Configuring the Switch

IP Address  Address of the VLAN interface that is allowed management access.. Valid IP addresses consist of four numbers, 0 to 255, separated by periods.. (Default: 192.168.1.254)

Subnet Mask  This mask identifies the host address bits used for routing to specific subnets.. (Default: 255.255.255.0)

Default Gateway  IP address of the gateway router between this device and management stations that exist on other network segments.. (Default: 0.0.0.0)

DNS Server  Enter the IP address of the DNS server into the text field.. A second DNS address can be specified in the additional text field provided..

Click Save Settings to save the changes..

Click Restart DHCP to assign a new IP address using DHCP..

Setup > Time

Simple Network Time Protocol (SNTP) allows the Switch to set its internal clock based on periodic updates from a time server (SNTP or NTP).. Maintaining accurate time on the Switch enables the system log to record meaningful dates and times for event entries.. If the clock is not set, the Switch will only record the time from the factory default set at the last bootup.. When the SNTP client is enabled, the Switch periodically sends a request for a time update to a configured time server.. You can configure up to two time server IP addresses.. The Switch will attempt to poll each server in the sequence..

Set Time

Set the system time manually  This option allows you to set the time and date manually for the Switch..

Set the system time using Simple Network Time Protocol (SNTP) automatically  Sets the system clock automatically using SNTP..

Manual

Hours  The hour is entered here..

Minutes  The minutes is entered here..

Seconds  The seconds is entered here..

Month  The month is entered here..

Day  The day is entered here..

Year  The year is entered here..

Automatic

Sets the system clock automatically using SNTP..

Time Zone  Set the time zone by selecting it from the drop-down menu..

Daylight Savings  Enable daylight saving time by checking the checkbox.. Then set USA, Europe, or custom daylight saving time by clicking the appropriate option..

Time Set Offset  Custom daylight saving time is set by entering the time difference in minutes into the Time Set Offset field.. Set the date for this offset by entering the day and month (DD/MM) in the From and To fields..

Recurring  To enable a recurring custom daylight savings time, check the Recurring checkbox.. Set the day, week, and month the time difference will be recurring (From and To) by using the drop-down menus.. Set the time (From and To) of the recurrence using the field provided (HH:MM)..

SNTP Servers 

Sets the IP address of up to two SNTP servers.. Server 1  Set the IP address of the SNTP server..

Server 2  Set the IP address of an additional SNTP server..

Polling Internal (16-16384 sec)  The value entered here determines the number of seconds between each time the Switch contacts the SNTP server for an update..

SRW248G4P specifications

Cisco Systems SRW248G4P is a high-performance Layer 2 switch designed specifically for small to medium-sized businesses that require robust networking solutions. This switch supports Power over Ethernet (PoE), providing a highly flexible option for powering devices such as IP phones, wireless access points, and surveillance cameras.

One of the standout features of the SRW248G4P is its 48 10/100 Ethernet ports, which ensure ample connectivity for various networked devices. Additionally, it offers four Gigabit Ethernet uplink ports, allowing for seamless integration with existing network infrastructure and facilitating high-speed data transfer. The combination of these ports enables businesses to expand their network capabilities as needed without the immediate requirement for added devices.

The SRW248G4P comes equipped with advanced Layer 2 switching capabilities, including VLAN support, which enables the segmentation of network traffic for improved performance and security. It also supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), which help prevent network loops and ensure redundancy. With features like Link Aggregation Control Protocol (LACP), multiple physical connections can be combined into a single logical link, enhancing bandwidth and providing failover capabilities.

Another critical attribute of the Cisco SRW248G4P is its user-friendly management interface. The switch can be managed through a web-based interface, allowing IT administrators to configure settings, monitor performance, and troubleshoot issues with ease. Additionally, it supports SNMP (Simple Network Management Protocol) for integration with network management systems, further simplifying monitoring tasks.

Power over Ethernet functionality is a significant advantage of the SRW248G4P, providing up to 15.4 watts per port. This capability simplifies installation and reduces the clutter of power cords and outlets. Organizations can deploy PoE-enabled devices in locations that lack power sources, thus enhancing overall flexibility in network design.

In summary, the Cisco Systems SRW248G4P is a feature-rich switch tailored for small to medium-sized enterprises. Its blend of performance, management capabilities, and advanced features like PoE makes it a valuable asset in any organization's networking setup. By ensuring reliable connectivity and ease of management, businesses can focus more on growth and their core objectives rather than worrying about network complexities.
