2.2 Product Description - Magnum 1000-series Workgroup Hubs

Magnum 1000 Workgroup Hubs are full-featured 10BASE-T Ethernet hubs.

Magnum 1000 Hubs provide a low cost, flexible solution for networking a small workgroup or for adding additional nodes to an existing network via twisted pair cabling. Magnum 1000 Hubs are well suited for small- to medium-size facilities requiring an independent Ethernet network, and will operate as self-sufficient devices to provide 10BASE-T Ethernet connectivity for all local users and devices. Small independent networks built using Magnum 1000 Hubs are easily expanded by cascading, adding hubs of the same or similar types to grow the network.

4


The family of Magnum 1000 Workgroup Hubs is comprised of Models 1008

(pronounced “ten oh-eight”), 1016 (“ten sixteen”) and 1024 (“ten twenty-four”). These models are equipped with 8, 16 or 24 front-mounted, shielded RJ-45 ports, respectively.

Magnum 1000 Workgroup Hubs support full Ethernet segment lengths and operate in compliance with the IEEE 802.3 specification for repeater functionality to perform signal amplification, re-timing, and regeneration of preamble bits for each packet received. Consistent with IEEE 802.3 specifications, Magnum 1000 Hubs will detect collisions, generate jam signals, extend collision fragments, and automatically partition and re-connect individual ports.

For models with optional 48V DC power supply built in, see Appendix B.

2.2.1 Magnum 1008 Workgroup Hub

The Magnum 1008 Workgroup Hub, shown in Figure 2.2.1a, has eight frontmounted, shielded RJ-45 ports and one rear-mounted AUI port. The left-most RJ-45 port (port 1) is equipped with a slide switch to allow cascading or an up-link without a crossover cable. Refer to section 3.3.1 for details about the up-link switch.

Figure 2.2.1a: Front view - Magnum 1008 Workgroup Hub

Status LEDs are located on the front panel of the Magnum 1008 for convenient monitoring of PWR, ACT (Activity) and LINK (per port). Magnum 1008s have an auto-ranging internal power supply, and are suitable for table-top-, wall-, or rack-mounting. Optional rack-mount brackets may be ordered, part number 1008-RMB.

Figure 2.2.1b shows the rear-mounted AUI port. This is the base or default configuration for the Magnum 1008. The basic AUI (standard female) port may be used for a direct connection with an AUI drop cable or for connection to any media type via an external mini-transceiver.

When using standard AUI cabling to connect to other Ethernet devices, it is important to consider the AUI segment length, including any cascading. Refer to

Section 3.3.2 for detailed information on the AUI port, connector pins and standard cable length requirements.

AC Power

115 - 230 VAC Basic AUI Port

Figure 2.2.1b: Rear view - Magnum 1008 Workgroup Hub with the basic AUI port

As an alternative to the basic AUI port, it is possible (at the time of initial order) to replace the basic AUI rear port with any Magnum Port Module (PM). (See

Figure 2.2.1c). This option gives the Magnum 1008 great flexibility to easily conform to any standard Ethernet media environment. When configured with a Repeater Port

Module (RPM), the rear port can be used for direct connection to any standard Ethernet media. With a Bridge Port Module (BPM), the rear port is used to bridge-isolate the

Magnum 1008 from the rest of the network, increasing bandwidth for both the local users and the rest of the network. Refer to Section 2.4 for Magnum Port Module information. (NOTE: The Magnum 1008’s basic AUI port is NOT an RPM-AUI, it is simply an AUI port without any

LEDs).

Bonus Port Configuration Options - RPMs and BPMs

Magnum 1000 Workgroup Hubs may be configured with any Repeater Port

Module (RPM) or Bridge Port Module (BPM) in the rear bonus port. (For the 1008, this is done by exchanging the basic AUI port for a Port Module). An RPM may be used to provide connectivity, such as to a backbone, via any standard Ethernet media. A BPM may be used to provide local-bridge isolation for the 1000 Workgroup Hub’s users.

RPMs are available for the following six Ethernet connector types: BNC

(ThinNet or 10BASE2), AUI (10BASE5 or ThickNet, DB-15 female for most transceiver connections), DTE (DB-15 male-AUI for direct connects), ST (Ethernet multi-mode Fiber ST), SMF (Ethernet single-mode Fiber), and RJ-45 (10BASE-T UTP and STP). They are shown in Figure 2.4a.

