3.4.3. Management Processor
The GES provides an ARM 9 processor running at 96MHz for both internal and customer
specified functions. This processor is in-band allowing control by any device on the
Ethernet network that is connected to the GES.
This processor is lightly loaded after initialization of the GES allowing customer specified
functions to use most of the available processing power if required.

GES – Users Manual
Page 5 of 33
The primary purpose of this processor is to:
•Initialize the Ethernet Switch IC for GES default operation
•PBIT and CBIT
•Customer specific functions if required
3.4.4. Input Power
The connections shown in Table 3-1 with a Red background are Power Connections.
The input power requirements are as specified in MIL-STD-704A:
Aircraft, 28 VDC, Category B (curves 2 &3 of Fig. 9)
During normal operations the average power consumption with all 12 ports connected at
1 GB speed is 17 watts. Input current is internally limited to 2 amps.

Both ports are RS-232 compatible and operate only at:
•115.2K baud
•1 Stop Bit
•No Parity
•No Flow Control
The DEV1 port supports out-of-band configuration management of the GES.
The DEV2 serial port is available for customer specific uses. Contact Aeronix if you
would like custom programming for this port such as an Ethernet to Serial bridge or
sensor/actuator to Ethernet.See section 6.2 for current details.

5. Bootloader
The GES management processor (STR912) executes code directly from flash. The GES
supports running from either of two internal banks of flash. The smaller bank is
dedicated to the bootloader. This allows upgrading of the GES application software in
the field over the network. Immediately after power up the bootloader allows nine
seconds to begin a code load before it jumps to the application that executes out of the
main (larger) bank of flash.

GES – Users Manual
Page 8 of 33
6. Menu Interface
The GES Menu Interface is used for out-of-band control of the GES. It provides the
ability to customize configurations and status monitoring.
6.1. Required Hardware
To interact with the STR9 CPU, the following hardware is required:
•Power supply
•Gigabit Ethernet Switch, Part Number AE101264
•Computer with Terminal Emulation software (i.e.: TeraTerm under Windows)
6.2. Serial Port Setup
Serial port setup is 115,200 Baud with N81 and no hardware or software handshaking.
The command system is tied to DEV1.
The second UART (DEV2) will reply to an input character with a message string “Saw a
NN on port 1\n”, where NN is a hexadecimal representation of the input character.
6.3. Menus
6.3.1. How the menus work
All menu selections require a single character to be input. There is no need to enter a
carriage return.
6.3.2. Menu Header

6.3.4.2. ‘c’ – show configuration
Display the contents of the configuration structure (Displayed below is the default
configuration). This configuration is stored in flash memory and may be modified using
the serial port and saved. This configuration survives power cycling of the GES unit.
IP_address[0]: 6401A8C0 (192.168.1.100)
IP_address[1]: 64811FAC (172.31.129.100)
IP_mask[0]: 00FFFFFF (255.255.255.0)
IP_mask[1]: 00FFFFFF (255.255.255.0)
mirror_destination: 2
switch_mirror[0..11]: N B N N N N N N N N N N
cpu_switch_mirror: N
crc32: 3875E0CC
The management CPU supports two IP addresses. This allows the GES management
CPU to potentially participate in two distinct subnets. The primary IP and net mask are
shown as IP_address[0] and IP_mask[0]. The secondary IP and net mask are shown
as IP_address[1] and IP_mask[1].
The GES supports port mirroring. This allows monitoring of traffic going in or out of any
of the ports. The mirror_destination is the external port number where the mirrored
traffic is directed. The switch_mirror[0..11] describes the mirroring state of each
external port of the GES. An ‘N’ indicates no mirroring, an ‘I’ indicates ingress mirroring,
an ‘E’ indicates egress mirroring, while a ‘B’ indicates both ingress and egress mirroring.
The cpu_switch_mirror is much like the switch_mirror[0..11], but it indicates the
mirroring for data going to and from the CPU port.
NOTE: Port mirroring is enabled using a GES Status Command UDP packet with the
GES Traffic Capture Mode bit set. Once enabled, the mirroring can only be reset with a
power cycle of the GES.

