2 Hardware Description
The NSH-5632 is a high-performance managed SNMP Layer 3 switch that provides
users with 24 x 100Mbps Fast Ethernet and 4 Gigabit Combo ports. The Web/SNMP
management provides remote control capability that gives user-friendly and flexible
network management and monitoring options.
For increased bandwidth applications, the NSH-5632 provides 2 trunk groups of 2
member (Combo) ports per trunk or one group of four (Combo) ports
Moreover, these trunk ports ship with fair-over function to provide redundant back-up if
one or more of the ports are malfunctioning. It also supports both Port-based VLAN and
Tag-based VLAN, thereby simplifying network traffic segmentation, broadcast domain
extension and other associated benefits of constructing VLANs. This abundance of
features translates into increased efficiency and performance in network administration.
The Switch was especially developed with a host of features that make it particularly
suited for FTTx applications which demand the utmost in reliability. The device comes
with 24 100Base-TX/FX SFP ports and 4 SFP gigabit fiber ports that are each
interchangeable with 4 additional Gigabit Ethernet ports. The package provides
100Base-TX/FX SFP and Gigabit fiber conversion. Thus, the Gigabit fiber and copper
ports provide flexible, high-bandwidth and fast uplinks, while the 100TX/FX SFP ports
offer flexibility in network configurations.
Being SNMP-ready, the Switch enables network managers to remotely monitor the
entire network status quickly and easily via switch ports (in-band), or console port (out-
of-band) connection. This managed Switch can extend the enterprise LAN configuration
range up to 110km while simultaneously minimizing the troubleshooting time. The Switch
is designed for 'plug-n-play' to enable hassle-free integration in today's managed mixed
cabling network configurations.
Featuring auto MDI/MDI-X （10/100/1000 copper ports ）detection for direct
connections to a workstation, switch or hub, network managers no longer need to worry
about the cable configuration (crossover or straight through) when establishing
connections between RJ-45 ports.
The Switch has auto-negotiation capabilities that allow it to support connection with
leading NWay switches. In full-duplex mode, this unit can sustain distances of up to
550m (with multi-mode fiber) and 110km (with long-haul single-mode fiber) between a
LAN switch and another switch or data/file server.

VOLKTEK NSH-5632 MANAGED 24-SLOT 100BASE-TX/FX SFP + 4 G COMBO L3 SWITCH
2.2 Connectors
The Switch utilizes ports with copper and fiber port connectors functioning under
Ethernet/Fast Ethernet/Gigabit Ethernet standards.
2.2.1 100Base-TX/FX SFP Ports
The 100BASE-TX/FX SFP ports support network speeds of 100Mbps, and can operate
in half-duplex or full-duplex transfer modes. The following are recommended cabling for
the RJ-45 connectors: 100Mbps – Cat 5 or better.
2.2.2 10/100/1000Base-T Ports
The Switch has four Gigabit 10/100/1000Base-T ports for RJ-45 connectors that have
the same features as the above-mentioned. The only difference is that the Gigabit
copper ports support network speeds of 10/100/1000Mbps.
These four ports are located next to the four SFP-type fiber slots and each one of these
RJ-45 ports is interchangeable with a corresponding SFP slot. The Gigabit copper port
will have the same number as its corresponding SFP slot. This means that once an SFP
slot is connected, the correspondingly numbered RJ-45 port (25, 26, 27 or 28) will not
function.
2.2.3 Combo SFP slots for SFP modules
The four SFP slots are designed to house Gigabit SFP modules that support network
speeds of 1000Mbps. These slots are interchangeable with the four 1000Base-T ports to
their left and the slots have the same port numbers as their corresponding 1000Base-T
ports. This means that once an SFP slot is connected via an SFP module, the
correspondingly numbered 1000Base-T port (25, 26, 27 or 28) will not function.

