QFX10000 Routing and Control Board Description

The Routing and Control Board (RCB) is responsible for system management in a QFX10008 or QFX10016 (see Figure 1). The switch chassis can run with one or two RCBs. The base configurations ship with one RCB that can be expanded with a second RCB for a fully-redundant system. When two RCBs are installed, one functions as the primary and the second as a backup. If the primary RCB is removed, the backup restarts and becomes the primary.

RCB Functions
RCB Components

RCB Functions

The RCB integrates the control plane and Routing Engine functions into a single management unit. Each RCB provides all the functions needed to manage the operation of the modular chassis:

System control functions such as environmental monitoring
Routing Layer 2 and Layer 3 protocols
Communication to all components such as line cards, Switch Interface Boards (SIBs), and power and cooling
Transparent clocking
Alarm and logging functions

RCB Components

Each RCB consists of the following internal components:

Quad-core 2.5 GHz CPU
32 GB SDRAM
50 GB or 100 GB onboard SATA SSD

Other standard interfaces are shown in Figure 2.

Figure 2: RCB Faceplate

1 — RCB status LEDs	5 — USB 2.0 port
2 — Console port	6 — SATA SSD slot
3 — PTP-capable connections: SMB In, SMB Out, 10 MHz In, 10 MHz Out	7 — Reset button
4 — Ethernet management ports: RJ-45 for 10/100/1000 BASE-T (em0) and small-form factor pluggable (SFP) for fiber (em1). If both copper and fiber cables are installed, the RJ-45 is the default.	8 — Four SFP+ ports (reserved for future use)

Note:

You can use either management interface, em0 or em1 when the RCB is running as the primary RE. Use only em1 when the RCB is running as the backup RE.

QFX10000 Routing and Control Board LEDs

The QFX10000 Routing and Control Boards (RCBs) have four types of LED indicators (see Figure 3).

RCB Status Panel LEDs

The RCB status panel LEDs indicate the state of the RCB (see Figure 4).

Figure 4: RCB Status Panel LEDs

1 — Power (PWR) LED	3 — Primary (MST) LED
2 — Status (STS) LED	4 — Offline button

Table 1 describes the LEDs on the RCB status panel.

Table 1: Routing Control Board Status LEDs
LED	Color	State	Description
PWR	Green	On steadily	The RCB is receiving adequate power.
	Yellow	Blinking	The RCB has detected an error.
	Dark	Unlit	The RCB is not powered up.
STS	Green	On steadily	The RCB is online and functioning correctly.
	Green	Blinking	The beacon feature is enabled.
	Yellow	On steadily	The RCB is booting.
	Yellow	Blinking	The RCB has detected an error.
	Dark	Unlit	The power supply is switched off.
MST	Green	On steadily	The RCB is the primary.
MST	Dark	Unlit	The RCB is the backup.

QFX10000 Management Port LEDs

There are two management ports on the RCB of a QFX10008 and QFX10016 that have LEDs that indicate link status and link activity. These two ports, located on the RCB panel between the clocking connections and the USB port, are both labeled MGMT. The left management port is an SFP cage that can accommodate up to 1G copper or fiber connections (see Figure 5). The copper (RJ-45) port has separate LEDs for status and activity. The fiber (SFP) port has a combination link and activity LED.

Figure 5: Management Port LEDs on a QFX10000

1 — Status LED (RJ-45)	3 — Link LED–Green indicates the link is up; blinking indicates activity (SFP)
2 — Activity LED (RJ-45)

Table 2 describes the RJ-45 management port LEDs, and Table 3 describes the SFP status LEDs.

Table 2: RJ-45 Management Port LEDs on a QFX10000 RCB
LED	Color	State	Description
Port speed	Unlit	Off	The port speed is 10 MB.
	Green	Blinking	The port speed is 100 MB.
	Green	On steadily	The port speed is 1000 MB.
Link/Activity/Status	Unlit	Off	No link is established, there is a fault, or the link is down.
	Green	On steadily	A link is established.
	Green	Blinking	There is link activity.
	Yellow	Blinking or flickering	The beacon feature is enabled.

Table 3: SFP Management Port LEDs on a QFX10000 RCB
LED	Color	State	Description
Link/Activity/Status	Unlit	Off	No transceiver is present.
	Green	On steadily	A link is established. The interface is up.
	Green	Blinking or flickering	The beacon feature is enabled.
	Yellow	Blinking	An error has occurred.

SATA SSD LEDs

The Serial Advanced Technology Attachment (SATA) solid-state drive (SSD) LEDs indicate the status of the optional drive.

Table 4 describes the LEDs for the optional SATA drive.

Table 4: Control Board Status LEDs
LED	Color	State	Description
SSD	Green	On steadily	A SATA drive is present.
	Green	Blinking	The drive is active.
	Yellow	On steadily	The drive is active.
	Dark	Unlit	A drive is not installed.

Virtual Port Connections

The four small form-factor pluggable plus (SFP+) ports are reserved for future use.
