Indicators —
LB510A: Power LED (solid yellow during normal operation);
WAN: Link LED (solid yellow when DSL link in established,

Ethernet: Link LED (solid yellow when valid signal is received on
the Ethernet port);
100 M LED (solid yellow when 100-Mbps link is negotiated);

normal operation);
DSL LED (solid green when a DSL link is established, blinks
once every second while the DSL link is training);
TM/ER LED (solid red to indicate a test mode in progress, blinks
red if an error is detected either during a test mode or
during normal DSL operation)
ME232A–ME233A only: Terminal LED (ME232A: Solid green when
control signals have been asserted [while operating as a
DCE] and when indication signals have been asserted [while
operating as a DTE]; On ME233A, solid green when serial
interface asserts DTR;
ME231A only: LINK LED (solid green when valid framing is
detected, blinks once per second when signal without valid
framing is detected;
LOSS LED: Blinks once per second to indicate either framing
errors or clock slips

Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives you
the wrong answer.
• You don’t have a purchase order number and the
tech refuses to help you.
• It’s 9 p. m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support they need is extremely
important when choosing a vendor. But even though
network managers pay anywhere from 10 to 20% of
their overall purchase price for a basic service and
support contract, the technical support and service they
receive falls far short of their expectations—and
certainly isn’t worth what they paid.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.