2.4.1

RPM-BNC

The Magnum RPM-BNC repeater module is equipped with a standard

10BASE2 coax connector. This RPM performs full IEEE 802.3 repeater functionality and is used for 10BASE2 ThinNet (commonly referred to as BNC) connections.

The RPM-BNC module is designed with a special switch-selectable internal termination function that eliminates the need for a "tee" connector and a 50 ohm terminator. To take advantage of internal termination, the slide switch should be in the

"DOWN" (or right-side) position. In this configuration, the 10BASE2 segment is directly attached to the BNC port where it is internally terminated. When the switch is in the "UP" (or left-side) position, the BNC port requires a "tee" connector

require a "tee" connector, used as a tap, to allow the 10BASE2 coax segment to continue on past the RPM-BNC connection.

Magnum BPM-BNC

The RPM-BNC module includes one partition (PART) and one receive (RX)

LED, which are visible from the exterior. (The PART LED is inoperative on Model

1000 Hubs because the logic necessary to drive the LED is not included in the design.)

The RX LED illuminates GREEN intermittently to indicate data is being received.

Important Note: for the RPM-BNC Termination Switch -

DOWN (or right): Internally Terminated

This module is equipped with a 15 pin female AUI connector and a slide-lock, and performs full IEEE 802.3 repeater functionality. It is used to provide connectivity with a 10BASE5 (ThickNet) backbone or to any AUI segments. A transceiver is required when connecting to a ThickNet segment and the RPM-AUI supports this convention.

The RPM-AUI is also a "universal" Ethernet media interface as it may be

11


used with a variety of different mini-transceivers to provide connectivity to any media type.

The RPM-AUI card is equipped with Partition (PART) and Receive (RX)

LEDs. The RX LED functions the same as the RX LEDs of the RPM-BNC. The PART

LED is inoperative on Model 1000 Workgroup Hubs. (Section 2.4.1 above).

The Magnum RPM-AUI card is also used for connecting

Ethernet devices using standard

AUI cabling. In this situation, it is important to consider the AUI segment length or distance to the

As an additional indicator, a multi-mode TX port emits light (red in color) that is in the visible spectrum and which can be seen by looking into the port with the power on and with no cable connected. The single-mode TX port emits light outside of the visible spectrum and will always look dark to the human eye.

Note: Be sure to use single-mode fiber optic cable with this module (see Section 3.8.9).

Single-mode fiber cable has a smaller diameter than multi-mode fiber cable (2/15 - 8/60 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode, where xx/xx are the diameters of the core and the core plus the cladding respectively).

NOTE: The RPM-SMF circuit board contains a six-pins (three positions) jumper, but the jumper is only to be placed across pins 5 & 6 for single-mode. The other jumper positions are not used for single-mode fiber.

With the switch in the UP position, the RPM-TP port is used for up-link connections (i.e.: a connection to another repeater or hub typically.) When used for segments going to workstations and other user device connections, the switch should be in the DOWN position. Proper switch position can be verified by noting that the port’s

LINK LED will illuminate when proper link is established.

The RPM-TP will support 10BASE-T unshielded twisted pair wiring (UTP) environments with maximum segment distances up to 100m (325 ft.), or shielded twisted pair wiring (STP) of 150m (500 ft.). This module is designed with internal transceiver functionality. The RPM-TP has LINK, PART (inoperative on Model 1000

Hubs), and RX LEDs.

Special Option -- Second Bonus Port (Models 1016 and 1024)

In special cases, it may be desirable to configure the Magnum 1016 or 1024

Workgroup Hub with a second Port Module. The 1016 and 1024 Workgroup Hubs were designed to accommodate such a configuration, and the second Bonus Port may be configured by a trained technician and connected into header J1-RPM. In order to install a second PM, it is necessary to replace the factory-installed Basic AUI Port, connected into header J1, with the desired Port Module. This procedure requires a Port

Module connector cable (ordered separately as part number PM-CBL, or equal), and is similar that of the Model 1008 change from a Basic AUI to a PM. Request special quote for factory installation of a second Port Module for Models 1016 and 1024.

NOTE: LEDs of the 2nd PM (connected in J1-RPM) may not be functional.

