Connecting SBC 5000 Series Ethernet and Data Cables

This section provides information on connecting media (packet) ports, HA ports, management ports, serial port and alarms ports and installing SFPs.

Installing SFPs

The following SFP transceivers are compatible with SBC 5000 series in all Media and HA ports:

• SBC-5XXX-SFPSM: GIG-E, SINGLE MODE, FIBER OPTIC TRANSCEIVER MODULE, LC, SMALL FORM PLUGGABLE (SFP), 10KM 1310NM, DMI
• SBC-5XXX-SFPMM: GIG-E, MULTI-MODE, FIBER OPTIC TRANSCEIVER MODULE, LC, SMALL FORM PLUGGABLE (SFP), 300M
• SBC-5XXX-SFPCOPPER: GIG-E, 1000 BASE-T SMALL FORM PLUGGABLE (SFP)

SFP transceivers must be installed in the Media and HA (if configured for HA) ports of each SBC 5000 series server before making the fiber/copper connections.

• Insert the SFP Gigabit Ethernet LC or SFP Gigabit Ethernet copper RJ-45 transceivers into SBC 5100/5110 media ports 0-1, SBC 5200/5210 media ports 0-3, as needed.
• Insert the SFP Gigabit Ethernet LC or SFP Gigabit Ethernet copper RJ-45 transceivers into HA ports 0-1, as needed.

Follow these steps to install SFPs for the first time. To replace an SFP, see the CRU document SBC 5000 Series SFPs.

1. Attach an Electrostatic Discharge (ESD) wrist strap (provided in the SBC 5000 series kit) using the ESD grounding point on the rear panel of the chassis (see Connecting Electrostatic Discharge Wrist Strap).
2. Insert the Ribbon-approved SFP transceiver into the desired socket and ensure that the proper orientation when inserting, and that you will hear a click-in when the SFP is seated correctly.
3. Connect/reconnect the fiber optic and/or CAT 5 cables, as appropriate, to media and HA ports.
4. Verify LEDs above the part are flashing indicating link status and data activity.
5. Verify port functionality using the CLI show status system commands once the SBC application software is installed and the system is up and running (for details, refer to Show Status System).

   1. Verify management and packet port functionality:

   2. Verify HA port functionality:

Connecting Serial Port

When connecting a serial cable to the rear serial port of the SBC server for communication with a host PC, refer to the figure below for the serial port location.

SBC Serial Port Connection

The following table lists the serial port settings for the host PC.

The DB9 serial cable pin-out is shown below.

Null Modem Serial Cable

Connecting Management Port

To establish the Management port connections, connect the CAT5e cable to the Mgmt 0 and Mgmt 1 ports. The CAT5e cable may be connected to a switch, router, LAN or WAN as per the customer requirements.

Connecting High Availability Ports

The physical connection between two SBC 5000 series systems consists of a pair of GigE cables (Use the Single mode or Multi mode fiber optic CAT5e cable (NON-CROSSOVER TYPE ONLY), directly connected between each HA ports.

The HA connections provides both box-Level and port-level redundancy system. The HA pair system consists of four management ports; two ports each per system. When a switchover occurs, the logical management address follows the currently active server. For the Media ports, the MAC and IP addresses float (are replicated from active to standby on fail-over).

Connecting Alarm Ports

The SBC 5000 series ports, allow you to sense (Alarm In) and issue (Alarm Out) external signal. The Alarm Port utilizes a DB15 pin connector and supports 4 output alarms and 2 input alarms. You must create the remainder of the cable, wiring the appropriate sensor or alarm leads to the screw terminator on the connector.

SBC 5000 Series Alarm Ports

The following table lists the Alarm port pin details and their descriptions.

Alarm Out Ports

Each Alarm Out port is a dry relay contact. Each contact will withstand up to 60 volts DC maximum when open, and will carry up to 1 ampere DC maximum when closed.

The following table lists the pin out for the Alarm Out port.

Alarm In Ports

Each Alarm In port is an isolated, current-sourcing sensor which expects to see an external dry contact connection open and close.

For proper operation, the total external load (wiring plus dry contacts) on an Alarm In port must be less than 200 ohms. (Each Alarm In port can source up to 20 milliamperes DC of current maximum, and withstand a voltage drop of up to 7.5 volts DC maximum across an external load.)

The following table lists the pin-out for the Alarm In port.