3 Installation
The location chosen for installing the Switch may greatly affect its performance. When
selecting a site, we recommend considering the following rules:
•Install the Switch in an appropriate place. See Technical Specifications for the
acceptable temperature and humidity ranges.
•Install the Switch in a location that is not affected by strong electromagnetic field
generators (such as motors), vibration, dust, and direct sunlight.
•Leave at least 10cm of space at the front and rear of the unit for ventilation.
•Affix the provided rubber pads to the bottom of the Switch to protect the case
from scratching.
3.1 Desktop installation
Follow the instructions listed below to install the Switch in a desktop location.
1. Locate the Switch in a clean, flat and safe position that has convenient access to
AC power.
2. Affix the four (4) self-adhesive rubber pads to the underside of the Switch.
3. Apply AC power to the Switch (The green PWR LED on the front panel should
light up).
4. Connect cables from the network partner devices to the ports on the front panel
(The green LNK LED on the front panel associated with the port should light).
This Switch can also be mounted on a vertical surface. Simply use the
underside of the unit as a template to measure and mark out the position of the
holes on to the surface where the unit is to be installed. Then use the two
screws provided to mount the Switch firmly in place.
Warning: Because invisible laser radiation may be emitted from the aperture of the
port when no cable is connected, avoid exposure to laser radiation and do not stare
into open apertures.
3.2 Mounting on a rack
Attach brackets to each side of the switch and place the brackets in the rack’s slots.
Insert and tighten two screws to securely attach the bracket to the rack on each side.
3.3 Getting Connected

11

VOLKTEK NSH-5632 MANAGED 24-SLOT 100BASE-TX/FX SFP + 4 G COMBO L3 SWITCH
3.4 Powering On the Unit
The Switch uses an AC power supply 100~240V AC, 50~60 Hz, or DC -48V. The power
on/off switch is located at the rear of the unit, adjacent to the AC power connector and
the system fans. The Switch’s power supply automatically self-adjusts to the local power
source and may be powered on without having any or all LAN segment cables
connected.
1. Insert the power cable plug directly into the receptacle located at the back of the
device.
2. Plug the power adapter into an available socket.
Note: For international use, you may need to change the AC power adapter
cord. You must use a power cord set that has been approved for the
receptacle type and electrical current in your country.
3. Check the front-panel LEDs as the device is powered on to verify that the
Power LED is lit. If not, check that the power cable is correctly and securely
plugged in.
3.5 Installing the SFP modules and Fiber Cable
1) The NSH-5632 has 4 Gigabit SFP slots:
2) Slide the selected SFP module into the selected SFP slot. (Make sure the SFP
module is aligned correctly with the inside of the slot):
3) Insert and slide the module into the SFP slot until it clicks into place:
4) Remove any rubber plugs that may be present in the SFP module’s mouth.
5) Align the fiber cable’s connector with the SFP module’s mouth and insert the
connector:
6) Slide the connector in until a click is heard:
7) If you want to pull the connector out, first push down the release clip on top of the
connector to release the connector from the SFP module.
To properly connect fiber cabling: Check that the fiber terminators are clean. You can
clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened
with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of
the light transmitted through the cable and lead to degraded performance on the port.
Note: When inserting the cable, be sure the tab on the plug clicks into
position to ensure that it is properly seated.
Check the corresponding port LED on the Switch to be sure that the connection is valid.

5.3 Configuring the Switch via Console Port (RS-232 DCE)
Prior to accessing the switch’s onboard agent via a network connection, you must first
configure it by giving it a valid IP address, subnet mask, and default gateway, using an
out-of-band connection or the BOOTP protocol.
After configuring the Switch’s IP parameters, you can access the onboard configuration
program from anywhere within the attached network or via internet. The onboard
configuration program can be accessed by using Telnet from any computer attached to
the network. It can also be managed with any computer using a Web browser (Internet
Explorer 4.0 or above, or Netscape Navigator 4.0 or above).
Access the Switch via a terminal emulator (such as Hyper Terminal) attached to the
console port. The console port is set at the factory with the following default COM port
properties. Configure your own terminal to match the following:
•Baud rate: 38,400
•Data size: 8bits
•Parity: None
•Stop bits: 1
•Flow Control: None
NOTE: Ensure that the terminal or PC you are using to make this connection is
configured to match the above settings. Otherwise the connection will not work.
A console port cable is provided with the Switch to connect the PC’s COM port with the
Switch’s serial console port.
5.3.1 Using HyperTerminal to Set IP address
Prior to following the instructions listed below for HyperTerminal, verify that a
console cable (RJ45 to DB9) connection between the Switch and workstation exists.
Then follow the steps below:

