switch, protecting the casing from scratches and preventing it
from scratching other surfaces.
Figure 4 — Attaching rubber feet to the switch
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 of space at the
front, sides, and rear of the switch for ventilation.
Installing the Switch in a Standard 19'' Rack
This section is used to guide the user through installing the switch into a switch rack. The
switch can be mounted in a standard 19"(1U) rack using the provided mounting brackets.
Fasten the mounting brackets to the sides of the switch using the screws provided.
Figure 5 — Attaching rack- ount brackets to the switch
Fasten the mounting brackets in any available open space in the rack using the screws
provided.

Installing Transceivers into the Transceiver Ports
The switch is equipped with Small Form-factor Pluggable (SFP) and Enhanced Small
Form-factor Pluggable (SFP+) ports that can be used to connect various other networking
devices to this switch that do not support the standard RJ-4 wiring connection. These
ports are generally used to connect this switch to optical fiber connections and can be
used to connect devices to the switch over great distances. The maximum distance that
the RJ-4 wiring connection can reach is 100 meters. Fiber optic connections can span
several kilometers.
Figure 7 — Inserting transceivers into the transceiver ports
Connecting AC Power to the Switch
Plug one end of the AC power cord into the power socket of the switch and the other end
into the local power source outlet.
;
Power Failure (AC Power)
In the event of a power failure, just as a precaution, unplug the power cord from the switch.
After the power returns, plug the power cord back into the power socket of the switch.
Installing the AC Power Cord Retainer
To prevent accidental removal of the AC power cord, it is recommended to install the
power cord retainer together with the power cord. With the rough side facing down, insert
the tie wrap into the hole below the power socket.
Figure 8 — Insert tie wrap into the switch
Plug the AC power cord into the power socket of the switch.
Figure 9 — Connect the power cord to the switch
Slide the retainer through the tie wrap until the end of the cord.
(
Figure 10 — Slide the retainer through the tie wrap
Circle the tie of the retainer around the power cord and into the locker of the retainer.
Figure 11 — Circle around the power cord
Fasten the tie of the retainer until the power cord is secured.
Figure 12 — Secure the power cord

Connecting PoH to the Switch
The MGMT port can be used to supply the switch with 90 W DC power using Power over
HDBaseT. This can be used as the main power source or as the secondary power source
to the switch.
CAUTION: Do not connect the RPS to AC power before the standard Ethernet cable
is connected. This might damage the internal power supply.
CAUTION: Leave at least 1 cm of space at the rear of the Switch when an RPS is
installed to prevent cable damage.
DPS-520 Redundant Power Supply
A standard Ethernet cable connects one of the four LAN ports on the DPS- 20 and the
PoH-capable MGMT port on the switch. A standard, three-pronged AC power cable
connects the redundant power supply to the main power source.
Figure 13 — Connecting the DPS-520 to the switch
Manage ent Options
This switch provides multiple access platforms that can be used to configure, manage, and
monitor networking features available on this switch. Currently there are three
management platforms available which are described below.
Co and Line Interface (CLI)
This switch can be managed, out-of-band, by using the console port or the MGMT port.
Alternatively, the switch can also be managed, in-band, by using a Telnet connection to
any of the LAN ports on the switch.
SNMP-based Manage ent
The switch can be managed with an SNMP-compatible console program. The switch
supports SNMPv1, SNMPv2c and SNMPv3.
