MxK Hardware Installation Guide
The MXK 319 chassis is a 19 inch wide and 3U high unit with 7 line card
slots and 2 uplink card slots. The MXK 3U chassis also has a removable fan
controller with six fans and alarm LEDs.
In the 3U chassis the two bottom right slots, slots a and b, are only for the
uplink cards. There are 5 slots in the left hand column, designated 1 to 5, and
two slots in the upper right hand column, designated 6 and 7 for line cards.
Any type of line card can be installed in those slots. Cables and connectors are
accessed from the front of the chassis.
Cables and connectors (except for power cables) are accessed from the front
of the chassis. For the MXK 319, power cables enter the device in the rear of
the unit. The airflow through the unit is from the right side to the left side
(when facing the front of the chassis). See
and ground the chassis on page 50
Uplink card guidelines
Observe the following guidelines when installing slot cards into the MXK 819
and MXK 823 chassis:
•
The two uplink cards are the only cards that can be installed in the two
middle slots, slots a and b.
•
Line cards can be installed in any of the remaining slots and can exist in
the same chassis.