NOTE: Due to the Bridge Port Module functionality, only one BPM may be configured per Workgroup Hub.

INSTALLATION

This section gives instructions for installing the Magnum 1000 Workgroup

Hubs, and for connecting the various Ethernet media.

3.1

Table-Top or Rack-Mount

Installation of a Magnum 1000 Workgroup Hub is a very simple procedure.

Magnum hubs are easily mounted in a rack or on a table-top. When properly installed, the front-mounted LED status indicators should be in plain view and easy to read.

Rack mounting installation requires a special rack-mount

3.2

Powering the Magnum 1000 Workgroup Hub

Magnum 1000 Workgroup Hubs incorporate an internal universal power supply, and have a recessed male IEC connector for the AC power cord at the right-rear.

A six-foot 115 VAC 60 Hz power cord is supplied with each unit shipped within the

United states and Canada.

Each Magnum 1000 Workgroup Hub’s auto-ranging power supply supports installation environments where the AC voltage is from 90 to 260 volts with a power input frequency between 47 and 63 Hz, and will consume a maximum of 20 watts

(estimated). In order to power down the unit, simply unplug either end of the power cable.

When connecting various Ethernet media, there is no need to power down the unit. Individual segments of any media type can be connected or disconnected without concern for AC power-related problems or damage to the unit.

22


3.3

Ethernet Media Connections

The Magnum 1000 workgroup Hub may be used as a stand-alone hub serving the needs of a small to medium size workgroup or may be connected to a larger network environment. In either case, user connectivity is achieved using twisted pair wiring,

Cat. 3 or Cat 5, UTP or STP. There may be some cases where a user device will be connected via the AUI or Bonus Port.

In applications where Magnum hubs are used to provide workgroup services within a larger network system, the rear port(s) may be connected into a larger network, rather than being used to connect to a user.

The various media types supported and their corresponding IEEE 802.3

standards and connector types are as follows:

Instructions for connecting the Magnum 1000 Workgroup Hub to each of the standard Ethernet types are given below.

3.3.1

Connecting Twisted Pair (RJ-45, Unshielded or Shielded)

The following procedure describes how to connect a 10BASE-T twisted pair segment to the RJ-45 port on the front panel of the hub or to the RPM-TP or BPM-TP.

The procedure is the same for both unshielded and shielded twisted pair segments.

1. Using standard 10BASE-T media, insert either end of the cable with an RJ-45 plug into the RJ-45 connector. Note that, even though the TP connector is shielded, either unshielded or shielded 10BASE-T cables and wiring may be used.

2. Connect the other end of the cable to the corresponding device.

3. When proper connection and power have been established, the port’s LINK LED will illuminate GREEN.

23


NOTE: Port 1 of the Magnum 1000 Workgroup Hub (and the Magnum RPM-TP and

BPM-TP) are equipped with a cross-over slide switch to accommodate repeater-to-repeater connections without special cross-over connectors.

Set the slide switch to the “left” (for port 1) or “down” (for PM-TP) position for normal twisted pair cable segments from the hub port to a user device. Set the slide switch to the “right” (port 1) or “up” (for PM-TP) position for cascaded or up-link segment connections to another repeater or hub in the network. Verify proper switch position by noting that the port’s LINK LED will illuminate when proper link is established.

3.3.2 Connecting ThickNet 10BASE5 (AUI)

Using the steps below as a guide, attach a new or existing 10BASE5 ThickNet drop-cable directly to the AUI connector on the rear of the Magnum 1000 Workgroup

Hub or on the RPM-AUI or BPM-AUI port.

1. Plug the male end of the cable into the female AUI connector on the Magnum

1000 or PM-AUI card.

2. Engage the AUI connector slide lock to insure maximum connectivity.

3. Connect the opposite end of the cable into a network AUI port. (This could be a network backbone transceiver, a hub or fan-out with an AUI port, or an AUI Port Module in a concentrator.)

The AUI port may also used for connecting to other Ethernet devices using standard AUI cabling. In this type of situation, it is important to consider the AUI segment length to the attached device, including any cascading.

The maximum transmission distance between a backbone transceiver equipped with an AUI connector and the AUI port of the Magnum 1000 will vary.

