HP HSR6602 Router Series FAQ
6
Q.
Why do CRC errors occur on the ports of the router?
A. If port autosensing is successful and the duplex modes on the two ends are the same, the link might fail. For
example, twisted pairs, fibers, intermediate devices, and fiber-to-copper converters might fail.
Q.
Can I connect a 1000 Mbps transceiver to a 100 Mbps transceiver?
A. You cannot directly connect a 1000 Mbps transceiver to a 100 Mbps transceiver. To do so, set the
100/1000 Mbps transceiver to operate in 100 Mbps mode.
Q.
Do I need to configure the full duplex and port speed when I connect a copper port and a fiber port?
A. If port autosensing fails, you must configure both the full duplex mode and the port speed on both ports.
Q.
Will fibers be affected if they are deployed with 10 kW high-voltage cables?
A. No. Optical signals are not affected by high-voltage signals.
Q.
Does the router provide built-in CF cards or support external CF cards?
A. The router has a built-in 512 MB Nand Flash. You can install a 256 MB, 512 MB, or 1 GB CF card in the
router.
Q.
Is the CF card on the router hot swappable?
A. Yes. To avoid damage to the file system, execute the umount command to unmount the CF card before you
unplug a CF card.
Q.
Does the router support CF cards provided by a third party?
A. No. The router is compatible with CF cards provided only by HP.
Q.
Does access to a damaged CF card cause disconnection from the VTY?
A. No. The VTY stops accessing the CF card after multiple access failures.
Q.
What are the types of USB ports on MPUs of the router?
A. The router provides USB2.0 A-type USB ports. The USB ports enable connection to external storage devices,
such as a USB flash disk, for storage and transfer of files and logs.
Q.
What types of USB disks does the router support?
A. The router is compatible with USB disks provided only by HP.
