MST Impact NS5001, User Manual

Due to the difference in the fibre orientation, MST composite cable and fibre optic cable can only be
connected between ports on NS50 devices marked with a tick in the matrix below.

Single- and Multi-Mode Cables
The NS50 is supplied from the factory with 1000BASE-LX single-mode SFP modules. Customers wishing
to interface to other cable standards, e.g. 100BASE-FX single or multi-mode, should contact MST to
arrange replacement of the appropriate SFP modules.
Description SFP Part Number (MST Order Number)
Single-mode 100BASE-FX SFP module W-SFP-LS38-A3S
Multi-mode 100BASE-FX SFP module W-SFP-LM38-A3S
Note:
• If replacing the single-mode SFP modules with multi-mode modules, the single-mode patch
lead between the SFP module and the MST Composite Cable connector on the inside of the
housing needs to be replaced with a multi-mode patch lead.
• JB11 junction boxes can be connected inline between any two units in the chain to supply power.
There is no need to isolate NS50 units to a single power source.
Important: If an SFP is changed, the device must be rebooted or reset to detect the change.
1.3.2 Ethernet Ports
The NS50 has four external Ethernet ports, that enable connection to other networking devices.
The four Ethernet ports also provide IEEE 802.3af PoE (Power over Ethernet) injector functionality,
allowing a single cable to be used for data and power to network devices. Each Ethernet port's functionality
can be configured by the web browser interface, or by centralised configuration management. For more
information on configuring Ethernet ports, see
Configuring the VLAN Port Map on page 82.
1.3.3 Wireless Access
Wireless connectivity in each NS50 is implemented using a WAC (Wireless Access Card), consisting of
a wireless network processor and an integrated mini PCI 802.11b/g adapter.
A NS50 can contain up to two WACs. The WAC contained in the first radio card slot (on the left side)
also acts as the management CPU for the switch processor. As such, it is mandatory that this WAC is
fitted to each unit. The WAC operational parameters can be configured through the web browser interface
or by centralised configuration management. For more information, see
Configuring Wireless Radio on
page 68.
