Switch Fabric Module (SFM and SFM2) Connectors and LEDs
The Switch Fabric Module (SFM or SFM2) sets up and tears down flow connections, monitors switch operation, and performs switch functions. The I/O modules use the SFM processors to perform routing functions, including resolution of unknown addresses, route determinations, protocol processing, and other exception events.
Each module provides 10-Gbps switch control element for switching functionality and flow processing for four I/O modules. You can install a second active module to service four additional I/O modules. Both active modules are on simultaneously in the CSS 11800. The chassis enables you to configure two additional passive modules for redundancy. Therefore, you can configure a total of four SFMs or SFM2s in a chassis, of which only two would be active at any time.
Note When the CSS 11800 contains two passive SFMs and an active SFM switchover occurs, both passive SFMs switchover to become active SFMs.
You can mix SFMs with SFM2s in the same CSS 11800 chassis. However, you must use the same type module as the active SFM and as the passive SFM.
The Switch Fabric Module (SFM and SFM2) contains Power, Status, and Active LEDs. The SFM has four RJ-45 RS-232 Console and Diag connectors (all of these connectors are reserved for field service diagnostic use only).
Figure 2-14 illustrates the SFM front panel LEDs and connectors.
Figure 2-14 Switch Fabric Module Connectors and LEDs
The SFM2 contains two RJ-45 RS-232 Diag1 and Diag 2 connectors, combining both Console and Diag functions on each connector (all of these connectors are reserved for field service diagnostic use only).
Note These connectors are for serial data only and are not compatible with Ethernet RJ-45 cable connectors.
Figure 2-15 illustrates the SFM2 (model CSS8-SFM2) front panel LEDs and connectors.

Connecting Power Cords
The CSS 11050 models are powered by an AC power supply. The CSS 11150 and CSS 11800 are powered by either an AC or DC power supply. Before you install the AC or DC power cord, ensure that you have read Appendix A, Specifications for electrical specifications. The following sections describe:
•Connecting a CSS 11050 or CSS 11150 Power Cord
•Connecting a CSS 11800 Power Cord
Connecting a CSS 11050 or CSS 11150 Power Cord
The following sections provide information on:
•Connecting a CSS 11050 or CSS 11150 AC Power Cord
•Connecting a CSS 11150 DC Power Cord
Note The CSS 11050 is only available in an AC version.
Connecting a CSS 11050 or CSS 11150 AC Power Cord
To connect an AC power cord to a CSS 11050 or CSS 11150:
1. Ensure that the CSS power switch is in the 0 (off) position.
2. Attach the power cord to the CSS by plugging the AC power cord connector into the power receptacle at the rear panel, as shown in Figure 2-17.
Figure 2-17 Connecting a CSS 11050 or CSS 11150 AC Power Cord
3. Plug the power cord into a dedicated 3-wire grounding receptacle.
4. Switch on the power on the CSS.
Connecting a CSS 11150 DC Power Cord
Before you install a DC power cord, see Appendix A, Specifications for DC power supply safety warnings.
Warning The DC power supply cord requires 18 AWG wire. The CSS 11150 draws a maximum of 25 amps.
Warning DC systems do not have a power switch. A chassis configured for DC power requires an external power disconnect device (such as an external circuit breaker).
Warning Before performing the DC installation procedure, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker that services the DC circuit and switch it off.
To connect the CSS 11150 DC power supply to a power source:
1. Locate the DC terminal block on the front of the chassis as shown in
Figure 2-18.
Figure 2-18 Location of CSS 11150 DC Power Supply Connectors
2. Using a flat-head screwdriver, loosen the captive screws on the three DC connectors (labeled from left to right, +, -, and
, respectively).
Warning Before installing a wire, ensure that the polarity of the DC connections is correct. Reversed polarity causes damage to the DC power supply and can create a dangerous shock hazard.
3. Install the wires into the appropriate connector. Make sure that the uninsulated part of each wire is 9mm (0.35 in.) in length.
When installing the wires, always connect the ground wire first. When disconnecting the wires, always disconnect the ground wire last.
The proper power cable wiring between the CSS 11150 and DC power source is illustrated in Table 2-10.

The following sections provide information for connecting an AC or DC power cord to a CSS 11800.
Note For information on installing a redundant AC or DC power supply, consult the reference sheet included with the power supply.
Connecting a CSS 11800 AC Power Cord
To connect an AC power cord to a CSS 11800:
1. Ensure that the CSS power switch is in the 0 (off) position.
2. Attach the power cord to the CSS by plugging the AC power cord connector into the power receptacle at the front of the chassis as shown in Figure 2-19.
Figure 2-19 Connecting a CSS 11800 AC Power Cord
3. Plug the power cord into a dedicated 3-wire grounding receptacle.
4. Switch on the power on the CSS.
Connecting a CSS 11800 DC Power Cord
Before you install a DC power cord, see Appendix A, Specifications for DC power supply safety warnings.
Warning The DC power supply cord requires 12 AWG wire. The CSS 11800 draws a maximum of 25 amps.
Warning DC systems do not have a power switch. A chassis configured for DC power requires an external power disconnect device (such as an external circuit breaker).
Warning Before performing the DC installation procedure, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker that services the DC circuit and switch it off.
To connect the CSS 11800 DC power supply to a power source:
1. Locate the DC terminal block on the front of the chassis as shown in
Figure 2-20.
Figure 2-20 Location of CSS 11800 DC Power Supply Connectors
2. Using a flat-head screwdriver, loosen the captive screws on the three DC connectors (labeled from left to right, +, -, and, respectively).
Warning Before installing a wire, ensure that the polarity of the DC connections is correct. Reversed polarity can cause damage to the DC power supply and can create a dangerous shock hazard.
3. Install the wires into the appropriate connector. Make sure that the uninsulated part of each wire is 9mm (0.35 in.) in length.
When installing the wires, always connect the ground wire first. When disconnecting the wires, always disconnect the ground wire last.
The proper power cable wiring between the CSS 11800 and DC power source is illustrated in Table 2-11.