According to Ethernet standards, when an AUI cable is used to connect the Magnum

1000 directly to a backbone transceiver, the maximum AUI segment length of 50m (165 ft.) is allowed. If the Magnum 1000 is connected to a transceiver that has been cascaded from another transceiver, the maximum AUI segment length is reduced as stated below.

Important Note: The maximum transmission distance is decreased by 6m

(20 ft.) for every additional level of network transceiver device "dropped" or "cascaded" from the original backbone transceiver tap.

The RPM-AUI connector supports standard IEEE signals, which are summarized in Table 3.3.2.

3.3.3

Connecting ThinNet 10BASE2 (BNC)

Connect the ThinNet coax cable to the BNC connector on the Magnum RPM-

BNC or BPM-BNC card in the same manner as is done for any standard BNC connection. The PM-BNC port is specially equipped with an internal termination switch on the front of the card (see Section 4.1 for a description of this switch). This eliminates the need to use a "tee" connector when the BNC cable is ending at the connection to this

PM. Some applications may require a "tee" connector, used as a tap, to allow the

10BASE2 coax segment to continue on past the PM-BNC connection.

3.3.4 Connecting Drop Cable 10BASE5 (DTE)

Using the steps below as a guide, attach the 10BASE5 drop-cable directly to the

DTE connector on the RPM-DTE port.

1. Plug the female end of the cable into the male DTE connector on the RPM-DTE card.

2. Engage the AUI connector slide lock (on the cable) to insure maximum connectivity.

3. Connect the opposite end of the cable into a network AUI port. (This could be a server, router, bridge, hub, or UNIX workstation.)

3.3.5 Connecting Fiber Optic 10BASE-FL and FOIRL (ST-type, “Twist-Lock")

The following procedure applies to FOIRL and 10BASE-FL applications using an RPM-ST or BPM-ST card with ST-type fiber connectors. (The primary difference between FOIRL and 10BASE-FL for users is the maximum distance allowed. 10BASE-

FL is used for a fiber segment length of up to 2000m, while FOIRL is used for fiber segments of up to 1000m in length.)

1.

Before connecting the fiber optic cable, remove the protective dust caps from the tips of the connectors on the PM-ST. Save these dust caps for future use.

25


2.

Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue dampened in alcohol. Make certain the connectors are clean before connecting.

Note: One strand of the duplex fiber optic cable is coded using color bands at regular intervals; you must use the color-coded strand on the associated ports at each end of the fiber optic segment.

3.

Connect the Transmit (TX) port (light colored post) on the Magnum PM-FST to the Receive (RX) port of the remote device. Begin with the color-coded strand of the cable for this first TX-to-RX connection.

4.

Connect the Receive (RX) port (dark colored post) on the PM-FST to the

Transmit (TX) port of the remote device. Use the non-color coded fiber strand for this.

5.

The LINK LED on the front of the PM-FST will illuminate when a proper connection has been established at both ends (and when power is ON in the unit). If LINK is not lit after cable connection, the normal cause is improper cable polarity. Swap the fiber cables at the Port Module connector to remedy this situation.

3.3.6

Connecting Fiber Optic (SMA-type, "Screw-on")*

The same five-step procedure as for fiber ST-type applies to FOIRL and

10BASE-FL applications using an RPM-SMA card used with SMA-type fiber connectors. Follow the five steps as described in the Section 3.3.5 above.

When connecting fiber media to SMA connectors, do not over-tighten but rather simply "finger tighten" these connections. Do not use a heavy tool (such as a wrench) to tighten the fiber optic connectors as this might cause damage and result in operating problems. Improper and excessive tightening may impair data transmission.

* The RPM-SMA is only available via special order.

3.3.7

Connecting Single-Mode Fiber Optic (SMF)

When using the RPM-SMF, be sure to use single-mode fiber cable. Singlemode fiber cable has a smaller diameter than multi-mode Fiber cable (2/15 - 8/60 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx are the diameters of the core and the core plus the cladding respectively). Because of this, single-mode fiber allows full bandwidth at longer distances, and may be used to connect nodes up to 10 Km apart. For operation with standard half-duplex Ethernet, collision domain and / or power budget limitations may apply for distances over 5Km. Check your single-mode configuration with an experienced network designer when you use extended distances.

The same five-step procedure for multi-mode fiber ST-type applies to singlemode fiber connectors. Follow the five steps listed in Section 3.3.5 above.

