MX10004 Routing and Control Board Components and Descriptions

MX10004 Routing and Control Board Description

The Routing and Control Board (RCB) is an integrated board and a single field-replaceable unit (FRU) that provides Routing Engine and Control Board (CB) functionality. The Routing Engine performs all route-processing functions, whereas the CB performs chassis control and management plane functionality. The RCB provides control plane functions. You can install one or two RCBs on the router. Each RCB functions as a unit.

The MX10004 Routing and Control Board (RCB) is responsible for system management in an MX10004 router (see Figure 1). The chassis can run with one or two RCBs. The base configuration ships with one RCB, while a redundant configuration ships with two RCBs. When two RCBs are installed, one functions as the primary and the second as a backup. If the primary RCB is removed, the backup becomes the primary if graceful Routing Engine switchover (GRES) is configured.

MX10004 supports the following Routing Engines:

JNP10K-RE1
JNP10K-RE1-LT
JNP10K-RE1-128G

Routing and Control Board Functions

The Routing and Control Board (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 Fabric Boards (SFBs), and power and cooling
Transparent clocking
Alarm and logging functions

6 — XGE-0 and XGE-1 not used (reserved ports)	13 — Console (CONSOLE) port
7 — ToD—Time-of-day (TOD) port	14 — RCB status LEDs

Each RCB consists of the following internal components:

CPU—Runs Junos OS to maintain the routing tables and routing protocols.
EEPROM—Stores the serial number of the Routing Engine.
DRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes.
One 10-Gigabit Ethernet interface between the Routing Engine and Switch Fabric Board.
One USB port—Provides a removable media interface through which you can install Junos OS manually. The Junos OS supports USB versions 3.0, 2.0, and 1.1.
Management ports—Two ports, one copper (RJ-45 port) and one SFP port, provide access to management devices. Use only one of the two management ports at a time.

Use an RJ-45 connector for the copper port.

Use a fiber optic connector for the SFP port.

Do not use copper SFP or SFP-T modules in the SFP port because they are not supported.
RESET button—When pressed, reboots the RCB as detailed below:
- When pressed for fewer than 5 seconds for diagnostic purposes, the RCB does not reset. The press event is logged in the RCB FPGA register.
- When pressed for more than 5 seconds but fewer than 10 seconds, the RCB reboots and the reset-reason logs the button press event.
- When pressed for more than 10 seconds, the RCB reboots with an option for BIOS recovery.
LEDs—Provide status of the Routing Engine.
Online/Offline Button—When the RCB is online, and if the button is pressed for more than 4 seconds, the RCB goes offline. When the RCB is offline, and if the button is pressed more than 4 seconds, the RCB starts booting.

Note:

For specific information about Routing Engine components (for example, the amount of DRAM), issue the show vmhost hardware command.

MX10004 Routing and Control Board LEDs

The MX10004 Routing and Control Boards (RCBs) have various types of LED indicators. Figure 3 shows the LEDs on the Routing and Control Boards (JNP10K-RE1).

Routing and Control Board Status Panel LEDs

Table 1 describes the LEDs on the RCB status panel.

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

SATA SSD LEDs

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

Table 2 describes the LEDs for the secondary SATA drives.

DISK1 and DISK2	Green	On steadily	A SATA drive is present.
	Green	Blinking	The drive is active.
	Yellow	On steadily	The drive is active.
	Dark	Unlit	The drive is not installed.

Clock LEDs

The clock LEDs indicate whether clocking is active.

Table 3 describes the clock LEDs.

MX10004 Management Port LEDs

The two management ports on the RCB of an MX10004 router 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 (RJ-45) is for 10/100/1000 BASE-T connections, and the right port (SFP) is for 10/100/1000 BASE-T and small form-factor pluggable (SFP) 1000 BASE-X connections (see Figure 4). The copper (RJ-45) port has separate LEDs for status and activity. The fiber (SFP) port has a combination link and activity LED.