4. Tighten the captive screws to 5 to 7 inch-pounds (.6 to .8 Nm) of torque to secure the wires in the connectors. Ensure the wires are held firmly in place.
Connecting the Console to the CSS
To connect a console to the CSS, attach the console cable (provided in the accessory kit) to the Console port on the CSS 11050 or CSS 11150 front panel, or to the CSS 11800 SCM panel. Your terminal settings must match the following CSS default settings:
•Baud Rate: 9600
•Data Bits: 8
•Flow Control: none
•Parity: none
•Stop Bits: 1
On the CSS 11050 or 11150 console cable, you must attach two snap-on ferrites provided in the Accessory kit. The ferrites guarantee proper console operation.
To attach the snap-on ferrites (see Figure 2-21):
1. Position and attach the first ferrite .75 inches from the RJ-45 connector to the Console port.
2. Attach the second ferrite behind the first ferrite.

Powering Up the CSS
To power up the AC on a CSS 11050, CSS 11150, or CSS 11800:
1. Attach the power cord to the CSS 11050 or CSS 11150 rear panel AC connector, or to the CSS 11800 AC connector (see the "Connecting Power Cords" section earlier in this chapter).
2. Power on the CSS by toggling the power switch to the 1 (on) position.
For DC power on a CSS 11150 or CSS 11800, set the external disconnect device to the 1 (on) position.
For information concerning the boot process on an 11000 series CSS, refer to the Content Services Switch Administration Guide. For general hardware troubleshooting information, see the following section.
Powering Down the CSS
To shutdown a CSS gracefully and avoid introducing lost or fragmented files, always use the shutdown command prior to removing power from the CSS. This command is available in boot mode.
For example:
Once the CSS shuts down all processes, you may remove power from the CSS.
Troubleshooting CSS Hardware Components
This section provides general troubleshooting information for the CSS components. It includes the following sections:
•Troubleshooting the Console Interface
•Troubleshooting the CSS Power Supply
•Troubleshooting the CSS 11800 Modules
Troubleshooting the Console Interface
Table 2-12 lists common communications problems that may exist between the CSS and a console. Ensure the console settings are configured to:
•Baud Rate - 9600
•Data Bits - 8
•Flow Control - none
•Parity - none
•Stop Bits -1
For information on console cable pinouts, see Appendix B, Cable Pinouts.
Table 2-12 Troubleshooting the Console Interface
Possible Problem
|
Recommended Action
|
Nothing appears on the screen.
|
Ensure the RS-232 cable is securely connected to the console port.
|
Characters appear on the screen, but are garbled.
|
Verify that the CSS and the console settings match for baud rate, data bits, stop bits, and parity.
|
Abbreviated input is used, but pressing the tab key does not enter the command you want.
|
Ensure that you enter enough characters for the CSS to distinguish between different commands and options.
|
Random characters are lost.
|
Set the flow command on the console to XON/XOFF.

Note Installing a second CSS 11800 power supply provides power load balancing between the two power supplies. When you install a second power supply, it powers on and begins to share the power load automatically.
Troubleshooting the CSS 11800 Modules
Each CSS 11800 module is equipped with a temperature sensor that detects an over- or under-temperature condition. If the module detects that its temperature is out of range, it generates a log message.
Module status is indicated by the Status LED on the module front panel. For information about the module LEDs, see the module information earlier in this chapter.
Table 2-15 provides suggestions for correcting problems that may occur with the modules.
Table 2-15 Troubleshooting the CSS 11800 Modules
Symptom
|
Recommended Action
|
System cannot identify module type.
|
Remove the module and re-install it to reseat the module in the backplane connector.
|
Reload the ADI file.
|
System cannot find an image for the module.
|
Reload the ADI file.
|
Module failed diagnostic (according to the information in the Boot.log file).
|
Replace the module.
|
You cannot access log or archive files on the CSS disk but traffic is still passed in and out of the CSS.
|
Replace the Internal Disk Module. Remove the module and re-install it to reseat the module in the backplane connector.
|
Replacement IDM does not initialize.
|
If the replacement IDM does not contain the same version of the software that the CSS is currently running, the SCM will not initialize the IDM for use. You must reboot the CSS and configure a primary boot record. You can select the CSS software currently on the disk or instruct the CSS where to locate the CSS software ADI file to install on the disk. If you archived an offline version of your CSS running-config file, copy it back onto the CSS.
