About Your System 23CMC Daisy Chaining (Enclosure Stacking)CMC daisy chaining can be utilized to minimize the number of networkconnections required for chassis (enclosure) management, such that only oneor two network connections (depending on whether or not redundant CMCsare installed) are needed for up to four M1000e enclosures.Cabling GuidelinesFollow these guidelines to daisy chain CMC modules from enclosure toenclosure:• CMC Ethernet port GB1 is the Uplink port. It uplinks to either themanagement network, or to receive a cable from the CMC Ethernet portlabeled STK in the adjacent enclosure.The CMC Ethernet port labeled STK is the daisy-chain port. It connectsonly to CMC port GB1 on the adjacent enclosure. Do not connect thiscable directly to the management network.• Up to four enclosures can be daisy chained.• Enclosures can be daisy chained in both redundant and non-redundantdeployments:– In a redundant CMC deployment, cable all CMC modules in theCMC primary slots together. Cable all CMC modules in the CMCsecondary slots together.NOTE: Do not connect the primary daisy chain with the secondary daisychain (do not cross cable the two sets of CMCs).– In a non-redundant CMC, cable all CMC modules in the CMCprimary slots together.Figure 1-15 shows four enclosures with redundant CMC modules installed.Primary CMC port GB1 in the first enclosure connects to the managementnetwork. Primary CMC port GB1 in the adjacent enclosure is uplinked intothe port labeled STK on the primary CMC in the enclosure above it. No cableis required in port STK on the fourth enclosure in line. The same cablingscheme is valid for the daisy chain of CMC modules in the secondary slot ofthe enclosures.