1. Launch the terminal emulation program on the remote workstation and power on
the Switch. Be sure to select the correct COM port.
2. Enter the correct parameters according to the defaults given on the previous
page:
3. The prompt screen will appear after selecting “OK”. The default log-in name is
“admin” with no preset password (just press <ENTER>).
4. The prompt Switch> will appear. For a list of main commands, type “?” and
<Enter>. For a list of sub-commands, type a main command like “list” and <Enter>:

After successful log-in, type the following command line to change the device IP,
Network Mask, and Gateway address:
Switch#config terminal
Switch(config)#interface vlan1
Switch(config-if)#ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx
Switch(config-if)#exit
Switch(config)#ip route 0.0.0.0/0 xxx.xxx.xxx.xxx
The xxx’s represent values between 0 and 255 and the user should enter their own IP
address in this form. The configuration program will not accept anything outside this
format. Remember to separate each part of the address with a period (dot).
When the address has been changed, please make a note of the new address, and
keep it in a safe place. With HyperTerminal, the command lines are the same as that for
telnet. Users can continue to use Hyper Terminal along with the instructions given in
next sections. Otherwise, log out by typing ‘exit’ and pressing the <ENTER>key. Then,
the user can choose to configure the Switch via HTTP Web Browser or Telnet with Menu
Driven or Command Line interfaces.
Note: IP addresses are unique. If an address isn’t available, please contact the
appropriate authorities to apply for one.
5.4 Telnet and SSH
Activate your workstation’s command prompt program (like Putty) and access your
Switch via the Internet by typing in the correct IP address (factory default IP address is
192.168.0.254 – connect directly via console port to configure a unique IP address). A
command prompt program like Putty will give you the option of choosing either Telnet or
SSH (Secure Shared) protocol. SSH is an encrypted protocol and is ideal for ISP
workers who have to be extra careful when managing their switches.
Figure underneath: Screenshot of Putty program where IP address is typed in and Telnet or SSH is
selected:

After opening the program, a command prompt screen will appear. At the Switch login
line, type the pre-set password – the factory default is admin. Type ‘?’ for a list of main
commands. On the screenshot below, the writer had typed the list command below the
last listed main command.

5.5 SNMP Settings
Simple Network Management Protocol (SNMP) is an Application Layer designed
specifically for managing and monitoring network devices. SNMP enables network
management stations to read and modify the settings of gateways, routers, switches,
and other network devices. Use SNMP to configure system features for proper operation,
monitor performance and detect potential problems in the Switch, switch group or
network. Managed devices that support SNMP include software (referred to as an agent),
which runs locally on the device. A defined set of variables (managed objects) is
maintained by the SNMP agent and used to manage the device. These objects are
defined in a Management Information Base (MIB), which provides a standard
presentation of the information controlled by the on-board SNMP agent. SNMP defines
both the format of the MIB specifications and the protocol used to access this
information over the network.
5.6 Traps
Traps are messages that alert network personnel of events that occur on the Switch.
The events can be as serious as a reboot (someone accidentally turned OFF the Switch),
or less serious like a port status change. The Switch generates traps and sends them to
the trap recipient (or network manager). Typical traps include trap messages for
Authentication Failure, Topology Change and Broadcast\Multicast Storm.
5.7 MIBs
The Switch in the Management Information Base (MIB) stores management and counter
information. The Switch uses the standard MIB-II Management Information Base module.
Consequently, values for MIB objects can be retrieved from any SNMP-based network
management software. MIB values can be either read-only or read-and-write.
