For example, an ONS 15454 equipped with NEBS3/NEBS3E chassis and this configuration, which
creates maximum draw:

Two Timing Communication and Control+ (TCC+) cards.

●

Two Cross Connect-Virtual Tributary (XC-VT) cards.

●

Ten E100T-12 cards.

●

Two Optical Carrier (OC)48 Intermediate Reach (IR) 1310.

●

One Alarm Interface Controller (AIC).

●

According to the normal consumption from Table 1, this configuration would have this power
consumption: (2 x 9.82W) + (2 x 34.40W) + (10 x 65.00W) + (2 x 32.20W) + 6.01W = 806.85W +
55W (fan tray) = 863.85W.

For example, an ONS 15454 equipped with ANSI chassis and this configuration, which creates
maximum draw:

Two TCC2 cards.

●

Two XC10G cards.

●

Ten E100T-G cards.

●

Two OC192 Long Reach/Synchronous Transfer Mode (LR/STM)64 LH 1550.

●

One AIC-I.

●

According to normal consumption from Table 1, this configuration has this power consumption: (2
x 26.00W) + (2 x 78.60W) + (10 x 65.00W) + (2 x 72.20W) + 8.00W = 1011.60W + 95W (FTA3) =
1106.60W.

Given that input power eventually ends up as heat, use this formula to determine the maximum
thermal load of the ONS 15454 shelf:

Watts = BTUs/hr x 0.2930711

The thermal load on a fully loaded shelf is dependent on the cards in the shelf and their power
requirements.

According to the above specifications, a single ONS 15454 NEBS3 chassis can require up to
