Front Panel Indicators
All Indicators:
Green indicates normal operation.
Orange indicates an error condition.
Black indicates a disabled port.
DS3/E3 1/2:
Green if the unit has synchronized to a valid carrier signal pattern from the remote unit and data can
Flashes black each time a packet is received on this port.
Orange indicates no valid connection or loss of receive sync with remote unit.
Flashes orange/green if incoming signal is OK but either looped back or PPP session down..
Flashes orange/black if link is OK but waiting in a configured return-to-service delay period.
BER:
Green if OK.
Orange flash for each BPV bit error.
Orange steady for absence of DS3/E3 receive signal, loss of frame lock onto receive bit-stream,
Note: In a dual DS3/E3 unit, the BER will reflect the status of the operational link if one fails.
LAN1/2:
Green when a properly negotiated 100/1000BaseTX Full-Duplex or SFP LAN connection exists.
Flashes black each time a packet is received on this port.
Orange indicates no valid connection.
Flashes orange/black if in a configured "down if telecom down" mode.
Chapter 4: Remote Management HTTP and SNMP
Unit's IP/MAC Address
The source Ethernet MAC address of E3Switch converters is 00:50:C2:6F:xx:xx. The converter's current
IP and MAC addresses are always both shown at the HTTP management screen.
The unit's management interface can be initially contacted at either its automatic link-local IP address
e3switch.local as described below or at its initial numeric IP address described below. Note that after initial
setup, an operator may have changed the contact IP address to a new value and the initial addresses below
may not work. Prior to operator reconfiguration the unit will respond to HTTP, SNMP and ping requests to
its initial IP address.
For initial communication with the converter, it may be necessary to set the network address of the host port
communicating with the converter to 169.254.xxx.xxx with subnet mask 255.255.0.0. For security, routers
are advised not to forward packets with these link-local IP addresses, so a direct connection is advised.
Once initial contact has been established with the HTTP management interface of the converter, the
converter's IP address can be set to a new, static value if desired.
If a unit's operator-configured IP address is lost or forgotten, it can be recovered as described later in this
chapter.
be transferred on the link. Does not indicate PPP or PPPoE session status.
drive-level fault on transmit cable, or excessive receive bit errors.
Does not indicate PPPoE session status.
