The SFP Gigabit Ethernet ePIM, shown in Figure 11, uses small form-factor
pluggable transceivers (SFPs) that allow different interfaces to be used on
the ePIM. The ePIM supports 1000Base-LX, 1000Base–SX, and 1000Base-TX
SFPs only; it does not support 1000Base-LH SFPs.
The SFP Gigabit Ethernet ePIM cannot be manually configured. It
is set at 1000 Mbps and full duplex.
Connect the module with a single-mode or multimode optical cable.
NOTE: Configure Gigabit Ethernet interfaces up to a maximum MTU size of 9018
bytes.
For alarms, see the configuring and monitoring alarms information in
the J-series Services Router Administration Guide.
For instructions on installing and removing a PIM, see “Replacing a PIM” on page 144.
The LINK and TX/RX LEDs indicate link status and activity. Table 15
describes the meaning of the LEDs.
