One high-density expansion enclosure, seven standard-density expansion enclosures
or
Eight standard-density expansion enclosures
7
Two high-density expansion enclosures, five standard-density expansion enclosures
or
Seven standard-density expansion enclosures
5
Three high-density expansion enclosures, two standard-density expansion enclosures
or
Five standard-density expansion enclosures
4

• Expansion enclosure only
Each 2U enclosure requires two standard rack units of space in a rack. Identify the appropriate location
for each enclosure by using the numbers on the front of the rack. When you add a single expansion
enclosure to an existing network, it is preferable to add the enclosure directly below the control
enclosure. When you add a second expansion enclosure, it is preferable to add the enclosure directly
above the control enclosure. As more expansion enclosures are added, alternate adding them above
and below the control enclosure.
Network cable connections worksheet
During the planning process, complete the cable-connection tables with the locations of the cable
connections for each control enclosure in the system.
Ethernet connections
Each node canister in the control enclosure connects over an Ethernet cable from Ethernet port 1 of the
canister to an enabled port on your Ethernet switch or router. Ethernet port 1 is for accessing the
management GUI, for accessing the service assistant GUI for the node canister, and for iSCSI host
attachment. You can attach an Ethernet cable from Ethernet port 2 on the canister to your Ethernet
network. Port 2 can be used for the management GUI and for iSCSI host attachment. Ports 3 and 4 are for
iSCSI attachment only.
Note: The ports on the upper node canister (canister 1) are numbered from right to left. However, the
ports on the lower node canister (canister 2) are numbered from left to right.
Ethernet cable standards
The following table provides a list of Ethernet cable standards.
