Cooling Modules; Switch Fabric Module - Avaya Virtual Services Platform 9000 Series Installation Manual

• 150 W each for the two IO fan trays
• 65 W each for the two SF fan trays
Refer to Component input power
Power feed redundancy
Avaya recommends that you use two separate power feeds to plug the AC power supplies.
The power supplies in the 9012 chassis are divided in two shelves. The top shelf (shelf "A")
consists of power supplies 1, 2, and 3, while the bottom shelf (shelf "B") consists of power
supplies 4, 5, and 6. If you use n + n redundancy and plug the power supplies from the top
shelf in power feed "A", and the power supplies from the bottom shelf in power feed "B", this
gives you power feed redundancy. Each shelf can provide 3600 W or 6000 W, depending if
you use 100-120 V AC or 200-240 V AC. Ensure that each power supply connects to a
dedicated breaker.

Cooling modules

The Avaya Virtual Services Platform 9000 chassis uses four cooling modules. Two cooling
modules at the front of the chassis cool the CP and interface modules. Two cooling modules
at the back of the chassis cool the SF modules.
You install the cooling modules for the interface and CP modules at the front of the chassis.
The cooling modules plug into the midplane. The cooling air flows from left to right, as viewed
from the front. A green LED indicates correct fan operation.
You install the cooling modules for the SF modules at the back of the chassis. The cooling air
flows from front to back to cool the SF and auxiliary modules.
See Avaya Virtual Services Platform 9000 Installation — Cooling Modules, NN46250-302 for
information about installing cooling modules.

Switch Fabric module

With Release 3.1, you must install a minimum of three SF modules in the chassis. Avaya
recommends that you install a minimum of four SF modules for redundancy. You must install
an SF module in slots SF1 and SF4; install a third SF module in one of the remaining slots.
Each SF module connects to the ten different interface module slots and the two CP module
slots simultaneously. You can install a maximum of six SF modules in each chassis in a 5 + 1
redundancy configuration.
The SF module slot numbers increment from right to left when you view the chassis from the
rear. The slot location determines the module function. Slots 1 and 4 provide the arbitration
and scheduling for traffic (and therefore, bandwidth management) from the interface modules
