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 is receiving a valid WAN signal with no alarm conditions.
Flashes black each time a packet is received on this port
Orange steady indicates loss of the incoming WAN AMI signal.
Flashes orange/green if incoming signal exists, but an alarm condition is being received.
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,
drive-level fault on transmit cable, or excessive receive bit errors.
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.
Chapter 4: Remote Management HTTP and SNMP
Monitors contain both an HTTP management interface, which may be accessed via a web browser, and an
SNMPv2c agent through either LAN port (if second SFP LAN port has been purchased/enabled)
Unit's IP/MAC Address
The source Ethernet MAC address of E3Switch Monitors is 00:50:C2:6F:xx:xx. The Monitor's current IP
and MAC addresses are always both shown at the HTTP management screen.
The Monitor'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 Monitor, it may be necessary to set the network address of the host port
communicating with the Monitor to 169.254.xxx.xxx with subnet mask 255.255.0.0. Security protocols
advise routers 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 Monitor, the
Monitor'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.
