4.0 Configuration
On power up, the 922-MES starts a boot-up sequence that includes hardware and software initialization of the
Ethernet switching functions. This initialization period typically takes about 1.5 minutes and during this time all
Ethernet ports are disabled. After this period the switch configuration is loaded from an EEPROM with factory
default settings which are listed in section 4.1. These default settings can be changed via any Ethernet port
using a Modbus or Telnet connection and also saved to the EEPROM by the user to accommodate specific
switch functions and network topologies.
MES cards with diagnostics firmware ≥0xA3 support saving the user's switch configuration to EEPROM via
Telnet and Modbus. In addition to the standard boot-up process previously described, cards with uC DIAG FW
≥0xA3 have a second layer verification to ensure the MES core loads its configuration correctly. This layer of
verification consists of monitoring the MES core and ensuring the card boots-up correctly on power-up and that
the MES core operating system is running correctly. In the unlikely event that a failure is detected such that the
MES core cannot access the user EEPROM to load its configuration or the MES core stops responding, the card
will attempt to fix the problem on its own by self-rebooting (up to 3 times) and in where needed it will attempt to
re-load factory default backup switch configurations depending on the error detected. Note that error codes are
embedded in Modbus data and UDP heartbeat packets which are sent automatically by the card every 5 seconds
(factory default).
The MES card also includes a remote firmware upgrade feature which offers an upgrade path to support future
protocols or application specific requirements.
The card's default Ethernet port settings are as follows:
Copper ports CU1-CU8 are 10BASE-T /100BASE-TX / 1000BASE-T with auto-negotiation and auto
MDI/MDI-X enabled.
SFP ports SFP1-SFP2 are 1000BASE-X.
Supported packet sizes are standard Ethernet frames (64-1518 bytes), Ethernet II type frame (1536
bytes), huge frames (1916, 2048 bytes) and jumbo frames (9000 bytes).
The configuration options for the card that are saved in non-volatile memory EEPROM include the following:
Ethernet Switch Settings
o
Link speed, duplex and negotiation mode (per port)
o
MRP mode (MRM or MRC) for SFP ports SFP1-SFP2.
o
RSTP for copper ports CU1-CU8 (global)
Diagnostic Settings
o
Network, IP configuration
o
DHCP mode
o
UDP heartbeat frame rate and type
o
Serial diagnostics
Diagnostic interfaces to the card include Ethernet ports (any copper or SFP) for full diagnostics and control of
the board and a factory serial diagnostics interface via a 3.5 mm non-isolated RS-232 port which provides
basic read-only card configuration information and board status intended for factory bench testing.
The MES card is fully programmed at the factory (core, diagnostics, EEPROMs, etc.). MES core firmware options
are shown in the table below. By default the card is shipped with core firmware P/N: 922-1008-50 unless
otherwise requested or specified by the customer. The MES card's diagnostics firmware (uC DIAG) P/N 922-
1008-00 is the same for both MES core FW options.
