What is the temperature of the S7700&S9700 in different situations

12

The temperature range of the S7700&S9700 is as follows:
Operating temperature: 0°C to 45°C
Storage temperature: -40°C to +70°C
You can run the display temperature command to view the temperature of the S7700&S9700 card.
If no alarm is generated, the device is working normally and the temperature is within the allowed range.

NOTE:
The set transceiver temperature threshold command sets the temperature threshold for adjusting the fan speed. When the temperature of an optical module exceeds the upper threshold, the fan speed is increased. When the temperature of an optical module falls below the lower threshold, the fan speed is reduced. The display transceiver temperature threshold command displays the upper and lower temperature thresholds for adjusting the fan speed.

How is the S7700&S9700 grounded
The chassis of an S7712 or S7706 has a ground screw on the lower right part of the front, and the chassis of an S7703 has a ground screw on the lower left part of the rear. The chassis of an S9712, S9706, or S9703 has a ground screw on the lower left part of the rear. Ensure correct grounding to guarantee the normal operation of the S7700&S9700.

What are the functions of the CF card of the S7700&S9700
The S7700&S9700 series switches support standard CF cards. The default capacity of a CF card is 512 MB, expandable to 1 GB or 2 GB. The CF card is used to store system files, configuration files, paf, License, and log files. The S7700&S9700 series switches can start by using the startup file in the CF card. In this case, the system software package is stored on the CF card. It is required to specify the system software package on the CF card as the boot file. On the S7700&S9700 series switches, logs can be stored on the CF cards. Do not use the uncertified CF cards to prevent unpredictable problems.

What are the types of the main control boards of the S7700&S9700

The details are as follows: -The ES0D00MCUA00 is installed on the S7703. -The ES0D00SRUA00, ES0D00SRUB00 and ES1D2SRUH000 are installed on the S7706 and S7712. The main control boards of the S9700 include EH1D2MCUAC00, EH1D2SRUDC00, EH1D2SRUDC01, and EH1D2SRUC000. The details are as follows: -The EH1D2MCUAC00 is installed on the S9703. -The EH1D2SRUDC00, EH1D2SRUDC01 and EH1D2SRUC000 are installed on the S9706 and S9712.

What are the differences between the E series, F series, and S series LPUs of the S7700&S9700
S7700&S9700 LPUs are classified into three series: E series, F series, and S series. The E series is the enhanced series, which supports Multiprotocol Label Switching (MPLS) and extension of routing, ACL, as well as MAC address entries. The E series consists of the EA, EC, ED, and EE LPUs. The F series is the ordinary series, and supports MPLS but not extension of MAC address entries. The F series consists of the FA and FC LPUs. The S series is the standard series and does not support extension of MAC address entries. The S series consists of the SA and SC LPUs. The SA LPUs do not support MPLS, whereas the SC LPUs support MPLS. NOTE: A, C, and D in the LPU names indicate the number of MAC address entries supported by the LPUs: A: 32K MAC addresses C: 128K MAC addresses D: 512K MAC addresses