GES – Users Manual
Page 11 of 33
The crc32 is generated internally and is used to verify the stored values in flash. If the
crc32 fails the GES reverts to the default values.
6.3.4.3. ‘p’ – set primary IP address and netmask
The GES will prompt for the new IP address (saved as IP_address[0]). It expects it in
dotted notation followed by a carriage return. Any characters other than 0-9, a period or
a carriage return cause the update to be aborted. After the IP address is entered, the
GES prompts for the netmask (saved as IP_mask[0]). The netmask must also be
entered in dotted notation. At the conclusion of a successful IP address and netmask
input the GES writes the configuration to flash.
6.3.4.4. ‘s’ – set secondary IP address and netmask
The GES will prompt for the new IP address (saved as IP_address[1]). It expects it in
dotted notation followed by a carriage return. Any characters other than 0-9, a period or
a carriage return cause the update to be aborted. After the IP address is entered, the
GES prompts for the netmask (saved as IP_mask[1]). The netmask must also be
entered in dotted notation. At the conclusion of a successful IP address and netmask
input the GES writes the configuration to flash.
6.3.4.5. ‘d’ – set mirror destination
The GES prompts for an entry (0-9,a,b), where external ports 10 and 11 are represented
by ‘a’ and ‘b’ respectively. At the conclusion of a successful mirror destination input the
GES writes the configuration to flash.
6.3.4.6. ‘m’ – set mirror details
The GES prompts for each port in sequence, expecting ‘I’ (for ingress),’E’ (for egress),’N’
(neither ingress nor egress),’B’ (both ingress and egress). This updates the
switch_mirror[0..11] field. At the conclusion of a successful mirror details input the
GES writes the configuration to flash.
6.3.4.7. ‘u’ – set cpu mirror details
The GES prompts for the management CPU mirroring configuration, expecting ‘I’ (for
ingress),’E’ (for egress),’N’ (neither ingress nor egress),’B’ (both ingress and egress). At
the conclusion of a successful CPU mirror details input the GES writes the configuration
to flash.
6.3.4.8. ‘f’ – write out current config to flash
Commands the GES to write out the current configuration to flash. This is useful if you
want to burn the default configuration to flash. Normally any update of any of the
configuration fields causes the configuration to be saved to flash.
6.3.4.9. ‘b’ – back to main menu
Return to the main menu.

7. Management Processor Ethernet Communications
7.1. Network Communications Supported
The GES management processor supports ARP, ICMP (ping), and UDP communications. UDP
traffic is supported on port 3500. All fields are sent in network byte order. This means that fields
larger than a byte will be read and written using standard access routines. These routines are
host-to-network-short “htons()”, host-to-network-long “htonl()”, network-to-host-short “ntohs()”
and network-to-host-long “ntohl()”.

Word 2, Bit 0 – GES Summary Status 1Hz Update Request (0 – OFF, 1 – Request 1Hz updates)
Word 2, Bit 1 – GES Initiated BIT Status Request (0 – OFF, 1 – Request IBIT status)
Word 2, Bit 2 – GES Traffic Capture Mode (0 – nothing, 1 – Begin Traffic Capture Mode)
Word 2, Bit 3 – GES Operational Status Mode (0 – OFF, 1 – Operational Status Mode Active)
Word 2, Bit 4 – GES Operational Performance Mode (0 – OFF, 1 – Operational Performance
Mode Active)
When the GES receives a GES Status Command it will respond with a GES Summary Status
packet.
The GES also supports up to two requests for 1Hz GES Summary Status updates. The first two
requestors will receive GES Summary Status messages at approximately 1Hz intervals. If a
request for 1Hz updates comes from the same IP address, but from a different port it will replace
the previous 1Hz update request.
