• 7008XT-MDA — provides 8 10GBASE-T ports
Note:
Half duplex is not supported on 10GBASE-T ports.
The 7008XT-MDA 10GBASE-T ports comply to IEEE 802.3an specification, supporting
10Gbps connections over unshielded or shielded twisted pair cables, over distances up to 100
metres (330 ft).
Important:
Category 6A or better balanced twisted pair cables are required to carry 10Gbps up to 100
m. Category 6 cables can carry 10Gbps up to 55 m.
MDA warm swap
Media Dependent Adapter (MDA) warm swap is supported. You can warm insert, warm
remove, or hot remove an MDA.
You can perform a warm insert by enabling the MDA once it is inserted in a unit. You must
enable an MDA for the MDA ports to function. An MDA insertion event does not interrupt traffic
within the switch or stack.
You can perform a warm removal by disabling the MDA before removal. A warm removal
ensures MDA egress traffic routes to an operating switch port. Hot removal is also supported,
however a hot removal can cause packet loss. Once an MDA is hot removed, packets
scheduled to egress the MDA ports are discarded, and an unsafe MDA removal log message
is generated.
When the MDA is disabled, you cannot modify the MDA port settings. The MDA settings for
auto-negotiation, auto-negotiation advertisements, speed, duplex, flow control, rate-limiting,
and admin status default when the MDA becomes active. All other applications with per-port
configurations, such as MLT, VLAN, etc, do not default when the MDA operational status
changes. For more information about MDA configuration, see
