Pre-Installation Considerations
Gigabit Considerations:
If you will use the switch for Gigabit applications, keep in mind that the
maximum UTP cabling length of Category 5e cable is 328 feet (100 meters).
Positioning the switch:
When choosing a location for the switch, observe the following guidelines:
Keep enough ventilation space between the switch and the surrounding
objects.
Keep cabling away from sources of electrical noise, power lines, and
fluorescent lighting fixtures.
Do not stack free-standing switch more than four units high. One other way to
deploy multiple NP2724M’s is by using a star network topology and connect.
Desktop or Shelf Mounting
To install the switch on a desktop or shelf, simply complete the following steps:
Step 1
Place the switch on a desktop or shelf near an AC power source.
Step 2
NP2724M User Manual 5
Keep enough ventilation space between the switch and the surrounding
objects.
Note:
When choosing a location, keep in mind the environmental restrictions
discussed in Chapter 4, Specifications.
Step 3
Connect the switch to network devices.
A. Connect one end of a standard network cable to the RJ-45 ports on the
front of the switch.
B. Connect the other end of the cable to the network devices such as printer
servers, workstations or routers.
Note: It is recommended to use the UTP Category 5e network cabling with
RJ-45 tips for the network connection. For more information, please see the
Cable Specifications in Chapter 4, Specifications.
Step 4
Supply power to the switch.
A. Connect one end of the power cable to the switch.
B. Connect the power cube end of the power cable to a standard wall outlet.
2.6. Rack- Mount Placement
Before mounting the Switch, please read the following instructions carefully,
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is
not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven mechanical
loading.
D) Circuit Overloading - Consideration should be given to the connection of
the equipment to the supply circuit and the effect that overloading of the
circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections
NP2724M User Manual 6
other than direct connections to the branch circuit (e.g. use of power
strips)."
To mount the Switch in any standard-sized, 19-inch wide, 1U high rack,
please follow these instructions:
Place the Switch on a hard flat surface with the front panel facing you. Attach
a rack–mount bracket to one side of the Switch with the supplied screws.
Then attach the other bracket to the other side. (Figure 2.6.1)

2.7. Preparing for configuration
NP2724M offers a console CLI interface for switch configuration and web
management. Users can use this interface to perform device configuration.
There are four methods to manage your switch:
Local Console Management
You can manage the NP2724M switch locally by connecting the switch to a
PC or workstation with terminal emulation software using the serial port.
Remote Console Management
You can manage the switch by having a remote host establish a Telnet
connection to the switch via an Ethernet or modem link.
SNMP Management
You can manage the switch across a LAN using an SNMP Network
Management Station with a graphical user interface. Note that to use this
management method, your network must use the IP protocol and your switch
must be configured on the Network with a proper IP address.
NP2724M User Manual 8
Web-Browser
