Poe (Gs1100-10Hp); Sfp Slots (Gs1100-24 And Gs1100-10Hp) - ZyXEL Communications GS1100 Series User Manual

When auto-negotiation is turned on, an Ethernet port negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-
negotiation or turns off this feature, the Switch determines the connection speed by detecting the signal
on the cable. When the Switch's auto-negotiation is turned off, an Ethernet port uses the pre-configured
speed and duplex mode when making a connection, thus requiring you to make sure that the settings
of the peer Ethernet port are the same in order to connect.
All ports support auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so you
may use either a straight-through Ethernet cable or crossover Ethernet cable for all Gigabit port
connections. Auto-crossover ports automatically sense whether they need to function as crossover or
straight ports, so crossover cables can connect both computers and switches or hubs.

3.1.4 PoE (GS1100-10HP)

The Switch supports the IEEE 802.3af Power over Ethernet (PoE), IEEE 802.3at Power over Ethernet (PoE)
plus. The Switch is a Power Sourcing Equipment (PSE) because it provides a source of power via its
Ethernet ports. Each device that receives power through an Ethernet port is a Powered Device (PD).

3.1.5 SFP Slots (GS1100-24 and GS1100-10HP)

These are slots for SFP (Small Form-Factor Pluggable) transceivers. A transceiver is a single unit that
houses a transmitter and a receiver. The Switch does not come with transceivers. You must use
transceivers that comply with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement
(MSA). See the SFF committee's INF-8074i specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different transceivers to
connect to Ethernet switches with different types of fiber or even copper cable connectors.
• Type: SFP connection interface
• Connection speed: 100/1000 Mbps
WARNING! To avoid possible eye injury, do not look into an operating
fiber module's connectors.
HANDLING! All transceivers are static sensitive. To prevent damage from
electrostatic discharge (ESD), it is recommended you attach an ESD
preventive wrist strap to your wrist and to a bare metal surface when
you install or remove a transceiver.
STORAGE! All modules are dust sensitive. When not in use, always keep
the dust plug on. Avoid getting dust and other contaminant into the
optical bores, as the optics do not work correctly when obstructed with
dust.
3.1.5.1 Transceiver Installation
Use the following steps to install a transceiver.
Attach an ESD preventive wrist strap to your wrist and to a bare metal surface.
