The DDR of the CE6870-48T6CQ-EI has been optimized and upgraded since March 1, 2020. The switches that are manufactured on and after March 1, 2020 can only run V200R019C10SPC800 after the corresponding patch is load, as well as running V200R020C10 or later versions. (The year and month when the switches are manufactured can be determined based on the SN.)

The product SN consists of 20 characters.

The thirteenth character indicates the year of production. A indicates 2010, B indicates 2011, C indicates 2012, D indicates 2013, E indicates 2014, F indicates 2015, G indicates 2016, H indicates 2017, J indicates 2018, K indicates 2019, and L indicates 2020. The letter I is not used. The letters increase with the year.
The fourteenth character indicates the month of production. 1 indicates January, 2 indicates February, …, 9 indicates September, A indicates October, B indicates November, and C indicates December.

For example, if the SN of a switch is 2102XXXXXX10L3000XXX, the switch is manufactured in March 2020.

Slot

Power supply slot

The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI) have two power supply slots, in which power modules can be installed to provide power to the chassis. A chassis can have one or two power modules. Double power modules can provide higher reliability.
The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI) support double power modules (1+1 backup).
- When both power modules are working properly, they equally provide power for a chassis.
- When one power module fails, the other one provides all power required for a chassis.
All power modules are hot swappable.
Fan slot

The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI, CE6863-48S6CQ, CE6881-48S6CQ, CE6820-48S6CQ, CE6863-48S6CQ-K, CE6881-48S6CQ-K, CE6881E-48S6CQ and CE6857-48S6CQ-EI) have two fan slots, in which fan modules can be installed to cool the chassis, ensuring efficient heat dissipation and system stability. A chassis must have two working fan modules to ensure normal operating.

All fan modules are hot swappable.

Airflow

The cooling systems of the CloudEngine 8800, 7800, 6800, and 5800 series switches have front-to-back or back-to-front airflow depending on the airflow direction of the power modules and fan modules used. The airflow direction of the power modules and fan modules required on the CloudEngine 8800, 7800, 6800, and 5800 series switches depends on how the switches are installed in cabinets. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If CloudEngine 8800, 7800, 6800, and 5800 series switches are installed with the power supply side facing the front, you are advised to use fan modules and power modules with front-to-back airflow in the switches.

Front-to-back airflow: The power modules and fan modules using front-to-back airflow are marked or . Air flows into the chassis from the power supply side and flows out from the port side, as shown in Figure 2-122 (CE5800 as an example).
Back-to-front airflow: The power modules and fan modules using back-to-front airflow are marked or . Air flows into the chassis from the port side and flows out from the power supply side, as shown in Figure 2-110 (CE5800 as an example).
When the power module and fan module use forcible heat dissipation, they must use the same airflow method. For example, if the power module with back-to-front airflow is used, the fan module with back-to-front airflow must be used.

Indicators

The downlink service port indicators of the CE6870-48T6CQ-EI are 10GE electrical port indicators, and other indicators are the same as those on the CE6870-48S6CQ-EI. The CE6870-48S6CQ-EI is used as an example here to describe the indicators.
