3 Appendix B Removable components and compatibility matrixes

The S6520X-SI switches (except the S6520X-10XT-SI and S6520X-16XT-SI) use modular design and support removable components. Table3-1 and Table3-2 describe the removable components available for the switches and the compatibility between the removable components and the switches.

The S6520X-10XT-SI and S6520X-16XT-SI switches use one built-in power supply and two built-in fan trays and do not support removable components.

IMPORTANT:

· An S6520X-18C-SI switch must use PSR150-A1 or PSR150-D1 power supplies for power supply when it is installed with an LSPM6FWD or LSPM6FWD8 firewall module.

· An S6520X-26C-SI switch must use PSR150-A1 or PSR150-D1 power supplies for power supply when it is installed with an LSWM2SP8P, SWM4SP8PM, LSWM2XMGT8P, or LSWM2MGT8P interface card or an LSPM6FWD firewall module.

For an S6520X-16ST-SI, S6520X-24ST-SI, S6520X-18C-SI, S6520X-26C-SI, or S6520X-26MC-SI switch, you can install one power supply, or two power supplies for redundancy on the switch. AC and DC power supplies can be installed in the same chassis.

For an S6520X-26MC-UPWR-SI, S6520X-26XC-UPWR-SI, or S6520X-54XC-UPWR-SI switch, you can install one power supply, or two power supplies for redundancy on the switch. PoE capabilities vary by power supply configuration. When a power supply fails, PoE capabilities of the switch might decrease. For more information about PoE power, see Table1-4.

The S6520X-26XC-UPWR-SI and S6520X-54XC-UPWR-SI switches use removable fan trays. Before powering on the switch, make sure all fan tray slots have fan trays installed and the fan trays are the same model.

The removable components available for the switch are subject to change over time. For the most recent list of removable components available for the switch, see the release notes that come with the switch.

IMPORTANT:

The ports on the LSWM2SP2PM and LSWM2XGT2PM interface cards can operate only at 10 Gbps when the cards are installed on the switch.

NOTE:

An LSPM6FWD or LSPM6FWD8 firewall module (including its handle) adds 75 mm (2.95 in) to the chassis depth when installed on the switch.

Connecting cables to the copper ports on the interface cards

An LSWM2XGT2PM interface card provides copper ports. To connect cables to the copper ports on an LSWM2XGT2PM interface card, follow these guidelines:

· Use Category-6A or above cables and connectors. The max transmission distance varies by cable type:

¡ Category-6 UTP—55 m (180.45 ft).

¡ Category-6 STP—100 m (328.08 ft), no interference.

¡ Category-6 SFTP—100 m (328.08 ft).

¡ Category-6A or above twisted pair—100 m (328.08 ft).

· Do not bundle cables in their first 20 m (65.62 ft).

· Separate power cords and twisted pair cables at and around the distribution frame.

· For ports adjacent to one another on the device, the peer ports on the distribution frame is preferably not adjacent, for example:

¡ If the device connects to one distribution frame, connect port 1 on the device to port 1 on the distribution frame and port 2 on the device to port 3 on the distribution frame.

¡ If the device connects to two distribution frames, connect port 1 on the device to port 1 on distribution frame 1 and port 2 on the device to port 1 on distribution frame 2.

· Keep the device and twisted pair cables away from the interference source, such as a two-way radio and a high-power variable-frequency drive.

IMPORTANT:

The QSFP+ ports on an LSWM2QP2P interface card do not support the QSFP-40G-LR4-PSM1310 transceiver module.

You can use a QSFP-40G-SR4-MM850, QSFP-40G-CSR4-MM850, or QSFP-40G-LR4-PSM1310 transceiver module to connect a QSFP+ port to four SFP+ ports. The QSFP+ transceiver module and SFP+ transceiver modules to be connected must be the same in specifications, including central wavelength and fiber type.

NOTE:

· As a best practice, use H3C QSFP+ transceiver modules, QSFP+ cables, or QSFP+ to SFP+ cables for the QSFP+ ports on the switch. The H3C QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to SFP+ cables available for the QSFP+ ports are subject to change over time. For the most recent list of QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to SFP+ cables available for the QSFP+ ports, contact H3C Support or marketing staff.

· For more information about H3C QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to SFP+ cables, see H3C Transceiver Modules User Guide.
