安裝指南
為此開關選擇了站點。如果指導方針是：未遵循，網絡性能不令人滿意這可能是結果。
? 確保適當的通風和防止過熱，留出最小間隙左、右和后部5.1厘米（2.0英寸）轉換不要將開關連接到交流電源電源，直到在安裝過程。
? 每個空氣入口的環境溫度開關必須保持在0°C和50°C之間（32°至122°F）。溫度變化必須保持在每小時10°C（18°F）以內。上行鏈路/交換機接口表3列出了24端口銅交換機和可以添加到交換機的上行鏈路接口。

INSTALLATION GUIDELINES
The following guidelines must be observed when a
site is selected for this switch. If the guidelines are
not followed, unsatisfactory network performance
may result.
? To ensure proper ventilation and prevent
overheating, leave a minimum clearance space of
5.1 cm (2.0 in) at the left, right, and rear of the
switch. Do not connect the switch to the ac
power source until instructed to do so later in the
installation process.
? Ambient temperature at the air inlet for each
switch must be maintained between 0° and 50°C
(32° to 122°F). Temperature changes must be
maintained within 10°C (18°F) per hour.
UPLINK/SWITCH INTERFACES
Table 3 lists the 24-Port Copper switch and the
uplink interfaces that can be added to the switch.
The uplink connectors are added to specific uplink
interfaces.(a) Kit P0973JD is comprised of two Mini-GBICs (P0973JB and P0973JC). P0973JC transmits “downstream” (from the core of the
network to the edge) uses the 1490 nm wavelength, and the “edge” P0973JB transmits “upstream” uses the 1310 nm wavelength.
(b) Kit P0973KP (40 km (25 mi)) is comprised of two Mini-GBICs (P0973KM and P0973KN). P0973KN transmits “downstream” (from the
core of the network to the edge) uses the 1490 nm wavelength, and the “edge” P0973KM transmits “upstream” uses the 1310 nm
wavelength over Simplex Single Mode Fiber (S-SMF).
(c) Kit P0973KS (120Km) is comprised of two Mini-GBICs (P0973KQ and P0973KR). P0973KR transmits “downstream” (from the core
of the network to the edge) uses the 1590 nm wavelength, and the “edge” P0973KQ transmits “upstream” uses the 1490 nm
wavelength over Simplex Single Mode Fiber (S-SMF) at a minimum distance of 30 km (19 mi).OVERVIEW
The 24-Port Fiber managed switch (P0973JN)
provides twenty-four 100Base-FX ports with MT-RJ
connectors, two fixed 10/100/1000 stacking / uplink
(ISL) ports and two 1000Base-X uplink (ISL) Gigabit
(SFP) ports.
The two 1000Base-X uplink (ISL) Gigabit (SFP) ports
can be populated with Mini-GBIC uplink (ISL)
connector modules listed in Table 4.
The switch allows high-performance, full-featured
layer-2 Ethernet switching in small to medium-sized
network applications, as well as high-performance
direct end-station connectivity.
FEATURES
The 24-Port Fiber managed switch features:
? 24-ports of 100Base-FX
? Two fixed RJ-45 10/100/1000 ports, configurable
for uplink
? Two 1000Base-X uplink Gigabit (SFP) ports
? MT-RJ connectors on switch ports
? Full duplex operation
? Supports VLAN configurations
? Monitoring and configuration tasks via local
console port, or any SNMP/RMON based
management application.
