Activity indicators
—Adjacent to the on-board RJ-45 connector, two green LEDs
indicate network activity and link speed. One LED indicates network activity and lights
when data is present; therefore, it blinks during data transmission. The other LED
indicates link speed and lights at 100Mbps and turns off at 10Mbps.
Jumpers
—No jumpers are installed in the standard configuration.
Replacing AR-P15 components

OTE
:
Before performing these procedures, you must power off and unplug the copier,
and remove the AR-P15 from the copier. See the AR-P15 installation instructions (not
provided in this guide).
The AR-P15 has two DIMM sockets: one 128MB DIMM in J49 and, optionally,
another 128MB DIMM in J48 (see Figure A on page 2 and also “Replacing or adding a
DIMM” on page 7).
When the AR-P15 is installed inside the copier, the connectors for external devices are
easily accessible at the faceplate (see Figure G on page 15).
Wear an ESD grounding wrist strap and follow standard ESD (electrostatic discharge)
precautions while performing these procedures.
