MX10008 Routing and Control Board Components and Descriptions

MX10008 Routing and Control Board Description

The MX10008 Routing and Control Board (RCB) is responsible for system management in an MX10008 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.

MX10008 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

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 less than 5 seconds for diagnostic purposes, the RCB does not reset. The press event is logged in the RCB FPGA register.
- When pressed for greater than 5 seconds but less than 10 seconds, the RCB reboots and the reset-reason logs the button press event.
- When pressed for greater 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.
