Identifying the AXSM Models
The model number of an AXSM identifies the line s peed, line count, and number of bays (see Ta ble 3- 1.)
Note that the number of lines applies to an individual back card, so the total number of lines supported
by the front card equals the highest line number times the number of bays. The OC-48 card
AXSM-1-2488 has the lowest number of linesone. The highest number of lines exist on the
AXSM-16-155 and AXSM-16-T3E316, as the name indicates.
The MGX 8850 switch features the co n cep t of a bay. The bay refers to the upper or lower location of a
single-height card. (The switch has a double-height card cage, so a single-height back card necessarily
occupies either an upper or lower position.)
The T3/E3, OC-3, and OC-12 versions of the AXSM can have two back cards, one in bay 1 (upper
location of the back slot) and the se cond in b ay 2 (lo wer slo t). The MGX-AXSM-1 -2488 (OC-48 AXSM)
can have a back card in bay 1 only. For further descriptions and illustrations of the card sets, refer to
Cisco MGX 8850 Hardware Installation Guide, Release 2.