Media

Power Budget Calculations for Magnum 1000 Series RPM’s with Fiber

Receiver Sensitivity and Transmitter Power are the parameters necessary to compute the power budget. To calculate the power budget of different fiber media installations using Magnum products, the following equations should be used:

OPB (Optical Power Budget) = P

T

(min) - P

R

(min)

where P

T

= Transmitter Output Power, and P

R

= Receiver Sensitivity

Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)

Worst case distance = {Worst case OPB, in dB} / [Cable Loss, in dB/Km] where the “Cable Loss” for 62.5/125 and 50/125 µm (M.m) is 2.8 dB/km, and the “Cable Loss” for 100/140 (Multi-mode) is 3.3 dB/km, and the “Cable Loss” for 9/125 (Single-mode) is 0.5 dB/km

The following data has been collected from component manufacturer’s (HP’s and

Siemens’) web sites and catalogs to provide guidance to network designers and installers.

* Note: The use of either multi-mode or single-mode fiber to operate at 100Mbps speed over long distances (i.e., in excess of approx. 400 meters) can be achieved

only

if the following factors are both applied:

•

The 100Mb fiber segment must operate in full-duplex (FDX) mode, i.e. the full-duplex (factory default) setting for 100Mbps fiber ports must be used, and

•

The worst-case OPB of the fiber link must be greater than the fiber cable’s passive Attenuation.

(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor)

OPERATION

The Magnum 1000 Workgroup Hubs operate as full-function Ethernet repeaters. They are compliant with IEEE 802.3 specifications for CSMA/CD 10 Mbps operation, and support standard IEEE defined media inclusive of 10BASE-T, 10BASE-

FL, FOIRL, 10BASE2, and 10BASE5. The following describes the basic functionality.

4.1

Magnum 1000 Repeater Functionality

Repeater Functionality: Each hub port operates in conjunction with the controller functions of the Magnum 1000 Hub’s base unit, functioning together as a fully compliant Ethernet repeater.

28


Collisions: When carrier is detected simultaneously on multiple ports, a jam pattern is generated on each port to create a collision condition. When a collision signal from one port is detected, it generates a jam pattern to the other ports.

Partitioning and Re-Connection: Magnum 1000 Hubs will automatically partition any port where 32 consecutive collisions occur or after 6.5 milliseconds (msec) of continuous transmissions. Network integrity is checked every 800 msec and segment re-connection occurs after one 512-bit packet is transmitted without an error.

Fragment Extension: Magnum 1000 Hubs will automatically add bits to a received data packet of less than 96 bits (a "fragment") so that the minimum output packet to the other port is 96 bits long.

Preamble Regeneration: Magnum 1000 Hubs will add bits to the preamble so that the output packet contains a minimum of a 64-bit preamble.

Status LEDs: Each Magnum 1000 Workgroup Hub is designed with front panel LEDs to allow for quick visual assessment of the operational condition of the hub and the network. Each Magnum 1000 Hub is equipped with PWR, ACT, and LINK

LEDs. Bonus Port RPMs are also equipped with status LEDs (see Section 2.4).

PWR LED: Illuminates GREEN to indicate proper operation of the internal power supply.

ACT LED: Illuminates GREEN to indicate “activity”, i.e., that the hub is processing network packets. Normally flashes to indicate data traffic.

LINK LEDs: Illuminates GREEN when connectivity is established between the hub and the attached device. Each RJ-45 port is represented by its own LINK LED. LINK should always be on during normal operation. LINK is OFF if connectivity or power is lost anywhere along the segment.

29


4.2

Magnum 1000’s with BPM Local Bridge Functionality

When configured with a BPM, a Magnum 1000 Workgroup Hub and its attached devices are bridge-isolated from the network segment connected through the

BPM. The bridge functionality of the BPM bridge modules is described here.

1. Bridge Functions: Each BPM card contains a compact local bridge module which filters and forwards packets at full Ethernet wire speed. These micro-bridges are self learning and have small (256 user) address tables.

Packet filter/forward decisions are made based on whether the packet source is internal (originates within the local Magnum 1000) or external (originates from upstream on the attached segment). If the packet’s source is internal, it is forwarded to the outside only if the destination address is not in the address table. Figure 4.2a shows

Internal packets are forwarded when the destination is

NOT IN the address table.

