Installing a 10GE/25GE Switch

Installing a 10GE/25GE Switch

Installing a 10GE/25GE switch to a cabinet is a process for installing mounting ears, connecting a PGND cable to the 10GE/25GE switch, sliding the 10GE switch into the cabinet, and installing a pluggable optical module.


  • The installation environment meets requirements.
  • Guide rails in the cabinet have been installed.
  • All required tools have been prepared, containing Phillips screwdrivers, M4 screws, M6 screws, and protective gloves.


  • CE6810-48S4Q-EI/CE6810-24S2Q-LI/CE6851-48S6Q-HI/CE6855-48S6Q-HI switch (CE6800 for short) is applicable to a 10GE rear-end network for node interconnection and communication.
  • The CE6810-48S4Q-EI/CE6851-48S6Q-HI/CE6855-48S6Q-HI switch provides 48 x 10GE SFP+ Ethernet optical ports, capable of connecting to 48 storage nodes. The CE6810-24S2Q-LI switch provides 24 x 10GE SFP+ Ethernet optical ports, capable of connecting to 24 storage nodes. At the initial deployment, if the number of nodes is not smaller than 32, CE12800 series switches are recommended for easy capacity expansion. For details on how to install the CE12800 series switches, refer to the accompanying documents.
  • When all storage nodes (P12E/P25E/P36E/C36E) are installed in one cabinet, the CE6810-48S4Q-EI/CE6810-24S2Q-LI/CE6851-48S6Q-HI/CE6855-48S6Q-HI switches also need to be installed in the cabinet.
  • When all storage nodes (P12E/P25E/P36E/C36E) are installed in two or more cabinets, each of the first two cabinets needs to be equipped with one CE6810-48S4Q-EI/CE6810-24S2Q-LI/CE6851-48S6Q-HI/CE6855-48S6Q-HI switch.


  1. Wear protective gloves.
  2. Install mounting ears on the enclosure.

    Use six M4 screws to secure the two mounting ears to both sides of the CE6800 switch, as shown in Figure 8-84.

  3. Install a PGND cable.

    After the CE6800 switch is installed into the cabinet, there is no adequate room left in the cabinet for installing the PGND cable since the ground screw of the CE6800 switch is on its side. Therefore, it is advisable to install the PGND cable before sliding the CE6800 switch into the cabinet.

    If the PGND cable is not preinstalled on the CE6800 switch, install it onsite.

    1. Take out an accompanying PGND cable.
    2. Use a Phillips screwdriver to unfasten the M4 screw in the ground terminal.
    3. Use the Phillips screwdriver to secure one end of the PGND cable to the ground terminal of the CE6800 switch, as shown in Figure 8-85.


      When securing the PGND cable to the ground terminal of the CE6800 switch, ensure that the PGND cable is secured in parallel with the cabinet to prevent the PGND cable from being obstructed.

  4. Slide the CE6800 switch to the cabinet until the mounting ears are pressed against the mounting bars of the cabinet. Use the Phillips screwdriver and four M6 screws to secure the CE6800 switch to the cabinet, as shown in Figure 8-86.

    • Secure the two screws in the upper and lower parts of a mounting ear if L-shaped guide rails are used.
    • Secure the screw in the upper part of a mounting ear if L-shaped adjustable guide rails are used.

    The following figure takes the L-shaped guide rails as an example.

  5. Install an optical module.

    • Wear an ESD wrist strap or gloves to prevent damaging ESD-sensitive optical modules.
    • Do not insert an optical module reversely. If an optical module cannot be completely inserted into an optical module slot, do not force it into the slot. Turn the optical module over and try again.
    • Do not remove dust-proof caps from optical connectors before connecting optical fibers to optical modules.
    • Optical modules and optical fibers support only multi-mode optical modules.

    1. Take out an optical module from an ESD bag and verify that the optical module is intact.
    2. Insert the optical module into an optical port on the subcard until it snaps into place and then raise the handle to lock it up, as shown in Figure 8-87.

      When the locking reed of the optical module makes a "click" sound, the optical module is installed correctly.
