C613-03043-00 REV B

Only tested and approved 5V Ethernet GBICs should be used with the AT-9800

Series switches.

Any combination of copper and fibre GBICs can be installed in the following

AT-9800 Series switches:

• AT-9812T

• AT-9812TF

• AT-9816GB

For the AT-9816GF, up to fourteen 1000BASE-T GBICs can be installed. The

actual number depends on the number of fibre GBICs also installed. Table 13

on page 29 lists the number of 1000BASE-T GBICs that can be installed in the

AT-9816GF for various copper/fibre combinations.

A range of GBICs have been tested and approved for use with the AT-9800 Series,

contact your authorised Allied Telesyn distributor or reseller for more information, or

visit www.alliedtelesyn.co.nz.

RX and TX terminal locations on SC fibre GBIC ports are the reverse of TX and RX

terminal locations on fixed SC fibre ports. When looking at an SC fibre GBIC from the

front, the RX terminal is on the left and the TX terminal is on the right.

GBIC 1000BASE-T Auto-Negotiation

1000BASE-T GBICs support only 1000 Mbps full duplex connections. Although

1000BASE-T GBICs will participate in auto-negotiation processes, they will

only advertise 1000 Mbps. Half duplex, 10BASE-T, and 100BASE-TX modes are

not supported.