FWD-X LED “ON”

an internal packet being forwarded to the external segment.

Figure 4.2a: Internal

Packet Forwarded

Figure 4.2b show the cases where an internal packet is filtered. When the packet’s source is external, it is forwarded to the inside only if the destination address is in the address table.

Internal packets are filtered when the destination is

IN the address table.

The filter/forward

handling of external packets are shown in figures 4.2c and

4.2d respectively. When an internal packet’s source address is not already in the address table, it is written

there. This happens when a node first sends

Figure 4.2c: External Packet

Forwarded

a packet upon bridge initialization.

Note, therefore, that the address table learns only internal addresses, i.e., those connected via the inside of the local

Magnum 1000, a number typically well under the 256 table addresses size. Should the table become full, the BPM will clear all entries in the table by reinitializing itself.

When

an external packet’s source address is in the address table, it is purged.

Figure 4.2d: External Packet Filtered

This can occur if a node has physically moved to a different location.

2. Throughput Increase: By using a BPM to isolate a user group segment having significant local traffic, it is possible to increase overall network throughput. For example, a segment containing a group of workstations and servers may have heavy local traffic, but only a small amount of traffic that is

31


directed outside the segment. A BPM connecting this segment to the rest of the network, as shown in Figure 4.2e, will keep the local segment traffic isolated from the rest of the network, thus increasing the effective bandwidth on both the local segment and the rest of the network.

Local nodes with heavy local traffic, connected to front RJ-45 ports


Local segment isolation through Bonus Port configured with BPM (BPM-FST shown)

Figure 4.2e: Local Segment Isolation with a Bridge Port Module (BPM)

3. Bridge Transparency: The BPMs are transparent to both the users and the application software.

4. LINK and Traffic Status: The Magnum BPM-TP and BPM-FST indicate link integrity with an LED. This LINK LED is normally lit. An unlit

LINK LED indicates a broken cable or loss of power at some point in the segment. All BPMs have FWD-I and FWD-X status LEDs. The FWD-I LED flashes when packets are forwarded into the local segment. The FWD-X LED flashes when packets are forwarded out of the local segment.

5. Self-test Diagnostics: A Magnum BPM requires 15 seconds upon powerup before bridging services are available. During this time, the BPM performs an internal self-test.

APPLICATIONS

Magnum 1000 Workgroup Hubs are easily installed in a variety of applications where -48VDC, 24VDC & 125VDC power is used as the primary power source. The -48VDC, 24VDC & 125VDC power configuration provides an Ethernet networking solution utilizing a special DC internal power supply in hubs having a proven reliability record.

The solution is particularly useful in the telecommunication industry, where it is common for facilities to operate on -48VDC power. Such companies include regular and wireless telephone service providers, Internet Service Providers (ISPs), other communication companies, and firms supplying network management and operations monitoring equipment. In addition, many high-availability equipment services, such as in broadcasters, publishers, heavy industrial plants, brokerage firms and others, often use a battery backup system to maintain operations in the event of a power failure.

The 24VDC & 125VDC solution are particularly useful in the

Industrial environment, where it is common facilities to operate on 24VDC & 125VDC power. The 125VDC solution is mainly used in Utilities Industries, such as Electric substation, Electrical generating plant etc. Whereas 24VDC application is mainly in the

Industrial environment, such as chemical plants, paper mill, stone quarrying plant, wastewater treatment Plant etc

Simply connect the DC leads to the Switch’s power terminals, positive (+) and negative (-) screws. The use of Ground (GND) is optional; it connects to the Switch chassis. Ensure that each lead is securely tightened.

37


Note: Before connecting to Terminal Block of –48VDC, 24VDC or 125VDC, always use a digital voltmeter to measure the output voltage of the power supply and determine the lead which is more “+ve potential Lead”. The more “+ve” voltage terminal lead from 48V or –48V Power supply must be connected to the post labeled

“+”.

The GND can be hooked at the last.

Disconnecting the DC power source is used to remove the unit from service, and as a power-down to RESET the hub’s electronics if needed.

B4.1 UL Requirements

1. Minimum 14 AWG cable for connection to a Centralized DC power source.

2. Fastening torque of the lugs on the terminal block: 9 inch pound max.
