1 INTRODUCTION OVERVIEW The ECS4810-12M is an intelligent Layer 2 switch designed for aggregating broadband traffic from the edge of a service provider’s (CO) network. It aggregates traffic using its 12 Gigabit combination RJ-45/SFP ports, (see Figure 2 on page 24).
CHAPTER 1 | Introduction Overview Figure 2: Front Panel Port Status Indicators AC Input DC Input Power Switch System Status Indicators Alarm Port Combination RJ45/SFP Ports RJ-45 Management Port and Console Port Figure 3: Side Panel Ventilation SWITCH ARCHITECTURE This switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports.
CHAPTER 1 | Introduction Network Management Options The switch uses store-and-forward switching to ensure maximum data integrity. With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network. NETWORK MANAGEMENT OPTIONS This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status.
CHAPTER 1 | Introduction Description of Hardware DESCRIPTION OF HARDWARE SFP SLOTS The 12 Small Form Factor Pluggable (SFP) transceiver slots are shared with 12 RJ-45 ports. In its default configuration, if an SFP transceiver (purchased separately) is installed in a slot and has a valid link on its port, the associated RJ-45 port is disabled and cannot be used. The switch can also be configured to force the use of an RJ-45 port or SFP slot, as required.
CHAPTER 1 | Introduction Description of Hardware Each port also supports auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated. 10/100/1000BASE-T MANAGEMENT PORT The 10/100/1000BASE-T port provides a dedicated management interface that is segregated from the data traffic crossing the other ports.
CHAPTER 1 | Introduction Description of Hardware PORT AND SYSTEM STATUS LEDS This switch includes a display panel for key system and port indications that simplifies installation and network troubleshooting. The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following tables.

To install an SFP transceiver, do the following: 1. Consider network and cabling requirements to select an appropriate SFP transceiver type. 2. Insert the transceiver with the optical connector facing outward and the slot connector facing down. Note that SFP transceivers are keyed so they can only be installed in one orientation.
CHAPTER 2 | Installing the Switch Connecting to a Power Source CONNECTING TO A POWER SOURCE This switch supports both AC and DC power supplies. CONNECTING DC POWER When using -48 VDC power, an external DC power supply must be connected to the DC power connector on the left side of the front panel. WARNING: Before wiring the DC plug or connecting power to the switch, ensure that power to the feed lines is turned off at the supply circuit breaker or disconnected from the power bus.
CHAPTER 2 | Installing the Switch Connecting to a Power Source 3. Use a wire stripper to carefully strip about a half an inch of the outer insulation off the end of each wire, exposing the copper core. 4. Twist the copper wire strands together to form a tight braid. If possible, solder the exposed braid of wire together for better conductivity. 5. Connect the external power feed and power ground/return lines to the DC plug (provided with the switch) as shown in the following figure.
CHAPTER 2 | Installing the Switch Connecting to a Power Source 10. Check the the PWR LED indicator as the switch is powered on. If the PWR LED is not on, recheck the power supply and power cable connections at the supply source and at power conversion module. CONNECTING AC POWER To connect the switch to an AC power source: 1. First verify that the external AC power supply can provide 100 to 240 VAC, 50-60 Hz, 0.65 A minimum. 2. Plug the power cable into a grounded, 3-pin, AC power source.
CHAPTER 2 | Installing the Switch Connecting to the Console Port 5. Check that the PWR LED indicator on the switch is on. If not, recheck the power supply and power cable connections at the supply source and at power module. CONNECTING TO THE CONSOLE PORT This port is used to connect a console device to the switch through a serial cable. The console device can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.

3 MAKING NETWORK CONNECTIONS CONNECTING NETWORK DEVICES This switch is designed to connect broadband access network devices to aggregation network devices in the service provider CO. It can connect to twisted-pair devices through its RJ-45 ports, or to fiber-optic devices through SFP transceivers. TWISTED-PAIR DEVICES Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T connections.
CHAPTER 3 | Making Network Connections Fiber Optic SFP Devices Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length. NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. 3.
CHAPTER 3 | Making Network Connections Fiber Optic SFP Devices 2. 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 cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port. 3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device.
CHAPTER 3 | Making Network Connections Connectivity Rules CONNECTIVITY RULES When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.
CHAPTER 3 | Making Network Connections Connectivity Rules Table 9: Maximum 1000BASE-ZX Gigabit Ethernet Cable Length Fiber Size Fiber Bandwidth Maximum Cable Length Connector 9/125 micron singlemode fiber N/A 70 km (43.
CHAPTER 3 | Making Network Connections Cable Labeling and Connection Records switch is connected to a hub, both devices must operate in half-duplex mode. 2. To interconnect distinct VLANs or IP subnets, you can attach the switch to a standard Layer 3 router. For network applications that require routing between dissimilar network types, attach the switch to a multi-protocol router. 3.
CHAPTER 3 | Making Network Connections Cable Labeling and Connection Records ◆ Note the length of each cable and the maximum cable length supported by the switch ports. ◆ For ease of understanding, use a location-based key when assigning prefixes to your cable labeling. ◆ Use sequential numbers for cables that originate from the same equipment. ◆ Differentiate between racks by naming accordingly. ◆ Label each separate piece of equipment.
