MX2008 Host Subsystem

MX2008 Host Subsystem Description

The host subsystem provides routing protocol processes, as well as software processes that control the router’s interface, the chassis components, system management, and user access to the router. These routing processes run on top of a kernel that interacts with the Packet Forwarding Engine. The MX2008 host subsystem consists of two Routing and Control Boards, or RCBs. The RCB is an integrated board and a single FRU that provides Routing Engine and Control Board 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 MX2008 RCB is similar to the native CB-REs supported by MX2000 routers, with the only difference being that the MX2008 RCB is less than half the size of the MX2000 CB-RE.

Note:

Install two RCBs for redundant protection. If you install only one RCB, you can install it in slot 0 or slot 1.

CAUTION:

If one of the RCBs fails, do not remove the failed RCB until you have a replacement or blank panel to install.

MX2008 Routing and Control Board (MX2008 RCB) Description

The MX2008 Routing and Control Board (MX2008 RCB) is an integrated board and a single FRU that provides Routing Engine and Control Board functionality.

The REMX2008-X8-128G RCB is equipped with a 8-Core 2.3 GHz processor, 128 GB memory, and two 200 GB SSDs and also supports Secure Boot for enhanced boot security.

The REMX2008-X8-64G-LT RCB is equipped with a 8-Core 2.3 GHz processor, 64 GB memory, and two 100 GB SSDs. The RCB is equipped with limited encryption support only.

Supported RCBs

The following are some key attributes of the MX2008 RCB:

The RCB combined the Control Board and the Routing Engine in a single FRU.
The RCB is hot-pluggable.
The RCB is less than half the size of native MX2000 CB-RE.

The MX2008 router supports the following RCBs:

REMX2008-X8-64G
REMX2008-X8-64G-LT
REMX2008-X8-128G

RCB Function

The RCB runs Junos OS. Software processes that run on the RCB maintain the routing tables, manage the routing protocols used on the router, control the router interfaces, control some chassis components, and provide the interface for system management and user access to the router.

RCB Slots

The user can install one or two RCBs in the router. Each RCB is a combined Routing Engine and Control Board in one unit. A USB port on the RCB accepts a USB storage device that enables you to load Junos OS. You can install the RCBs into the front of the chassis in vertical slots labeled 0 and 1. If two RCBs are installed, one functions as the primary and the other acts as the backup. If the primary RCB fails or is removed and the backup is configured appropriately, the backup takes over as the primary. If no RCB is installed in a slot, install a blank panel in the slot.

A minimum of one RCB must be installed in either slot 0 or slot 1 at all times.

CAUTION:

If one of the RCBs fails, do not remove the failed RCB until you have a replacement or blank panel to install.

Table 1: Components on the RCB
Function No.	Label	Description
1	ONLINE, MASTER, and OK/FAIL	There is one bicolor LED for each RCB control. The ONLINE LED indicates that the RCB is transitioning online and functioning properly. The MASTER LED indicates that this board is a primary RCB, and the OK/FAIL LED indicates the RCB has failed.
2	SSD0 and SSD1	LEDs shows the state of the two solid-state drives (SSDs) in the RCB.
3 4	GPS, UT1, and BITS	These ports shows the external clocking interface status. There is one bicolor LED for each external clock interface—GPS, UTI and BITS.
5	RESET	This button used to reboot the RCB.
6	AUX	This port is used to connect a laptop, modem, or other auxiliary unit.
7 12	CLK0 and CLK1	Connects the RCB to two external clock interfaces for BITS and GPS function through a serial cable with an RJ-45 connector.
8 11	LNK-0 and LNK-1	Two SFP+ ports connects the RCB through an Ethernet connection to support hardware diagnostics and JCS port testing. The port supports two 1–Gbps or 10-Gbps connections. The LED on these ports are associated with each of the SFP+ port (XGE-0 and XGE-1) and indicates the connection in use.
9	USB	This port is used to install a USB flash drive that contains Junos OS.
10	MGT	This port is a dedicated management channel for device maintenance. It is also used for system administrators to monitor and manage the MX2008 router remotely.
13	CONSOLE	This port is used to configure the MX2008 router.

RCB Interface Ports

Three ports, located on the RCB, connect the RCB to one or more external devices on which system administrators can issue Junos OS CLI commands to manage the router. In addition, four ports located on the RCB include, two 10-Gigabit Ethernet SFP+ interface connectors supporting hardware diagnostics (JCS port testing), and two external clock interfaces for BITS and GPS function.

The RCB interface ports with the indicated labels function as follows:

AUX—Connects the RCB to a laptop, modem, or other auxiliary device through a serial cable with an RJ-45 connector.
CONSOLE—Connects the RCB to a system console through a serial cable with an RJ-45 connector.
MGT—Connects the RCB through an Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for out-of-band management. The port uses an autosensing RJ-45 connector to support 10-Mbps, 100-Mbps, or 1000-Mbps connections. Two small LEDs on the bottom of the port indicate the connection in use: the LED flashes yellow or green for a 10-Mbps, 100-Mbps, or 1000-Mbps connection, and the LED is lit green when traffic is passing through the port.

The Control Board interface ports function as follows:
USB—Provides a removable media interface through which you can install the Junos OS manually. Junos OS supports USB version 1.0 and later.
LNK-0 and LNK-1—Two SFP+ port connect the RCB through Ethernet to support two 1-Gbps or 10-Gbps connections to any external control box. Two small LEDs on the side of each SFP+ port indicate the connection in use: the LED flashes yellow when there is no link, flashes green when there is activity, or is lit green for a 1-Gbps or 10-Gbps connection.
CLK-0 and CLK-1—Connect the RCB to an external clock device through a serial cable with an RJ-45 connector.

MX2008 RCB LEDs

The Routing and Control Board (RCB) is an integrated board and a single FRU that provides Routing Engine and Control Board functionality.

Each Routing Engine part on the RCB has three LEDs that indicate its status. The LEDs, labeled ONLINE, MASTER, OK/FAIL, are located directly on the faceplate of the RCB. Table 2 describes the functions of the Routing Engine interface of the RCB. There are three LEDs on the craft interface for each Routing Engine (RE0 and RE1). These LEDs are labeled MASTER, ONLINE, and OFFLINE.

Note:

The GPS LED is lit when the RCB is connected to an external clocking interface.

The Control Board, part of the host subsystem, has a set of bicolor LEDs that display its status. The LEDs, labeled LINK, GPS, and BITS, are located directly on the faceplate of the RCB. Table 2 describes the functions of the Control Board interface of the RCB. There are two LEDs on the craft interface for each Control Board—one labeled CB-RE0 (far left) and one labeled CB-RE1 (far right). For more information about the RCB and Routing Engine LEDs on the craft interface, see MX2008 Component LEDs on the Craft Interface.

Note:

The memory in Table 3 indicates the amount of total memory. To determine the amount of available memory, issue the show chassis routing-engine CLI command.

On routers that accept two Routing Engines, you cannot mix Routing Engine types except for a brief period (one minute or so) during an upgrade or downgrade to two Routing Engines of the same type.
