Power Supply Selection - Avaya 8800 Installation Manual

Technical specifications
Caution:
For instances where you install a significant number of long-range SFPs, SFP+s and XFPs,
you must ensure that you have sufficient power available to power these optical devices.
• 1000BASE-LX, 1000BASE-BX, 1000BASE-XD CWDM, 1000BASE-ZD CWDM,
1000BASE-EX SFPs
Short-range (SR) SFPs consume 0.85 W for each transceiver.
For 1000BASE-LX, 1000BASE-BX, 1000BASE-XD CWDM, 1000BASE-ZD CWDM: add
0.15 W for each SFP
For 1000BASE-EX: add 0.40 W for each SFP
• 10GBASE-LR, 10GBASE-LRM and 10GBASE-ER enhanced SFPs (SFP+)
All SFP+ transceivers have a power consumption of 2.5 W (1 W for each port and an
additional 1.5 W for each installed transceiver). There is no difference in power
consumption between short and medium/long/extended range SFP+s.
• 10GBASE-LR, 10GBASE-LRM, and 10GBASE-ER XFPs
Short range XFPs consume 2.5 W for each transceiver.
For 10GBASE-LR/LRM; add 1 W for each installed XFP
For 10GBASE-ER; add 2 W for each installed XFP
For example, if you use two 10GBASE-ER XFPs in a 8612XLRS module that otherwise has
two 10BASE-SR XFPs, add 2*2 W to 257.9 W for a total of 261.9 W.
You can also calculate chassis and module power consumption using the Power Management
Calculator Avaya ERS 8800/8600 Power Management Calculator, (NN48500-519), available
on the Avaya Technical Support Web site. You can find the calculator at
support with the rest of the ERS 8800/8600 documentation.

Power supply selection

The following table lists the power available from each power supply supported with the Avaya
Ethernet Routing Switch 8800/8600.
Power management identifies the available power in the chassis, called the power budget, and
determines if enough power is available to operate the installed components. For a complete
description of the power management feature and configuration instructions, see Avaya
Ethernet Routing Switch 8800/8600 Administration, NN46205-605.
