• When you connect LAN cables to network interface connector 1, 2,
and extension network interface connectors of an optional LAN
mezzanine (CN7M0T-Y/CN7M0T-R/CN7M1T-Y/CN7M1T-R), follow
the following instructions. If you fail to do so, network interface
connectors can be damaged and LAN cables can be damaged or
disconnected.
Use LAN cables with connectors in compliance with
–
RJ45/ISO8877 standard.
Install the LAN cables in such a way that too much stress is not
–
placed on the network interface connectors.
When you disconnect a LAN cable, keep pressing the tab on the
–
cable connector and pull out the connector while keeping the
connector evenly aligned with the connector on the system unit.
When you connect LAN cables to extension network interface
•
connectors of an optional LAN mezzanine (CN7M1T-Y/CN7M1T-R),
follow the following instructions.
– Do not enabling the spanning tree setting of the port connected
the LAN cable to the switching HUB. Disable the spanning tree
setting.
– Do not setting the network port to 100 Mbps full-duplex mode or
half-duplex mode. May cause the operation to become unstable.
When you connect LAN cables to extension network interface
•
connectors of an optional LAN mezzanine (CN7M1S-Y/CN7M1S-R),
follow the following instructions. If you fail to do so, network
interface connectors can be damaged and LAN cables can be
damaged or disconnected.
Install LAN cables so that too much pressure is not placed on the
–
SFP+ module of the network interface connectors.
When you disconnect a LAN cable, pull down the lever on the
–
SFP+ module and pull out the connector while keeping the
connector evenly aligned with the connector on the SFP+
module.
Do not connect a LAN cable between the LAN mezzanine
–
(CN7M1S-Y/CN7M1S-R) and a Fiber type LAN network adapter
directly. Use a switching hub. Otherwise, a network may not link
up.
Connect LAN cables to network interface connectors (include
•
optional LAN mezzanine and LAN card) through a switching HUB. If
you connect LAN cables to network interface connectors directly, a
network may not link up.
