8. The apparatus of claim 1 wherein the coolant distribution module comprises a plurality of quick disconnects for mating with coolant distribution lines on a plurality of the modules in said second group of modules.
9. The apparatus of claim 1 wherein the coolant passes through a heat exchanger external to the chassis.
10. The apparatus of claim 1 wherein the coolant distribution module comprises internal connectors for mating with connectors on said second group of the modules receiving the coolant, the internal connectors offset from a location of an orthogonal connector on an air cooled module.
11. The apparatus of claim 1 wherein the coolant distribution module comprises internal connectors for mating with connectors on said second group of the modules receiving the coolant, the internal connectors operable to move between a recessed position when mating with an air cooled module and an engaged position when mating with the connectors on said second group of the modules.
12. An apparatus comprising:
a coolant distribution module for insertion into a chassis of a network device in a first orientation for delivering coolant to one or more modules inserted into the chassis in a second orientation orthogonal to said first orientation, the coolant distribution module comprising:
a plurality of internal connectors for connection to said one or more modules; and
distribution lines for delivering coolant to said plurality of internal connectors.
13. The apparatus of claim 12 wherein the coolant distribution module further comprises at least one external connector for receiving the coolant from an external source.
14. The apparatus of claim 12 wherein at least one of the internal connectors is configured for distributing the coolant to a second coolant distribution module inserted into the chassis in said second orientation for distributing the coolant to one or more modules inserted into the chassis in said first orientation.
15. The apparatus of claim 12 wherein said one or more modules comprises line cards.
16. The apparatus of claim 12 wherein said one or more modules comprises a plurality of modules, at least one of the modules configured only for air cooling by a fan in the chassis.
17. A method comprising:
receiving coolant at a coolant distribution module inserted into a slot of a chassis in a first orientation;
delivering coolant to a plurality of modules inserted into a plurality of slots in the chassis in a second orientation orthogonal to said first orientation for cooling components on the modules; and
delivering coolant to a second coolant distribution module inserted into one of the slots in said second orientation for delivering the coolant to a plurality of modules inserted into slots of the chassis in said first orientation.
18. The method of claim 17 further comprising air cooling one or more modules inserted into the chassis.
19. A method comprising:
receiving coolant at a coolant distribution module inserted into a slot of a chassis in a first orientation;
