Connecting a Signal Cables for a C72 Node

Connecting a Signal Cables for a C72 Node

The section describes ports used by a C72 node If OceanStor 9000 uses the front-end GE service network and back-end 10GE storage network. C72 nodes connect to 10GE switches through signal cables. This section describes how to connect a CE6810-48S4Q-EI switch. You can use the same method to connect a CE6810-24S2Q-LI switch.

Prerequisites

  • Information about the current network and associated ports has been obtained.
  • Required components have been installed in the cabinet.
  • PGND cables and power cables have been connected to the components in the cabinet.
  • All required tools have been prepared, containing cable ties, diagonal pliers, and electrostatic discharge (ESD) gloves or an ESD wrist strap.

Storage Node Port Planning

If OceanStor 9000 uses the front-end GE service network and back-end 10GE storage network, ports on a C72 node are shown in Figure 10-21 and their usage is described in Table 10-10.

GE electrical port

Front-end service network

Connects to a GE switch on the customer's service network.

NIC0

GE electrical port

Management network

Each C72 node has two interface boards and each board has one NIC0 port, that is, each C72 node provides two NIC0 ports.

Switch Port Planning

Ports on a CE6810 10GE switch in a basic cabinet are shown in Figure 10-22, and their usage is described in Table 10-11.

10GE SFP+ Ethernet optical port

Back-end network

Each CE6810 switch connects to nodes through 40 ports in sequence.

  • Switch CE6810-1 connects to ports P0 on two interface boards of the C72 node.
  • Switch CE6810-2 connects to ports P1 on two interface boards of the C72 node.

Stack ports are used in the sequence from 1 to 4. The usage of stack ports is as follows:

  • When the number of nodes is not larger than 8, use at least two ports for stacking switches.
  • When the number of nodes is larger than 8 but not larger than 12, use at least three ports for stacking switches.
  • When the number of nodes is larger than 12 but not larger than 20, use at least four ports for stacking switches.

Connect to the S5752/S5352 GE switch.

In the basic cabinet, the S5752/S5352 GE switch ports for connecting to the management and maintenance network are shown in Figure 10-23, and the port usage is described in Table 10-12.

Procedure

  1. Wear an ESD wrist strap or ESD gloves.
  2. Determine port numbers of the storage node and signal cable connection modes.
  3. Obtain the required types of cables and label them.
  4. Optional: 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 10-24.

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

      Figure 10-24  Installing an optical module

  5. Connect cables according to the attached label.

    • To connect a copper cable, hold a copper cable connector in a correct direction when inserting it into a port. When you hear a click, the copper cable is securely connected to the port.
    • To remove a copper cable, gently push the cable connector and then pull the handle of the connector. Do not directly pull the cable connector with force, as shown in Figure 10-25.
      Figure 10-25   Removing a copper cable

    • After connecting cables to the devices, reserve adequate cable slack for ease of operation on other FRUs.

  6. Route and bind the cables on the cable manager.
    1. Bind all the signal cables on the right (including SFP+ high-speed cables and network cables). Positions 1 in Figure 10-26 are where the cables are bound to enter the cable manager.
    2. Bind all the signal cables on the right with the power cables to the handle of the fan module. Positions 2 in Figure 10-26 are where the cables are bound to enter the cable manager.
    3. Bind all the cables on the right (including signal cables, power cables, and ground cables) to the front end of the cable manager. Positions 3 in Figure 10-26 are where the cables are bound to enter the cable manager.
    4. Route and bind cables along the trough of the cable manager. Positions 4 in Figure 10-26 are where the cables are bound to enter the cable manager.
    5. Route and bind cables along the trough of the cable manager. Positions 5 in Figure 10-26 are where the cables are bound to get out of the cable manager.

    Repeat the previous steps to route and bind cables onto the left cable manager.

    NOTE:

    Evenly divide the cables connected to the storage device into two parts. Place the left part of cables into the troughs of the left cable manager, and the right part in the troughs of the right cable manager.

  7. Lay out the cables along the mounting bars neatly, use cable ties to bind them, and trim off the excess of cable ties using diagonal pliers.

Example

In the following example, there are two C72 nodes deployed and the front-end service network uses the GE network and the back-end storage network uses the 10GE network.
