This section provides information on connecting media (packet) ports, HA ports, management ports, serial port and alarms ports, and installing SFPs.
Installing SFPs
Ribbon-provided SFP modules must be used to guarantee proper operation of the external ports. Failure to follow this recommendation may cause permanent damage to the system.
1 Gb SFP Transceivers
The following 1 Gb SFP transceivers are compatible with SBC 5400 in all Media and HA ports:
| Order Code | Device Description | Pictures of Typical Device |
|---|---|---|
| SBC-SFPCOPPER-1G | GIG-E, 1000 BASE-T SMALL FROM PLUGGABLE (SFP) |  |
| SBC-SFPMM-1G | GIG-E, MULTIMODE, FIBER OPTIC TRANCEIVER MODULE, LC, SMALL FORM PLUGGABLE (SFP), 300M |  |
| SBC-SFPSM-1G | GIG-E, SINGLE MODE, FIBER OPTIC TRANSCEIVER MODULE, LC, SMALL FORM PLUGGABLE (SFP), 10KM 1310NM, DMI |  |
10 Gb SFP Transceivers
Optionally, Pkt0 and Pkt1 (Media 0 and Media 2) can be used as 10Gb ports using one of the in the table below, with the remaining MEDIA ports empty.
| Order Code | Device Description | Pictures of Typical Device |
|---|---|---|
SBC-SFPMM-10G | 10.3GB/S, MULTI-MODE, FIBER OPTIC XCVR, LC, SFP, 300M 850NM, DMI |  |
| SBC-SFPSM-10G | 10.3GB/S, SINGLE MODE, FIBER OPTIC XCVR, LC, SFP, 10KM 1310NM, DM |  |
SFP transceivers must be installed in the Media and HA (if configured for HA) ports of each SBC 5400 server before making the fiber/copper connections.
- Insert the SFP Gigabit Ethernet LC or SFP Gigabit Ethernet copper RJ-45 transceivers into SBC 5400 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.
The router(s) connected to the Media ports MUST support Gigabit speeds. Otherwise, the Gigabit Media ports will not be able to communicate with the router(s).
Follow these steps to install SFPs for the first time:
- Attach an Electrostatic Discharge (ESD) wrist strap (provided in the SBC 5400 kit) using the ESD grounding point on the rear panel of the chassis (refer to Connecting ESD Wrist Strap).
- Insert the Ribbon-approved SFP transceiver into the desired socket and ensure that the proper orientation when inserting, and you will hear a "click" sound when the SFP is latched correctly.
- Connect/reconnect the fiber optic and/or CAT 5 cables, as appropriate, to media and HA ports.
- Verify LEDs above the part are flashing that indicates link status and data activity.
- Verify port functionality using the CLI
show status systemcommands, once the SBC application software is installed and the system is up and running.Verify management and packet port functionality:
> show status system ethernetPort
Verify HA port functionality:
> show status system highAvailabilityPort
If an unsupported SFP module is inserted, an error message similar to the following displays:
PNPS: pkt1 SFP detected not supported by Ribbon! Turning pkt1 off!PNPS: Replace pkt1 SFP with an approved Ribbon part to ensure NEBS. Replace the SFP modules to resolve issue.
SFP Dust Plugs from the accessory kit may optionally be installed in any depopulated SFP socket.
Connecting Serial Port
For connecting a serial cable to the serial port to communicate with a host PC, refer to the serial port connection image.
The following table lists the serial port settings for the host PC.
Serial Port Settings | Value |
|---|---|
Baud | 38400 |
Data bits | 8 |
Stop bits | 1 |
Parity | None |
Flow Control | None |
The DB9 serial cable pin-out is shown below.
| Pin | Signal Type |
|---|---|
| 1 | DCD |
| 2 | RXD |
| 3 | TXD |
| 4 | DTR |
| 5 | GND |
| 6 | DSR |
| 7 | RTS |
| 8 | CTS |
| 9 | RI |
Null Modem Serial Cable
Connecting Management Port
To establish the Management port connections, connect the CAT5e cable to the Mgmt0, Mgmt1, Mgmt2, and Mgmt3 ports. The CAT5e cable may be connected to a switch, router, LAN or WAN.
Note
The SBC 5400 management ports are permanent. The management ports use standard RJ-45 copper Ethernet connectors and are standard 10/100/1000 Mb ports.
Tip
For connecting the switch ports to the management ports, Ribbon recommends the following:
- Enable the autonegotiation (or "autoneg") for both the connecting ports, to allow them to choose common transmission parameters, such as speed, duplex mode, and flow control.
- Set the advertised link modes to the following:
- 100 Mb Full Duplex, for SBC on hardware platforms.
- 1000 Mb Full Duplex, for SBC SWe.
Connecting High Availability Ports
The physical connection between two SBC 5400 systems consists of a pair of GIG-E 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 switchover).
Management and HA Port Connections for SBC 5400
If using fiber SFPs for HA connections, both ends of an HA connection must use the same type. Connecting a single mode SFP to a multi-mode will not work.
Connecting Alarm Ports
The Alarm port is not supported by the SBC 5400 application software in this release.
The SBC 5400 Alarm ports allow you to sense (Alarm In) and issue (Alarm Out) external signal. The Alarm Port utilizes a HD15 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 5400 Alarm Ports
The following table lists the Alarm port pin-out details and their descriptions.
Pin | Description |
|---|---|
1 | Minor Reset |
2 | Minor Reset Return |
3 | Major Reset |
4 | Major Reset Return |
5 | Critical Alarm Normally Open |
6 | Critical Alarm Normally Closed |
7 | Critical Alarm Return |
8 | Minor Alarm Return |
9 | Minor Alarm Normally Open |
10 | Minor Alarm Normally Closed |
11 | Major Alarm Normally Open |
12 | Major Alarm Normally Closed |
13 | Major Alarm Return |
14 | Power Alarm Normally Open |
15 | Power Alarm Return |
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.
| Pin | Signal | Power Out or Reset Condition |
|---|---|---|
| 1 | Alarm Out 1 | Closed |
| 2 | Alarm Out 1 Return | |
| 3 | Alarm Out 2 | Open |
| 4 | Alarm Out 2 Return | |
| 5 | Alarm Out 3 | Open |
| 6 | Alarm Out 3 Return | |
| 7 | Alarm Out 4 | Open |
| 8 | Alarm Out 4 Return |
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.
No external voltage or current should be applied to the Alarm In ports.
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.)
Pin 1 is beside the Alarm In text on the module face plate.
The following table lists the pin-out for the Alarm In port.
Pin | Signal | Power Out or Reset Condition |
|---|---|---|
1 | Alarm In 1 | |
2 | Alarm In 1 Return | |
3 | Alarm In 2 | |
4 | Alarm In 2 Return |
The ESD Susceptibility symbol 
warns of the presence of Ribbon devices susceptible to electrostatic discharge. Do not handle equipment without wearing a properly grounded ESD wrist strap.
