安装指南
为此开关选择了站点。如果指导方针是：未遵循，网络性能不令人满意这可能是结果。
确保适当的通风和防止过热，留出最小间隙左、右和后部5.1厘米（2.0英寸）转换不要将开关连接到交流电源电源，直到在安装过程。
每个空气入口的环境温度开关必须保持在0°C和50°C之间（32°至122°F）。温度变化必须保持在每小时10°C（18°F）以内。上行链路/交换机接口表3列出了24端口铜交换机和可以添加到交换机的上行链路接口。
上行链路连接器添加到特定上行链路接口。（a） 套件P0973JD由两个微型GBIC（P0973JB和P0973JC）组成。P0973JC传输“下游”（来自网络到边缘）使用1490nm波长，“边缘”P0973JB传输“上游”使用1310nm波长。（b） 套件P0973KP（40公里（25英里））由两个微型GBIC（P0973KM和P0973KN）组成。P0973KN传输“下游”（从网络核心到边缘）使用1490 nm波长，“边缘”P0973KM传输“上游”使用1310 nm波长
单工单模光纤（S-SMF）上的波长
（c） 套件P0973KS（120Km）由两个微型GBIC（P0973KQ和P0973K）组成。P0973KR传输“下游”（来自核心网络到边缘）使用1590 nm波长，“边缘”P0973KQ传输“上游”使用1490 nm波长单工单模光纤（S-SMF）上最小距离为30 km（19 mi）的波长。概述24端口光纤管理交换机（P0973JN）
提供24个带MT-RJ的100Base FX端口连接器，两个固定10/100/1000堆叠/上行链路

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.

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.
