SRX3400 Services Gateway Switch Fabric Board

The Switch Fabric Board (SFB) is the data plane for the subsystems in the chassis. The SFB performs the following functions:

Table 8 describes the behavior of the Power button near the left end of the SFB front panel.

Table 8: Power Button Behavior

Condition

Action

Result

Device powered off

Short push (3 to 5 seconds)

Powers the device on. The PWR LED blinks to show you that the Routing Engine is initializing.

Device powered on

Short push (3 to 5 seconds)

Initiates a graceful shutdown that preserves the device state information. The PWR LED blinks to show you that the device is shutting down.

Long push (15 seconds or more)

Initiates an immediate shutdown. The device state information will be lost. Avoid using immediate shutdown unless necessary.

Table 9 describes the system behavior indicated by the various LEDs on the front panel of the SFB. LEDs are listed based on their location on the device, from left to right. Table 10 describes the ports/connections available on the front panel of the SFB.

Table 9: Switch Fabric Board LED Indicators

Label

Color

Status

Indicated Behavior

Alarm (pair)

Critical (Top)

Red

On steadily

A critical alarm is present in the system. A hardware component or software module has failed, or the network management interface is down.

Dark (unlit)

Off

No critical alarms are present in the system.

Non-Critical (Bottom)

Yellow

On steadily

A noncritical alarm is present in the system.

Examples of noncritical alarms include:

  • Memory usage is high on the Services Processing Unit (SPU); less than 10% available.
  • The maximum number of sessions has been reached.
  • The maximum number of tunnels has been reached.
  • HA status has changed.
  • Device temperature is too warm.

Dark (unlit)

Off

No alarms are present in the system.

SFB and HA (pair)

SFB STATUS

Green

On steadily

The SFB is operating normally.

Green

Blinking

The SFB is initializing.

Amber

On steadily

The switch fabric is operating normally, but the Ethernet interfaces are not operating normally.

Red

On steadily

The SFB has failed and is not operating normally.

HA

Green

On steadily

High availability is operating normally—All cluster members and all HA links are available.

Amber

On steadily

An alarm is present on the HA link. All cluster members are present, but some HA links are down. There are still enough links for full functionality, but performance could be impaired (reduced bandwidth could cause packets to get dropped, or reduced resiliency as a single point of failure might now exist).

Red

On steadily

A critical alarm is present on the HA. One or more cluster members are missing or unreachable; or active when secondary-path is engaged.

Dark (unlit)

Off

HA is disabled—Device is not configured for clustering or HA is disabled by secondary path.

CFM STATUS (pair)

SERVICE (top)

Green

On steadily

The SFB and all installed CFM cards are operating normally. The SERVICE LEDs on all installed CFM cards are green.

Amber

On steadily

The SFB or one or more of the installed CFM cards has reported a minor error condition. The SERVICE LEDs on the CFM cards reporting the error are amber.

Red

On steadily

The SFB or one or more of the installed CFM cards has failed. The SERVICE LEDs on the failed CFM cards are red.

Dark (unlit)

Off

One or more of the installed CFM cards are disabled. The SERVICE LEDs the disabled CFM cards are dark.

OK/FAIL (bottom)

Green

On steadily

The SFB and all installed CFM cards are operating normally. The OK/FAIL LEDs on all installed CFM cards are green.

Red

On steadily

The SFB or one or more of the installed CFM cards has failed. The OK/FAIL LEDs on the failed CFM cards are red.

Dark (unlit)

Off

One or more of the installed CFM cards are offline. The OK/FAIL LEDs the offline CFM cards are dark.

RE STATUS (pair)

RE1 (top)

Green

On steadily

The Routing Engine in slot RE1 is functioning as the master RE. Only one RE can be installed.

Blinking

The Routing Engine in slot RE1 is initializing.

Red

On steadily

Either the Routing Engine or Control Board function on RE1 has failed, and is not operating normally.

Dark (unlit)

Off

The RE1 slot is empty.

RE0 (bottom)

Green

On steadily

The Routing Engine on RE0 is functioning as the master RE. Only one RE can be installed.

Blinking

The Routing Engine in slot RE0 is initializing.

Red

On steadily

Either the Routing Engine or Control Board function on RE0 has failed and is not operating normally.

Dark (unlit)

Off

The RE0 slot is empty.

Power and Fan (pair)

POWER (top)

Green

On steadily

The device is receiving power. The Power Good signal for all installed power supplies has been received after RE initialization.

Blinking

The device is in one of two states:

  • Device is receiving power is in the process of booting up, prior to RE initialization.
  • Device is in the process of graceful shutdown.

Amber

On steadily

One of the power supplies has failed, but the power available from the remaining power supplies is sufficient to power all the installed components.

Red

On steadily

One or more of the power supplies have failed, and the power available from the remaining power supplies is not sufficient to power all the installed components.

Dark (unlit)

Off

The device is shut down.

FAN (bottom)

Green

On steadily

The cooling system is operating normally.

Red

On steadily

The cooling system has failed (one or more fans in the fan tray are not operating normally).

Note: All SFB status LEDs remain unlit until RE initialization is complete. The PWR LED blinks green until RE initialization is complete, at which point the LED becomes solid green.

Table 10: Switch Fabric Board Front Panel Ports and Connectors

Panel Label

Description

RE CONSOLE 0 (top),
RE CONSOLE 1 (bottom)

RJ-45 console ports used to connect to the Routing Engine inserted in slot RE0 or RE1, respectively.

AUX

Unused.

USB0 (top),
USB1 (bottom)

Universal serial bus connectors that can be managed and accessed by the master RE.

RE ETHERNET 0 (left),
RE ETHERNET 1 (right)

RJ-45 ports used to manage the RE. RE ETHERNET 0 connects to the Routing Engine in slot RE0. RE ETHERNET 1 connects to the Routing Engine in slot RE1 when present.

(On-board copper Ethernet ports)

Eight 10/100/1000 Ethernet over copper media ports. The ports use RJ-45 connectors and are numbered from 0-7, top to bottom, left to right.

(On-board fiber Ethernet ports)

Four Ethernet over fiber media ports. The ports use small form-factor connectors and are numbered 8-11 from left to right. Also supports Copper SFPs.

BITSCLK0 (top),
BITSCLK1 (bottom)

Unused.

CHASSIS CLUSTER CONTROL 0 (left),
CHASSIS CLUSTER CONTROL 1 (right)

SFP high availability ports. CHASSIS CLUSTER CONTROL 0 connects to the control functions on the RE present in RE0. CHASSIS CLUSTER CONTROL 1 connects to the control functions on the RE present in RE1.

Note: Juniper strongly recommends the use of Juniper transceivers. Juniper cannot guarantee correct operation if non-Juniper transceivers are used. The transceiver type can be different in each port, as long as a supported part number is used.
