[. . . ] Holding the module level, guide it into the carrier rails on each side and gently push it all the way into the slot, ensuring that it firmly engages with the connector. 3-7 INSTALLING THE SWITCH 5. If you are sure the module is properly mated with the connector, tighten the retainer screws to secure the module in the slot. To confirm that the module is correctly installed and ready to use, connect an active device to the module, and verify that the corresponding port indicator on the switch's front panel turns green to show that there is a valid link. Installing an Optional SFP Transceiver Mgmt Figure 3-6 Inserting an SFP Transceiver into a Slot This switch supports 1000BASE-SX/LX/ZX SFP-compatible transceivers. To install an SFP transceiver, do the following: 1. Consider network and cabling requirements to select an appropriate SFP transceiver type. Insert the transceiver with the optical connector facing outward and the slot connector facing down. Note that SFP transceivers are keyed so they can only be installed in one orientation. Slide the SFP transceiver into the slot until it clicks into place. 3-8 GROUNDING THE CHASSIS Notes: 1. The switch does not need to be powered off before installing or removing a transceiver. However, always first disconnect the network cable before removing a transceiver. SFP transceivers are not provided in the switch package. Grounding the Chassis Before powering on the switch, ground the switch to earth as described below. Ensure that the rack on which the switch is to be mounted is properly grounded and in compliance with ETSI ETS 300 253. Ensure that there is a good electrical connection to the grounding point on the rack (no paint or isolating surface treatment). Disconnect all power cables to the switch. The switch chassis is connected internaly to 0 V. This circuit is connected to the single-hole grounding terminal on the back of the switch. The surface area around this terminal is not painted in order to provide for a good connection. Attach a 6 AWG stranded copper wire to the grounding terminal on the switch. Then attach the grounding wire to the ground point on the rack. Caution: The earth connection must not be removed unless all supply connections have been disconnected. 3-9 INSTALLING THE SWITCH Connecting to a Power Source This switch supports both AC and DC power conversion modules. Connecting DC Power When a -48 VDC power conversion module is installed in the switch, an external DC power supply must be connected to the DC power connection on the left side of the front panel. Warning: Before wiring the DC plug or connecting power to the switch, ensure that power to the feed lines is turned off at the supply circuit breaker or disconnected from the power bus. To provide adequate circuit protection between the DC power supply and the switch, all intermediate wiring and circuitry should be rated to carry a load at least two times the maximum rating for this switch (see "Power Supply" on page C-2). [. . . ] The successor IEEE 802. 3 standard provides for integration into the OSI model and extends the physical layer and media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable.
