10/100/1000 Ethernet cabling

The 10/100/1000 Ethernet switch provides an optional 10/100/1000 network for
communications between cluster nodes and storage nodes.
Each intercabinet cables have labels at both ends of each cable. You can use the
information on the label to create a site map to document all cable routing.

Fibre Channel cabling

Fibre Channel is used to connect storage nodes to storage servers and to connect
storage servers to storage expansion units.
Each intercabinet cable has labels at both ends. You can use the information on the
label to create a site map to document all cable routing.

KVM cabling

The KVM switch allows a maximum of eight connections. Use the following
guidelines for cabling the KVM switch:
v Use the information on each end of each cable to create a site map.
v When routing a KVM cable from a cabinet containing cluster nodes to another
v Multiple KVM switches can be connected in series. Cluster nodes (xSeries 335
v When using two KVM switches, connect Port A (the console port) of switch 2 to

Remote Console Manager cabling

The Remote Console Manager (RCM) switch has 16 ACT connections (KVM over
RJ-45/Cat 5) and one KVM connection for the console. Use the following guidelines
for cabling the RCM switch:
v Use the information on each end of each cable to create a site map.
v When routing a Cat 5 KVM cable from a cabinet containing cluster nodes to the
v Multiple KVM switches can be connected in series.
v Up to 40 cluster nodes (xSeries 335 server) can be connected in series to each
cabinet containing the KVM switch, connect a C2T-to-KVM cable to the cluster
nodes and use a KVM extension cable to add sufficient length to reach the KVM
switch.
server) can be connected in series to a single KVM switch port (up to 40 cluster
nodes), but the management node and all the storage nodes each require a
separate KVM switch port. Certain systems might require a second KVM switch.
Install the second switch in the expansion cabinet that contains the additional
storage nodes.
port 8 of switch 1. Use a KVM extension cable to make the connection between
the two cabinets. If more length is needed, use two KVM extension cables linked
together.
cabinet containing the RCM, use a CCO cable and a Cat 5 cable sufficiently long
enough to reach the RCM switch.
ACT port on the RCM. The management node and all the storage nodes can
also be daisy-chained, with up to 16 per ACT port. Multiple RCMs can not be
daisy-chained together. The RCM can be connected to an Ethernet network to
allow for remote access to the consoles of the servers over the network.
