SCBE-MX Description

 

The MX Enhanced Switch Control Board (SCBE-MX) for MX960, MX480, and MX240 routers serves the carrier Ethernet services router and carrier Ethernet transport markets that require higher-capacity traffic support, demanding greater interface density (slot and capacity scale), as well as improved services. The SCBE-MX provides:

  • 160 Gbps/slot bandwidth with redundant fabric support, and improved fabric performance by using the next-generation fabric (XF) chip

  • A central clocking module and a centralized clocking architecture that supports clock cleanup and distribution. The Stratum 3 clock module performs clock monitoring, filtering, and holdover in a centralized chassis location

  • Full performance with fabric redundancy for higher capacity line cards such as 16x10GE and MPC3

The Routing Engine installs directly into a slot on the SCBE-MX (see Figure 1).

Table 1 lists the maximum number of SCBE-MXs you can install in the MX chassis, the corresponding slot labels, and the backup slot used for redundancy. If any slots are empty, you must install a blank panel.

SCBE-MX LEDs

The FABRIC ACTIVE, FABRIC ONLY, and OK/FAIL LEDs indicate the status of the SCBE-MX. The BITS, GPS, and UTI LEDs (next to the EXT CLK port) indicate the status of the respective clocking interface. Table 3 describes the behavior of the SCBE-MX LEDs.
