
Network ports and the SFP port have LEDs to indicate link and activity status. If a
single mode and a multi-mode are both installed on the EMG unit, the device can be
configured to utilize one mode at a time.
- Power supply inlet: The unit accepts a 9 to 30 Vdc power input via a back-panel
connector. A universal AC power input (100-240V, 50/60 Hz) to 12 Vdc power supply brick
is available for use with the unit.
System Features
This section describes system features, interfaces, and ports of the EMG.
Access Control
The system administrator controls access to attached servers or devices by assigning access
rights to up to 128 user profiles. Each user has an assigned ID, password, and access rights.
Other user profile access options may include externally configured authentication methods such
as Radius, , NIS, and LDAP. Groups are supported in LDAP, RADIUS (using VSA), and
(using priv_lvl).
Device Port Buffer
The EMG unit supports real-time data logging for each device port. The port can save the data log
to a file, send an email notification of an issue, or take no action.
You can define the path for logged data on a port-by-port basis, configure file size and number of
files per port for each logging event, and configure the device log to send an email alert message
automatically to the appropriate parties indicating a particular error.
Console Port Interface
The EMG unit supports local access through a dedicated front panel serial console port (see
Figure 2-3 ). The console port supports the RS-232C (EIA-232) standard. RJ45 cabling (e.g.,
category 5 or 6 patch cabling) is used.
Figure 2-5 and Table 2-6 show the Console port and port pinout.
The console port supports the following baud rate options: 300, 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, 460800, and 921600 baud.
