Limitations. The Gigabit Ethernet ePIM has the following limitations:
■ Gigabit Ethernet ePIMs do not support SNMP.
■ Configure Gigabit Ethernet ePIM interfaces up to a maximum MTU size of
9018 bytes.
Installation. You can install Gigabit Ethernet ePIMs in any high-speed slot as follows:
■ J4350—Install up to two Gigabit Ethernet ePIMs in slots 3 and 6.
■ J6350—Install up to four Gigabit Ethernet ePIMs in slots 2, 3, 5, and 6.
NOTE: High-speed slots are labeled with an E on the front-panel slot number diagram.
To install or remove a PIM, see “Replacing a PIM” on page 174.
Interface LEDs. The LINK and TX/RX LEDs indicate link status and activity.
Table 23 on page 54 describes the meaning of the LEDs.
