Chapter 1      Connecting the Cisco MDS 9148S Switch
    Connecting to a Fibre Channel Port
Note Use only Cisco SFP transceivers on the Cisco MDS 9148S switch. Each Cisco SFP transceiver is 
encoded with model information that enables the switch to verify that the SFP transceiver meets the 
requirements for the switch.
The Cisco MDS 9148S switch supports SFP transceivers with the following two types of latching 
devices:
• Mylar tab latch (Figure 1-2)
• Bale-clasp latch (Figure 1-3)

Installing an SFP Transceiver
To install an SFP transceiver, follow these steps:
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Caution If the transceiver does not install easily, ensure it is correctly oriented and the tab or clasp are 
in the correct position before continuing.
Step 2 Remove the dust cover from the port cage.
Step 3 Remove the dust cover from the port end of the transceiver. 
Step 4 Insert the transceiver into the port:
• If the transceiver has a mylar tab latch, orient the transceiver with the tab on the bottom, and then 
gently insert the transceiver into the port until it clicks into place.
• If the transceiver has a bale-clasp latch, orient the transceiver with the bale clasp on the bottom, 
close the bale clasp by pushing it up and over the transceiver, and then gently insert the transceiver 
into the port until it clicks into place.
